PPS Special engineering plastics are engineering plastics with higher overall performance and long-term use temperature above 150℃, PPS is one of them. The carbon fiber reinforced special engineering composites formed by carbon fiber as the reinforcement and these special engineering plastics as the matrix have excellent mechanical properties, wear resistance and high temperature resistance, which can be used in aerospace, marine or medical fields, and in some aspects show more desirable application advantages than thermosetting resins or even metal materials. PPS-LCF Polyphenylene sulfide PPS resin strength and hardness are relatively high, good mechanical properties, adapt to a variety of molding and processing methods, you can achieve secondary precision molding, the dimensional stability of the product is better. Its moisture absorption rate of only 0.03%, low density, melt temperature Tm of 285 ℃, the glass transition temperature Tg of 90 ℃, thermal stability is very good, in the air state, to reach 430 ℃ -460 ℃ before decomposition, high flame retardant grade, 200 ℃ insoluble in most organic solvents, excellent electrical insulation. As a special engineering plastics, PPS advantages are outstanding, but defects also exist, for example, because of the large number of benzene ring to make its impact resistance and elongation is not good enough, but through the carbon fiber reinforced way, can further improve the performance of the material strength and thermal stability, so as to better show the value of the application of the material. Through the carbon fiber reinforced intervention, changing the original insulating properties of PPS into a conductive, anti-static properties, polyphenylene sulfide PPS toughness and strength can be substantially increased and improved, becoming one of the most commonly used composite materials in the aerospace field. It is used in aircraft landing gear, wings, hatches, fuel tank port covers, J-shaped nose cone, cabin interior trim and other components, not only to help increase the impact resistance, high temperature and corrosion resistance of these parts, more through the reduction in mass, to enhance the aircraft load efficiency and reduce fuel consumption. Compared with metal, this composite material has the advantages of low cost and easy processing, the cost can be reduced by 20-50 percent. High bonding must be maintained between the carbon fiber reinforcement and the PPS resin matrix. When the product is subjected to stress, this high bonding helps the interface to transfer the external load to the fibers effectively, which can effectively prevent cracks from debonding between the interfaces, in addition to enhancing the mechanical properties of the composite. To make the resin matrix and carbon fiber reinforcement between the formation of high bonding, we must make the molten state of PPS resin and carbon fiber reinforcement in full contact, full impregnation, so that the fiber body in the case of uniform dispersion to achieve good impregnation effect.

PPS Information Polyphenylene sulfide (PPS) is not enhanced before modification, its disadvantages are brittle, poor toughness, low impact strength, after filling glass fiber, carbon fiber and other enhancements modified to overcome the above shortcomings, to obtain very good overall performance. PPS filling Long carbon fiber In the modified engineering plastics industry, long fiber reinforced composites are composites made from long carbon fibers, long glass fibers and polymer matrix through a series of special modification methods. The most important feature of long fiber composites is that they have superior performance that the original materials do not have. If we classify them according to the length of the reinforcing materials added, they can be divided into: long fiber, short fiber and continuous fiber composites. Long carbon fiber composites are one kind of long fiber reinforced composites, which are a new fiber material with high strength and high modulus. It is a new material with excellent mechanical properties and many special functions. Corrosion resistance: LCF carbon fiber composite materials have good corrosion resistance and can adapt to the harsh working environment. UV resistance: the ability to resist UV is strong, and the products are less damaged by UV. Abrasion and impact resistance: the advantage of comparing with general materials is more obvious. Low density: lower density than many metal materials, can achieve the purpose of light weight. Other properties: such as reducing warpage, improving rigidity, impact modification, increasing toughness, electrical conductivity, etc. LCF carbon fiber composites have higher strength, higher rigidity, lower weight, and excellent electrical conductivity compared with glass fiber.

The price of carbon fiber composite products is closely related to the price of raw materials, the level of technology and the number of products. The higher the performance of the raw material, the more expensive it is, such as the carbon fiber PEEK thermoplastic material used in orthopedics. Of course, the more complex the manufacturing process, the greater the working time and workload, and the increased production costs. However, the larger the order quantity, the lower the cost per product. In the long run, the superior performance of carbon fiber will extend the life of the product, reduce the number of maintenance, and is also very beneficial to reduce the cost of use. 2. Are carbon fiber composite products toxic? Carbon fiber composites are made of carbon fiber filaments mixed with ceramics, resins, metals and other substrates, and are generally not toxic. For example, the above-mentioned PEEK material is made of food-grade resin, which is very compatible with the human body and is not only harmless to humans, but also becomes a more ideal material for orthopedic surgery because of its high strength and elastic modulus close to the bone cortex. Carbon fiber medical bed plate, will be in daily contact with many patients body, will not have adverse effects on the human body, on the contrary, for the accuracy of medical diagnosis and a great help. 3. What is the difference between thermosetting carbon fiber composites and thermoplastic carbon fiber composites? Thermoset carbon fiber composites favor the role of curing agent in curing and molding. While thermoplastic carbon fiber composite products mainly rely on cooling down to achieve the shaping. Thermoplastic carbon fiber composites are not as popular as thermoset carbon fiber composites, mainly because they are expensive and are generally used in high-end industries. Thermoset carbon fiber composites are difficult to recycle due to the limitation of the resin matrix itself, and are generally not considered; thermoplastic carbon fiber composites can be recycled, and can be made twice as long as they are heated to a certain temperature.

