A Study on the High Temperature Performance of the Brake Materials Built in Korean Model Combat Vehicle

한국형 기동장비 마찰재의 고온성능 연구

Organic brake materials are installed in the braking system of korean model combat vehicles. Since the binder resin is decomposed in high temperature region, it may possible to drop the friction force which makes the vehicle stop within the desired distance. This study analyses the braking performance of the brake materials in high temperature region by using the pin-on-disk type friction tester. It is observed radical drop of friction coefficients and rapid increase of wear amounts from the transition temperature. It is due to the formation of oxide layer on the friction surface.
