What is PA6? Nylon6 (PA6), also known as polyamide 6, English name: Polyamide6 or Nylon6, PA6 for short; That is, polycaprolactam, obtained from caprolactam ring-opening polycondensation. It is translucent or opaque opalescent resin, with superior mechanical properties, stiffness, toughness, wear resistance and mechanical shock absorption, good insulation and chemical resistance. Widely used in automotive parts, electronic and electrical parts and other fields. What are the advantages and disadvantages of PA6? Main advantages of PA: 1. High mechanical strength, good toughness, high tensile and compressive strength. 2. outstanding fatigue resistance, parts after repeated bending can still maintain the original mechanical strength. 3. high softening point, heat resistant. 4. smooth surface, small friction coefficient, wear-resistant. 5. corrosion resistance, very alkali and most salts, also resistant to weak acid, oil, gasoline, aromatic compounds and general solvents, aromatic compounds are inert, but not resistant to strong acids and oxidants. 6. with self-extinguishing, non-toxic, odorless, good weather resistance. 7. Excellent electrical performance. Good electrical insulation, nylon volume resistance is high, high breakdown voltage resistance, in dry environment, can be used as power frequency insulation material, even in high humidity environment still has good electrical insulation. 8. light weight, easy to dye, easy to form. Main disadvantages of PA: 1. easy to absorb water. High water absorption, saturated water can reach more than 3%. The dimensional stability and electrical properties are affected to some extent, especially the thickening of thin-walled parts. Water absorption also greatly reduces the mechanical strength of plastics. 2. Poor light resistance. In a long-term high temperature environment, it will oxidize with oxygen in the air, turn brown at the beginning, and then break and crack. 3. injection molding technology requirements are more strict: the existence of trace moisture will cause great damage to the quality of molding; The dimensional stability of the product is difficult to control because of thermal expansion. The existence of sharp Angle in the product will lead to stress concentration and reduce the mechanical strength; If the wall thickness is not uniform, it will lead to the distortion and deformation of the parts. High precision of equipment is required in post-processing. 4. will absorb water, alcohol and swelling, not resistant to strong acid and oxidant, can not be used as acid-resistant materials. There are many advantages of PA6, but also many disadvantages, these disadvantages limit the play of the advantages, so people thought of modifying methods to enhance its application.

Carbon Fiber Reinforced Plastic Carbon fiber reinforced plastic composite (CFRP) is a lightweight, strong material that can be used to make a wide range of products used in everyday life. It is a term used to describe fiber reinforced composites with carbon fiber as the main structural component. Note that the "P" in CFRP can also stand for "plastic" rather than "polymer." Typically, CFRP composites use thermosetting resins such as epoxy, polyester, or vinyl esters. Despite the use of thermoplastic resins in CFRP composites, "carbon fiber reinforced thermoplastic composites" often uses its own acronym, CFRTP composites. LFT-G focuses on LFT&LFRT. Long Glass Fiber Series (LGF) & Long Carbon Fiber Series. Compared with Short Carbon Fiber, Long Carbon Fiber has more excellent performance in mechanical properties. It is  more suitable for large products and structural parts. It has 1-3 times higher (toughness) than Short Carbon Fiber, and the tensile strength(strength and rigidity) is increased by 0.5-1 times. Properties of CFRP composites Composites reinforced with carbon fiber are different from other FRP composites that use traditional materials such as glass fiber or arylon fiber. Advantages of CFRP composites include: Light weight: Conventional fiberglass reinforced composites using continuous fiberglass and 70% fiberglass (glass weight/gross weight) typically have a density of 0.065 lb/cubic inch. A CFRP composite with the same 70% fiber weight might typically have a density of 0.055 lb/cubic inch. Increased strength: Carbon fiber composites not only weigh less, but CFRP composites are stronger and stiffer per unit weight. This is true when comparing carbon fiber composites to glass fibers, and even more so when comparing metals. For example, when comparing steel to CFRP composites, a good rule of thumb is that a carbon fiber structure of the same strength typically weighs 1/5 as steel. You can imagine why car companies are looking into using carbon fiber instead of steel. When comparing CFRP composites to aluminum (one of the lightest metals used), the standard assumption is that an aluminum structure of the same strength might weigh 1.5 times as much as a carbon fiber structure. Of course, there are many variables that can change this comparison. Grades and qualities of materials may vary, and for composites, the manufacturing process, fiber structure and quality need to be considered. Disadvantages of CFRP composites Cost: As amazing as the material is, there's a reason carbon fiber can't be used in every situation. Currently, the cost of CFRP composites is too high in many cases. Depending on current market conditions (supply and demand), the type of carbon fiber (aerospace grade versus commercial grade), and bundle size, carbon fiber prices can vary significantly. On a per-pound basis, carbon fiber can cost anywhere from five to 25 times more than fiberglass. The difference is even greater when comparing steel with CFRP composites. Electrical conductivity: This can be a plus or minus for carbon fiber composites, depending on the application. Carbon fiber is extremely conductive, while glass fiber is insulating. Many applications use fiberglass instead of carbon fiber or metal, strictly because of electrical conductivity. For example, in the utility industry, many products require the use of fiberglass. This is one of the reasons why the ladder uses fiberglass as the ladder rail. The chance of electric shock is much lower if the fiberglass ladder comes into contact with the power cord. The situation with CFRP ladders is different. Although the cost of CFRP composites remains high, new technological advances in manufacturing are continuing to provide more cost effective products. Application of PP-LCF Long Carbon Fiber as the reinforcement material of CFRP, its proportion is only 1/4 of iron, specific strength is 10 times that of iron, elastic modulus is 7 times that of iron, carbon fiber excellent physical properties are played in various fields from sports goods to aircraft.

