Abstract

The invention relates to a foamed ceramic reinforced light metal composite friction clutch disc and brake disc. The brake disc comprises a metal base body, the metal base body is provided with one or two friction surface layers, and the friction surface layers are foamed ceramic reinforced light metal composite friction surface layers. According to the brake disc, the characteristics that industrial ceramic is high in hardness, high in wear resistance and resistant to high temperature are given full play to, the characteristics that light metal is light in weight, high in strength and good in toughness are given full play to, the industrial ceramic is made into foamed ceramic with the topological geometric structure through the proper technology, and then the foamed ceramic is combined with the light metal to be made into the novel friction clutch disc and brake disc with the characteristics of the foamed ceramic and the light metal. The clutch disc and brake disc can meet the friction engagement and brake requirements of moving machinery equipment such as airplanes, rail transit vehicles, road traffic vehicles and ships.

Description

technical field [0001] The invention relates to a foam ceramic reinforced light metal composite friction clutch plate and a brake disc, which belong to the field of friction clutch plates and brakes. Background technique [0002] With the rapid development of modern aerospace, high-speed railway, highway traffic and wind power generation, more and more attention has been paid to the weight, safety, vibration and noise of friction clutch plates and brake systems. Especially under high-speed and heavy-duty conditions, without affecting the performance of the friction clutch and braking system, the requirements for weight reduction, shock absorption, noise reduction, safety, comfort and wear resistance of the friction clutch and braking system are getting higher and higher. come higher. Some new materials with integrated functions and structures have attracted the attention of scholars at home and abroad because of their remarkable shock absorption, noise reduction, light weig...
