Abstract

The invention discloses a ceramic fiber reinforced resin-based brake pad mixed material capable of reducing brake disc cracks. According to the invention, the brake pad material which is small in abrasion to a brake disc, capable of reducing the crack failure rate of the brake disc, energy-saving and environment-friendly is realized. In order to prevent a large amount of hydrogen from being diffused to the surface of a brake drum in the braking process, a hydrogen binding additive B is added into the brake pad mixed material for reducing the brake disc cracks. Another method is to prevent hydrogen diffusion by forming a layer of transfer film on the surface of the brake disc as a barrier. A transfer film hydrogen additive E is certainly added into the brake pad mixed material for reducing the drum crack to form a nano-scale transfer film on a friction surface as a barrier, so that diffusion of hydrogen is prevented; due to the design breakthrough and introduction of the transfer film technology in the formula, the abrasion of the brake pad, the abrasion of the brake disc and the cracks of the brake disc are effectively reduced.

Description

Technical field [0001] The present invention belongs to the field of production technology of the wear material, and is specifically a ceramic fiber reinforced resin-based brake blade mixing material which reduces the brake disc. Background technique [0002] During the braking of the brakes, the organic brake pads and the brake disc of the cast iron are slidable. At higher friction temperatures, the thermal degradation and chemical reactions of organic matter, hydrogen from the organic resin, causing the brake pad surface to occur in the surface of the brake pad. Hydrogen diffuses to the surface of the cast iron, causing an increase in hydrogen concentration, and it is very easy to grow the hydrogen concentration to generate a "hydrogenamb" in the critical concentration (saturated state). When the surface temperature of the brake disc is in the range of 200 to 600 ° C, the reaction between hydrogen and iron carbide can be observed. The result of the reaction is methane and iron,...
