New fiber material friction disc - carbon fiber friction disc
Let me introduce you to a new type of fiber material friction plate, which is carbon fiber friction plate. It is a fibrous material friction plate formed by heating organic fiber or low molecular hydrocarbon gas raw material to 1500 ℃, with a carbon content of more than 90%. Because carbon fiber has the inherent nature of carbon materials, it also has the electrical and thermal conductivity of metal friction plates, the heat resistance and corrosion resistance of ceramic materials, the softness and knitability of textile fibers, and the light weight and easy processing properties of polymer materials. , is a multi-functional and multi-purpose functional and structural material. Therefore, it is widely used in aerospace, aviation, military industry, automobile, medical, chemical industry, cultural and sporting goods and other fields.
According to the classification of raw materials, carbon fiber can be divided into polyacrylonitrile-based carbon fiber friction pads, pitch-based carbon fiber friction pads, adhesive-based carbon fiber friction pads and phenolic resin carbon fiber friction pads. At present, it is mainly polyacrylonitrile-based carbon fiber friction plate and pitch-based carbon fiber friction plate, and there are few other carbon fibers. Pitch-based carbon fiber friction plates are divided into two types: general-purpose pitch-based carbon fiber and high-performance pitch-based carbon fiber.
Carbon fiber has the following excellent properties: Light specific gravity; High specific modulus; Excellent physical and mechanical properties such as wear resistance, fatigue resistance, vibration reduction and energy absorption; Resistant to acid, alkali and salt corrosion, and can form porous and highly surface active activated carbon fibers; Thermal expansion coefficient Small, good thermal conductivity; performance does not decline in high temperature environments; has lubricity and does not wet in molten metal, which can reduce the wear rate; such excellent characteristics show great development and application prospects in the field of friction materials, carbon fiber The use of friction materials has greatly improved the comprehensive performance of friction materials and friction plates. It is often added to resin, metal or ceramics, carbon, cement and other matrices to form carbon fiber reinforced composite friction plates. It is an extremely useful structural material for friction. piece.
