Abstract

The invention discloses a high heat load tolerant frictional material. The frictional material is prepared from the following components in parts by weight: 15-35 parts of resin, 15-30 parts of composite fibers, 5-20 parts of polyimide, 5-15 parts of barium sulfate, 1-2 parts of wollastonite and 1-2 parts of aluminum oxide. The frictional material can bear a high heat load and is stable in frictional coefficient in a high-temperature environment and relatively low in wear rate, thereby having excellent heat attenuation resistance.

Description

technical field [0001] The invention relates to the field of special materials, in particular to a friction material withstanding high heat load. Background technique [0002] People have higher and higher requirements for the performance of friction materials used in brakes and clutches such as disc brakes and drum brakes. Existing friction materials generally have good friction performance at room temperature, but in high temperature environments Or under continuous working conditions, the coefficient of friction cannot be kept constant, which will cause problems such as slipping. [0003] Therefore, prior art also needs further development and improvement. Contents of the invention [0004] The purpose of the present invention is to provide a high thermal load-resistant friction material, aiming to solve the problem that the current friction plate materials are not resistant to high thermal load. [0005] Technical scheme of the present invention is as follows: [00...
