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-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. Se prepararon composites PEEK/CF de diferentes longitudes mediante moldeo por inyección y se estudiaron sus propiedades infiltrantes y tribológicas. Los resultados muestran que la adición de CF aumenta el ángulo de contacto y disminuye la hidrofilia de los compuestos. Pero el coeficiente de fricción de los materiales compuestos se reduce y se mejora la resistencia a la fricción. La fibra de carbono larga (LCF) tiene un mejor efecto en la reducción del coeficiente de fricción que la fibra de carbono corta (SCF).
