The brake pad comprises a steel sheet and a friction block, and the friction block is prepared from boron-modified phenolic resin, organic silicone-modified phenolic resin, barium phenolic resin, phenylacetylene phenolic resin, epoxy-terminated liquid reaction type nitrile rubber, butadiene rubber, molybdenum disulfide, sisal fiber, bamboo carbon fiber, aluminum fiber, molybdenum fiber, poly-p-phenylene benzodioxazole fiber, zinc oxide crystal whiskers, montmorillonite, vermiculite, nanometer aluminum oxide, cerium oxide, zirconium boride, aluminum silicate hollow spheres, graphene oxide, copper powder, carbon nano tubes, nano carbon black, butadiene styrene rubber powder, ammonium molybdate and octaphenyl silsesquioxane. The brake pad made of the composite material is high in high temperature resistance, excellent in heat stability, high in abrasion resistance and long in service life.

Description

technical field [0001] The invention relates to the technical field of brake pads, in particular to a composite material brake pad. Background technique [0002] With the rapid growth of China's automobile production and sales, the level of China's automobile manufacturing and technology has also been steadily developed and improved. It is also a good opportunity and challenge for auto parts suppliers with independent intellectual property rights and research and development capabilities. Brake pads are one of the most common parts in automobiles. They are composed of steel sheets and friction substrates attached to the steel sheets. They are the most critical safety parts. Brake pads play a decisive role in all braking effects. However, the strength of the existing friction materials for brake pads is low, and the thermal stability is poor when the friction generates high temperature, and some raw materials are easily oxidized when the high temperature is generated, result...
