A Study of Compressure-resilience and Tribology Properties of Hybrid Fiber Reinforced Paper-based Friction Materials

Compressure-resilience and tribology properties of hybrid fiber reinforced paper-based friction materials were investigated. Influence of content of kraft fiber on properties of the paper-based friction materials was discussed. The results show that influence of content of kraft fiber on compressure-resilience and tribology properties was inapparent, however the compressure rate and resilient rate were increased when pressure was increased, and friction coefficient was decreased to some extent when pressure and rotate speed were increased. Sample containing 17.5% kraft fiber exhibited the most stable friction coefficient and the lowest wear rate under repeating brake.
