PEEK-LCF Polyether ether ketone (abbreviated PEEK) not only has excellent mechanical, heat and chemical resistance properties, and low friction coefficient, good bearing meshing, is another kind of good self-lubricating material after polytetrafluoroethylene (PTFE), in the bearing capacity and wear resistance than PTFE performance is better, In no lubrication, low speed and high load, high temperature, humidity, pollution, corrosion and other harsh environment is especially suitable. On this basis, the addition of carbon fiber not only enhances its mechanical properties, its friction performance has important ‌ influence. At room temperature, the tensile strength of 30% carbon fiber reinforced PEEK composite doubled, and reached three times at 150℃. At the same time, the impact strength, bending strength and modulus of the reinforced composite were also greatly improved, the elongation was sharply reduced, and the thermal deformation temperature could exceed 300℃. The impact energy absorption rate of the composite directly affects the impact performance of the composite. The carbon fiber reinforced PEEK composite shows a specific energy absorption capacity of up to 180kJ/kg. The reinforced effect of carbon fiber can also resist the thermal softening of PEEK and form a transfer film with very high strength to a certain extent, which can effectively protect the contact area. Therefore, the friction coefficient and specific wear rate of carbon fiber reinforced PEEK composite are significantly lower than that of pure PEEK. Under the same experimental conditions, the friction and wear resistance of carbon fiber reinforced PEEK composites is obviously better than that of glass fiber PEEK composites, and the improvement effect of carbon fiber on the wear resistance of materials is more than 5 times that of glass fiber with the same dosage. Carbon fiber reinforced PEEK composite material is used in parts manufacturing, which can effectively avoid the surface cracks of metal or ceramic materials, and its excellent tribological properties even exceed that of ultra-high molar mass polyethylene. TDS Application Long carbon fiber reinforced PEEK is mainly applied in the following four areas: 1. Electronic and electrical appliances PEEK can maintain good electrical insulation in the harsh environment such as high temperature, high pressure and high humidity, and has the characteristics of non-deformation in a wide temperature range, so it is used as an ideal electrical insulation material in the field of electronic and electrical appliances. The mechanical properties, chemical corrosion resistance, radiation resistance and high temperature resistance of polyether ether ketone reinforced by carbon fiber have been further improved, and its application fields have been further expanded. 2. Aerospace Polyether ether ketone PEEK has the advantages of low density and good workability, so it is easy to be directly processed into high-demand parts, and carbon fiber reinforced polyether ether ketone composite material further enhances the overall performance of polyether ether ketone, so it is increasingly used in aircraft manufacturing. The fairing on Boeing's 757-200 series aircraft, for example, is made from carbon-fiber reinforced PEEK. In addition, Gereedschappen Fabrick of Amsterdam, the Netherlands, used a 30% carbon fiber reinforced PEEK composite to build a larger component and demonstrated that its mechanical properties could be used in aircraft balancing devices. 3. Automotive Automobile energy consumption is closely related to vehicle weight. Automobile lightweight can not only reduce fuel consumption and exhaust emissions, but also improve power performance and safety, which is an effective way to save energy. In addition to the lightweight design of the structure, the use of lightweight materials is a more direct method. With its advantages of low density, good performance and convenient technology, carbon fiber reinforced polyether ether ketone composites are more and more frequently used in the automobile industry, and show great potential of replacing steel with plastic. For example, Robert Bosch GmbH uses carbon fiber reinforced PEEK instead of metal as a feature of ABS. The lighter composite part reduces moment of inertia, which minimizes reaction times, greatly enhances the overall system's reactivity, and reduces costs compared to previously used metal parts. 4. Healthcare Currently available medical polymer materials are polytetrafluoroethylene, polylactic acid, silicone rubber and dozens of kinds, but from the point of view of biomedicine, these materials are not ideal, in the use of some side effects, and PEEK resin because of its non-toxic, light weight, abrasion resistance and other advantages, is the material closest to the human skeleton, can be organically combined with the body, Therefore, polyether ether ketone resin and its composite materials have been deeply studied and applied in spine and joint...

