Background
At present, the brake materials widely applied to high-speed trains, racing cars and airplanes mainly adopt powder metallurgy materials and carbon-carbon composite materials. Compared with steel brakes, the brake made of carbon-carbon composite material has the advantages of light weight, wear resistance, high specific heat, no adhesion at high temperature and the like. However, in the traditional manufacturing method of the carbon-based brake disc, a carbon blank is manufactured by adopting a CVD (chemical vapor deposition) method, and the carbon blank is manufactured into a carbon blank by needling a plurality of carbon fiber cloth layers. In the use process, the friction surface of the brake disc has unequal friction, so that the surface of the brake disc is uneven, a large amount of fibers remain, the shaking of a vehicle body and the dynamic balance can not be maintained during braking, in addition, the production period is long through a CVD vapor deposition method, and the development of the method is restricted. The Chinese patent application CN 105697614A is an airplane carbon-carbon composite brake disc and a manufacturing method thereof, the airplane carbon-carbon composite brake disc is formed by continuously and circumferentially winding carbon fiber cloth or polyacrylonitrile carbon fiber felt or a composite layer formed by overlapping the carbon fiber cloth and the carbon fiber felt together, and compounding a carbon fiber wire which radially penetrates through the winding layer and a carbon matrix, and the airplane carbon-carbon composite brake disc is obtained through a densification process and subsequent treatment. The orientation of the fibers of the carbon disk, either parallel to the friction surface, perpendicular to the friction surface, or at an angle to the friction surface, facilitates stabilization and improved frictional wear performance. The brake pad changes the state that the fibers of the traditional carbon cloth plane laminated carbon disk are all in parallel friction surfaces, and has the characteristics of long service life and good comprehensive performance of the carbon disk. However, in the manufacturing process of the brake disc, the densification is performed by adopting a single impregnation method, a CVD method process or a composite process combining the impregnation method and the CVD method, the production and processing time is relatively long, and the cost is high.
