摘要
设计并制备了含生物质黄麻纤维和榛子壳粉的新型环境友好型摩擦材料。用CHASE摩擦试验机测定了材料的摩擦性能,用可拓方法对摩擦试验结果进行了评价。摩擦试验结果表明,当鼓温低于黄麻纤维的分解温度时,黄麻纤维具有降低和稳定摩擦系数的作用;当鼓温接近于黄麻纤维的分解温度时,摩擦材料出现热衰退。为了保证摩擦材料在高温的摩擦性能,黄麻纤维的含量不应过高。黄麻纤维的加入可以降低摩擦材料的磨损率。可拓评价结果表明,当黄麻纤维体积分数为9.0%时具有最大的关联度,综合摩擦性能最好。
A new type of eco-friendly friction material containing biomass jute fibers and hazelnut shell powder has been prepared.A chase friction tester was used to determine the friction performance of the materials.The friction performance was evaluated using an extension evaluation method（EEM） and the formulation was optimized.The friction test results showed that jute fibers can stabilize and decrease the friction coefficient when the temperature of the iron drum was lower than the thermal decomposition temperature（Td） of jute fibers,but if the volume content of jute fibers was too high the friction properties could not be maintained at high temperature.Both thickness and weight wear rates decreased significantly after the addition of jute fibers.The EEM results showed that the optimum amount of jute,which gave the best friction performance,was 9.0%.
