摘    要:研究了纸浆纤维与Kevlar纤维浆粕混杂纤维中纸浆纤维的含量对其压缩回弹性能的影响,评价了不同比压和转速条件下纸基摩擦材料的摩擦磨损性能,分析了材料的压缩回弹性能与摩擦性能的关系.结果表明,纸浆纤维含量对压缩率和回弹率影响不明显,但随着加载压力增加,材料的压缩率和回弹率明显增大.在相同比压和转速条件下,纸浆纤维含量对纸基摩擦材料动摩擦系数的影响不明显,但随着比压和转速的增加,纸基摩擦材料的摩擦系数降低,其中含有17.5%纸浆纤维的纸基材料在循环制动条件下的摩擦系数最稳定,磨损率最低.

关 键 词:纸基摩擦材料  混杂纤维  压缩回弹性能  摩擦磨损性能

Abstract: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.
Keywords:paper based friction material  hybrid fiber  compressure-resilience  friction and wear behavior
