Abstract:

Decomposition products of asbestos friction material are carcinogenic and have severe pollution on the environment. In order to develop new ono-asbestos friction materials, glass fiber fabric which has excellent mechanical properties compared with asbestos was used as substrate, and phenolic resin was used as curing agent, By molding and curing, the friction material products were prepared. The influence of curing temperature, curing time, fiber orientation and phenolic resin on the tribological properties of glass fiber composite was studied in this paper. The results show that the optimum condition is curing time of 1 h and curing temperature of 180°C. Under this condition, the wear rate of the composite is the lowest with a friction coefficient of 0.25. The friction and wear properties of the glass fiber composite meet the application requirements. Furthermore, it can be widely used in various fields due to the advantages of low-cost, environmental friendiness, good heat resistance and mechanical strength.
