Carbon fiber is made from organic matrix fibers (such as viscose, polyacrylonitrile or asphalt) by pyrolysis under inert gas at a high temperature of 1000-3000 degrees.
The result is the removal of all elements except carbon.
Carbon fiber has stability, electrical conductivity, self-lubricating property, unparalleled reinforcement, and can be compounded with resin, plastic, metal, rubber and other materials to increase the strength and wear resistance of the material.
Carbon fiber powder, also called milled carbon fiber, is an equal-length cylindrical particle obtained by surface treatment of high-strength and high-modulus carbon fiber filaments through special technology, grinding, microscopic screening, screening, and high-temperature drying. It retains many excellent properties of carbon fiber. , and the shape is small, the surface is pure, the specific surface area is large, and it is easy to be wetted and dispersed by the resin. It is a composite material filler with excellent performance. It can be compounded with resin, plastic, metal, rubber and other materials to increase the strength and wear resistance of the material.
The application of carbon fiber powder finished products in civil engineering mainly includes fiber cloth, fiberboard, bar, profile, short fiber, etc. The disk of an electronic computer made of carbon fiber can increase the storage capacity and computing speed of the computer. It can be used as an aircraft structure material, electromagnetic shielding material, artificial ligament and other body substitute materials, as well as for the manufacture of rocket shells, motor ships, industrial robots, Automobile leaf springs and drive shafts, etc.