What is PEEK? Polyether ether ketone (PEEK) is a semi-crystalline thermoplastic polymer material with rigid benzene ring, compliant ether bond and carbonyl group which can promote the intermolecular force in its molecular chain. PEEK has excellent wear resistance, electrical insulation, anti-radioactivity, chemical stability, biocompatibility and thermal stability. In addition, PEEK is reusable and has a high recovery rate. PEEK is widely used in aerospace, electronic and electrical appliances, biomedicine, Marine protection, automobile industry and other fields. PEEK material is an inert material with low surface free energy, and its mechanical properties and frictional properties cannot meet the needs of some special fields. Therefore, it is necessary to modify PEEK composite material to improve its comprehensive properties. At present, filling modification and blending modification are the main methods for preparing PEEK composite materials. Filler modified reinforcement materials mainly include fiber, inorganic particles and whisker; The polymer used for blending modification should have similar polarity and solubility to PEEK. The interface modification method can improve the interface adhesion and enhance the comprehensive properties of PEEK composites. What is PEEK filling Long Carbon Fiber? As a filling system, fiber can effectively carry part of the load, and the synergistic action between fiber and PEEK can improve the comprehensive performance of composite materials. Carbon fiber and glass fiber are widely used as filler modified composites because of their high strength, high modulus and high durability. Long carbon fiber (LCF) can be used as heterogeneous nucleating agent to promote the crystallization of PEEK in composite materials, which can effectively improve the mechanical and tribological properties of composite materials. PEEK/CF composites of different lengths were prepared by injection molding, and their infiltrating and tribological properties were studied. The results show that the addition of CF increases the contact Angle and decreases the hydrophilicity of the composites. But the friction coefficient of composites is reduced and the friction resistance is improved. Long carbon fiber (LCF) has better effect on reducing friction coefficient than short carbon fiber (SCF). TDS of PEEK for reference Application of PEEK CF Q&A 1. What are the advantages of long carbon fiber materials? A: Thermoplastic LFT Long carbon fiber material has high rigidity, good impact strength, low warpage, low shrinkage, electrical conductivity and electrostatic propertiea, and its mechanical properties are better than glass fiber series.

Are there any special process requirements of long carbon fiber injection molding products? A: We must consider the requirements of long carbon fiber for the injection molding machine screw nozzle, mold structure and injection molding process. Long carbon fiber is a relatively high cost material, and need to evaluate the cost performance problem in the selection process. 3. The cost of long fiber products is higher.

PEEK introduce PEEK can also be called polyether ether ketone, as a high-performance semi-crystalline plastics, such plastics have excellent chemical resistance, mechanical strength, dimensional stability and a series of good performance, according to the performance is divided into a variety of series of materials, the most common classification of PEEK materials are PEEK pure material, glass fiber or carbon fiber modification. PEEK Pure Material We can see that with an elongation at break of 15%, PEEK Pure, despite its high toughness, has a modulus of elasticity of only 4,200mpa, the lowest in the family of plastics. This relatively low modulus means that PEEK pure is 'softer' and less abrasion resistant than other PEEK modifiers. Therefore, if you are using PEEK pure in frictional working conditions, be aware of material loss due to wear of the material. PEEK filling Long Carbon Fiber Material PEEK LCF30 is a 30% longer carbon fiber filled plastic based on PEEK pure material, the carbon fibers increase the modulus compared to PEEK pure material while maintaining maximum toughness of the material PEEK CF30 is a material that maintains a very high level of stiffness and relatively high toughness. In addition, long carbon fiber modified PEEK exhibits excellent wear resistance and very good friction properties. PEEK LCF30 has better wear resistance compared to PEEK LGF30. Long carbon fibers conduct heat more efficiently. PEEK LCF30 is therefore suitable for sliding applications. Like PEEK pure resins, PEEK LCF30 has excellent hydrolysis resistance in steam and boiling water. The difference between LCF and SCF Staple fiber can also be called cut section fiber, staple fiber is obtained mainly by cutting off the chemical long fibers into a section of short fibers, so that the fibers formed are about the same length as natural fibers. Under normal circumstances, between 35-150 mm is called the length of staple fiber. In the composite material made of fiber is cut or pulled, the fiber is pulled from the matrix, such a pulling process is conducive to the absorption of energy provided by the loading, in a certain length range of the fiber, the longer the fiber, the greater the absorption of energy, and its strength is also more significant. And in the same volume amount, due to the longer the single fiber, the fewer the number of fiber roots, the less stress concentration generated at the fiber end, the more difficult the destruction of the material. From the results of the feedback of practical applications, the long carbon fiber reinforced thermoplastic composites of 6mm-24mm have more excellent various properties than the short fibers. In addition, carbon fiber reinforced composites in the friction process, the fiber body plays an important role in lubrication, long distance carbon fiber can be much more sustainable, stable lubrication, so the coefficient of friction is lower, less wear, and the formation of finer abrasive debris. Due to such advantages, long carbon fiber reinforced thermoplastic composites are not afraid of high frequencies and loads, and perform much better in practical applications. Application of PEEK-LCF materials

