▎ 摘　　要

NOVELTY - A ceramic-based brake pad composite material comprises ceramic matrix with curved-hole flow channel ceramics, 1-1.5 wt.% graphene, 2-4 wt.% tin-silver-copper alloy, 2-4 wt.% nitrile rubber powder, and composite filler comprising 2-5 wt.% linseed-modified phenolic resin. USE - Ceramic-based brake pad composite material. ADVANTAGE - The average friction coefficient of brake pad material changes steadily and is greater than 0.402, and material wear rate is lower than 1.15x 10-7 cm3.N-1.m-1, so that the parameters of the material meets the national standard. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of ceramic-based brake pad composite material, which involves preparing ceramic substrate with curved-hole flow channel by light curing molding technology, filling mixed composite filler into the curved-hole flow channel of the ceramic matrix by vacuum pressure infiltration technology and hot-press molding.
