▎ 摘　　要

NOVELTY - Carbon/ceramic brake disc with sandwich structure comprises friction function layer, a mechanical function layer and a friction function layer, which are connected by mortise and tenon and specifically comprising carbon cloth composite layer, short fiber layer, the carbon cloth composite layer is by mold pressing the sandwich structure substrate through high temperature cracking, and silicon infiltration reaction is prepared, the carbon cloth composite layer is multi layers of pre-impregnated carbon cloth overlapped, the short fiber layer is made of chopped carbon fiber, resin and additive is prepared by short fiber premix, the density of the sandwich structure matrix is 1.2-1.7 g/cm3, the density of the carbon/ceramic brake disc of sandwich structure is 2-2.5g/cm3, the additive is graphite powder, carbon powder, silicon powder, silicon carbide powder, boron powder, copper powder, iron powder, silicon dioxide powder, graphene, magnesium stearate and hexamethylene tetramine. USE - The carbon/ceramic brake disc with sandwich structure is useful for vehicle brake parts, namely high speed train, high grade roadster, and racing car. ADVANTAGE - The brake disc: has excellent integral mechanical property, friction wear resistance and long service life, and through solid environment mold pressing, cracking, infiltration preparation, simple preparation process, short production period and economical. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the process diagram of preparing carbon/ceramic brake disc with sandwich structure. (Drawing includes non-English language text).