PPS material In recent years, the application of special engineering plastics has gradually extended from the previous military and aerospace fields to more and more civil fields, such as automotive, equipment manufacturing, high-end consumer goods, etc.. Among them, polyphenylene sulfide (PPS) and polyether ether ketone (PEEK) are two special engineering plastics that have developed relatively quickly and have a wide range of applications. PEEK is superior to PPS in terms of strength, toughness, and maximum operating temperature. In terms of high-temperature resistance, PEEK is about 50°C higher than PPS. But on the other hand, the relatively obvious cost advantages and better processing properties of PPS make it more widely used. PPS is a crystalline, highly rigid white powder polymer, high heat resistance (long-term use of 200 ℃ -220 ℃, short-term can withstand high temperatures of 260 ℃), is a mechanical strength, rigidity, flame retardant, chemical resistance, electrical properties, dimensional stability are excellent resin. It has excellent wear resistance, creep resistance, flame retardancy and self-extinguishing properties. It maintains good electrical properties at high temperature and high humidity. Good flowability, easy to mold, almost no shrinkage and concave spot when molding. Good affinity with various inorganic fillers. It has been developed to shorten the difference between standard thermoplastic materials (e.g. PA, POM, PET ......) and advanced engineering plastics. PPS has the following distinct performance advantages: (1) Intrinsically Flame Retardant Unlike PC and PA, PPS pure resin and its glass fiber/mineral powder filled composites without any added flame retardants 可以轻松达到V-0@0.8mm甚至更薄厚度的V-0阻燃级别. Although PC and PA have a cheaper price and better mechanical strength (especially impact strength) than PPS, the cost of PC and PA composites with the addition of halogen-free flame retardant formulations (V-0@0.8mm级别) is significantly higher, in many cases even higher than PPS materials with the same mechanical strength. (2) Ultra-high flowability For the semi-crystalline PPS, its very high fluidity can allow glass fiber filling easily more than 50 %, while in the process of high-temperature melt blending extrusion, PPS compared to PC lower viscosity can make the glass fiber to withstand a lower degree of shear and extrusion, so that the final injection molded products have a longer retention length, to further enhance the effect of modulus. (3) Ultra-low water absorption This advantage is mainly for PA. In terms of fluidity, highly filled PA and PPS are comparable; and for mechanical properties, the same amount of filling PA composites will be more advantageous. But in addition to the halogen-free flame retardant limitations, another factor limiting the application of PA is its high water absorption: compared to high-temperature nylon PA6T 0.6%-1% water absorption, PPS 0.03% water absorption rate is almost negligible. The result is that PPS products due to water absorption and deformation of the product defect rate is much lower than the same conditions of PA products. (4) the unique metallic texture and higher surface hardness PPS injection molded parts will be dropped on the table, a very crisp sound unique to PPS crash. Through the special mold and reasonable mold temperature with the PPS injection molded parts in the human touch will also sound similar to the impact of metal, the surface will be as smooth as a mirror, with a metal-like luster. PPS-LCF compounds Length: About 12mm, or customized Color: Original color, or customized Fiber specification: 20%-60% Grade: General grade Long carbon fiber reinforced composites offer significant weight savings and provide optimum strength and stiffness properties in reinforced thermoplastics. The excellent mechanical properties of long carbon fiber reinforced composites make it an ideal replacement for metals. Combined with the design and manufacturing advantages of injection molded thermoplastics, long carbon fiber composites simplify the re-imagining of compoents and equipment with demanding performance requirements. Its widespread use in aerospace and other advanced industrials makes it a "high-tech" perception of consumers. Datasheet for reference Application Factory Q & A 1. Is there a uniform reference data for carbon fiber product performance? The performance of specific carbon fiber filaments is fixed, such as Toray's carbon fiber filaments, T300, T300J, T400, T700, etc. There are a series of parameters that can be traced. However, there is no uniform standard to measure the carbon fiber composite products. Firstly, the different models of raw materials selected will lead to different performance of the products, and then the different selection of substrate and product design will lead to different performance of the products. In addition to some common carbon fiber tube, carbon fiber plate and other conventional parts, most of th...