Throughout the plastics industry, PEEK is widely recognized as a leading high performance polymer (HPP). However, the preferred material in the automotive, aerospace, oil and gas, and medical device industries has long been metal, and PEEK polymers are rapidly changing that mindset. What is the PEEK material PEEK or Polyetheretherketone belongs to the class of polymers known as "aromatic polyketones" (more accurately Polyaryletherketone or PAEK). Research and development of PEEK began in the 1960s, but it wasn't until 1978 that Imperial Chemical Industries (ICI) patented PEEK, and Victrex PEEK polymer was first commercialized in 1981. "Aromatic" usually implies a distinctive or sweet flavor, which may seem like an odd term, but scientists use it to describe certain molecules that contain or consist of a cyclic structure (such as the aryl unit above). Small molecules of this type, such as toluene and naphthalene, have distinctive odors and hence the name. However, PEEK itself, like most thermoplastics, is odorless under normal conditions. Chemically, PEEK is primarily a linear semi-crystalline polymer. P comes from the Greek word "poly" meaning "many", so many EEKs form PEEK. aryl and ketone groups provide stiffness by being somewhat rigid, which means good mechanical properties and a high melting point. The ether group provides a degree of flexibility, while the aryl and ketone groups are chemically inert and thus chemically resistant. The regular structure of the repeating units means that the PEEK molecule can be partially crystallized and the crystallinity provides properties such as wear resistance, creep resistance, fatigue resistance and chemical resistance. The resulting polymer is widely recognized as one of the best performing thermoplastics in the world. Compared to metals, PEEK-like materials are lightweight, easy to mold, corrosion-resistant, and have a fairly high specific strength (strength per weight). Datasheet for reference When high performance is required, PEEK as the polymer of choice offers more than just two or three properties, it offers a wide range of excellent properties including: - High heat resistance Testing has shown that LFT-G's PEEK polymer has a continuous use temperature of 260°C (500°F). This allows for a wide range of applications in hot corrosive environments such as the process industry, oil and gas industry, and the engines and transmissions of countless vehicles.PEEK resists friction and wear in dynamic applications such as thrust washers and seals. - Chemically Inert PEEK resists damage caused by chemically corrosive working environments such as downhole environments in the oil and gas industry, and gears in mechanical and automotive applications. It is resistant to jet fuels, hydraulic fluids, de-icers and pesticides used in the aerospace industry for a wide range of pressures, temperatures and time frames. - Strong mechanical properties PEEK exhibits excellent strength and stiffness over a wide range of temperatures, and the specific strength of PEEK-like carbon fiber composites is many times higher than that of metals and alloys. "Creep" is the permanent deformation of a material under constant stress over a period of time. "Fatigue" is the brittle destruction of a material under repeated cyclic loading. Because of its semi-crystalline structure, PEEK has high creep and fatigue resistance and is more durable than many other polymers and metals over a long service life. - Does not ignite or burn easily PEEK has excellent flame resistance, with an ignition temperature of nearly 600°C. Even when ignited at very high temperatures, it does not burn continuously and emits little smoke. This is one of the reasons why PEEK is widely used in commercial aircraft. - Reprocessable and recyclable PEEK molecules are so stable that they can be melted and reprocessed time and time again with minimal impact on their properties. This helps to improve the environmental footprint and ensures more efficient reuse of waste materials generated during the manufacturing process. - And there's more! PEEK is also non-hygroscopic, so its properties are not altered in wet environments; it is resistant to gamma and electron beam radiation and is transparent under X-ray exposure, making it attractive for medical device applications.PEEK is also electrically stable and is typically used as an electrical insulator, but can be modified to become a conductor or static dissipative material. As a thermoplastic PEEK, it can be injection molded, compression molded and extruded using conventional thermoplastic processing equipment. It is very versatile and its use is becoming more and more common to improve component performance, durability, reduce weight and lower overall system costs over its lifetime. There is no doubt that it is replacing metals and alloys. In many industries and critical environments, material specialists, part designers and buyers must choose between PEEK and traditional metals a...