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-LCF? 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 for reference Application Q&A 1. What are the advantages of long carbon fiber materials?

PA66 Nylon (PA) has a series of excellent properties, such as high mechanical strength, chemical resistance, oil resistance, wear resistance, self-lubrication, easy processing and forming, and has become one of the thermoplastic engineering plastics widely used at home and abroad. But in the practical application, the performance requirements of nylon are different under different conditions or environment. For example, electric drill and motor shell, pump impeller, bearing, diesel engine and air conditioning fan and other parts require nylon material to have high strength, high rigidity and high dimensional stability; Because of the poor toughness of nylon at low temperature, it is necessary to toughen it. In some outdoor applications, nylon materials must be weather-resistant modification in long-term outdoor environment. PA66-LCF Long carbon fiber reinforced nylon has excellent damping properties in 3D printing and has better performance than glass fiber reinforced nylon. In the design of tools for industrial applications, traditional techniques have used aluminum or alternative metal alloys because metal components perform better and meet the requirements of the tool. In many cases, thermoplastics can meet the strength requirements of such tools, but not the rigidity requirements for performing test tasks. Carbon fiber reinforced nylon is an ideal substitute for metal. Due to the combination of the light weight of nylon and the mechanical strength and thermal properties of carbon fiber, the strength and stiffness of carbon fiber composite nylon material is significantly improved, and its mechanical strength even exceeds that of 3D-printed PEEK and PEKK. In the automobile industry, from internal and external components such as vehicle anchors and instruments to engine housing, metal parts can be replaced. As we all know, automotive carbon fiber is widely used in automobile manufacturing due to its strong thermal and mechanical properties. As a substitute for metal parts, carbon fiber reinforced nylon has a wide range of application prospects in the automobile industry, which can realize the possibility of weight reduction and design optimization, as well as environmental protection and economic advantages.

Long Carbon Fiber In recent years, due to the growing demand for lightweight in various industries around the world (automotive, aerospace, military, building and civil engineering, etc.), and the increasingly strict requirements for the use of environmentally friendly and sustainable materials, the use of fiber reinforced thermoplastic composites in various industries has been increasing. Especially for carbon fiber reinforced composites, there is still a high recycling value after the products are discarded after completing their life cycle, and through effective recycling technology and methods, the cost of carbon fiber reinforced composites can be significantly reduced. The recovery method of fiber reinforced thermoplastic composites is closely related to the shape and forming method of fiber reinforced in resin. Take carbon fiber reinforced thermoplastic composites as an example. The reinforced forms of carbon fiber mainly include short fiber reinforced, long fiber reinforced and continuous fiber reinforced, and the main preparation method is melt forming. For thermoplastic resins with high melting point, such as polyetherimide (PEI) and polyetherether ketone (PEEK), solvent forming can be adopted. Due to the linear molecular structure of thermoplastic resin, it is easy to transform from solid state to liquid state at high temperature. Therefore, thermoplastic composite materials can be recycled by remelting and reshaping method, which is more recyclable than thermosetting resin matrix composite materials.

PLA-LCF Polylactic acid or PLA is a bio-based polymer made using lactic acid from the sugar fermentation process. It was originally intended as a more environmentally friendly alternative to crude oil-based polymers and is technically biodegradable (albeit under industrial compost conditions). In addition to being the most widely used polymer in the desktop 3D printing space, PLA also has a variety of applications in packaging, disposable cups and more. Although it is very cost effective, easy to process and easy to 3D print, pure PLA has poor thermal and mechanical stability and is therefore not suitable for any high performance applications. One way to improve material properties is to use additives such as carbon fiber reinforced materials, as carbon fiber composites can provide an excellent mix of mechanical properties and heat resistance. Long carbon fiber reinforced PLA is an outstanding material that is strong, lightweight, has excellent layer bonding and low warpage. It has excellent layer adhesion and low warpage. Long carbon fiber PLA is stronger than other 3D-printed materials. Long carbon fiber filaments are not as strong as other 3D materials, but tougher. The increased rigidity of carbon fiber means increased structural support but reduced overall flexibility. It is slightly more brittle than regular PLA. When printed, the material is a dark glossy color that shimmers slightly under direct light. characteristic The fracture strain is moderate (8-10%), so the silk is not brittle, but strong toughness Very high melt strength and viscosity Good dimensional accuracy and stability Easy to handle on many platforms High attractive matte black surface Excellent impact resistance and lightness Application of long carbon fiber filliing PLA material Long carbon fiber filling PLA is an ideal material for frames, braces, shells, propellers, tools, instruments, etc. Virtually no bending will occur.
