Carbon ceramic aircraft brakedisc

2022-02-09

Carbon-ceramic brake disc is a new generation of aircraft brake material after carbon-carbon brake disc. The carbon-ceramic aircraft brake disc has good strength and toughness, high static friction coefficient and low wet state attenuation, and solves the problems of serious wet friction performance attenuation and low static friction coefficient of the carbon/carbon aircraft brake disc. The production cycle is 2/3 lower than the carbon/carbon ratio, the production cost is reduced by 1/3, and the energy consumption is reduced by 2/3, which is very competitive. In terms of braking system, compared with CCCSiC brake disc (commonly known as carbon-ceramic brake disc) has the advantages of short cycle, low cost, high strength, high static friction coefficient, and basic dynamic and static friction coefficient under wet/salt fog. Significant advantages such as no attenuation.

The addition of zirconium silicide(ZrSi2)can increase the wear resistance and high temperature resistance of the material. The mass fraction of zirconium disilicide is 10-15%. Adding this mass fraction of zirconium disilicide to the ceramic matrix composite material can significantly reduce the material preparation. sintering temperature.