PEEK-Long carbon fiber Polyetheretherketone (PEEK), the complete English name for polyetheretherketone, is a specialty engineering plastic with excellent performance, and has more advantages than other specialty engineering plastics, such as wear resistance, high temperature resistance, high strength and high modulus, flame retardant and radiation resistant, and so on. In addition polyetheretherketone (PEEK) has good thermal stability and melt flow above the melting point, so polyetheretherketone (PEEK) also has the typical processing properties of thermoplastics. PEEK resin is nontoxic, lightweight, corrosion-resistant, and one of the closest materials to the human skeleton, which is well compatible with the musculature, so it is often used instead of metal to make human bones. Carbon fiber-reinforced PEEK composites make up for the weaknesses of toughness and deviations in impact strength. Carbon fiber-reinforced PEEK composites can exhibit high mechanical strength and hydrolytic stability under conditions such as hot water, steam, solvents, and chemical reagents, and can be used to prepare various medical devices that require high-temperature steam sterilization. Advantages of PEEK-LCF PEEK has high rigidity, good dimensional stability, low coefficient of linear expansion, and can withstand great stress without significant elongation over time, and its low density and good processing properties make it suitable for parts with high requirements for fineness. Among these elements, carbon fiber materials overlap highly with the characteristics of PEEK. Carbon fiber is not only one of the typical lightweight materials, it is also outstanding in terms of mechanical properties. As a result, carbon fiber reinforced PEEK composites can reduce weight by at least 70% compared to traditional metal materials. PEEK material itself is very wear-resistant, and good interface bonding with carbon fibers to further enhance its wear resistance, through the carbon fiber reinforced PEEK composite parts and cobalt alloy materials for wear comparison experiments, the results show that: at 23 ℃, using the M-200 wear machine at 400 rpm after 100 minutes of wear, found that the carbon fiber reinforced PEEK composite surface smooth The wear marks were small, and the carbon fiber bonded well with PEEK without fiber extraction.

What are the types of thermoplastic carbon fiber composites? Carbon fiber thermoplastic composites are composites with carbon fiber as the reinforcing material and thermoplastic resin as the matrix. From the reinforcement method of carbon fiber, it can be divided into long-cut carbon fiber (LCF) reinforced thermoplastic composites, short-cut carbon fiber (SCF) reinforced thermoplastic composites and continuous carbon fiber (CCF) reinforced thermoplastic composites. Long-cut carbon fiber and short-cut carbon fiber mainly refer to the application length of carbon fiber materials, there is no strict fixed distinction between the two, generally between a few millimeters to a few centimeters, the more common specifications are 6mm, 12mm, 20mm, 30mm, 50mm. Carbon fiber thermoplastic composites can also be classified according to the thermoplastic resin. There are many common thermoplastic resins, such as PE, PP, PVC, etc. However, thermoplastic resin composites with carbon fiber reinforcement are mostly used in aerospace, precision equipment and other demanding working environments, therefore, carbon fiber thermoplastic composites are more often made of polyether ether ketone (PEEK), PPS, polyimide ( PI), polyetherimide (PAI) and other mid- to high-end thermoplastic resins as the matrix to achieve the optimization of material performance. 2. How does thermoplastic carbon fiber composite material achieve low cost and environmental protection? Thermoplastic carbon fiber composites are used to make parts for high-end machinery. They have excellent machinability, vacuum forming, stamping mold plasticity, and bending processability. For example, Teijin has been able to add a recycling process to the process according to specific needs, and to shred and mold the corners of thermoplastic carbon fiber composite materials after stamping to make recycled materials for making small products or for molding nuts and studs on carbon fiber prototypes. This method can greatly reduce the loss of raw materials, improve the efficiency of the use of thermoplastic carbon fiber composite materials, reduce the overall cost, and thus achieve the purpose of environmental protection. In addition, thermoplastic carbon fiber composites can reduce the molding cycle time compared with thermoset carbon fiber composi...
