| 摘 要： | 研究了芳纶浆粕含量和摩擦温度对制动摩擦材料摩擦性能的影响,并应用可拓评价方法对芳纶浆粕增强制动摩擦材料的摩擦系数和磨损率进行了可拓评价。结果表明,5种制动摩擦材料都具有较好耐磨性,且芳纶的加入进一步改善了摩擦材料的耐磨性;5个试样按照计算所得综合关联度的优劣排序为:T-3.4,T-0,T-14.6,T-5.6,和T-9.0(数字代表芳纶浆粕在配方中的体积分数),且芳纶浆粕体积分数为3.4%时该摩擦材料的摩擦系数和磨损率的综合效果最好。

| Abstract: | The effects of aramid pulp content and friction temperature on the friction performance of non-asbestos organic brake friction composites have been investigated.Based on the merit of extenics,the extension evaluation method was applied to assess the overall quality of five different friction composites.Five brake friction materials with different aramid pulp contents were evaluated and their performance,expressed as the weighted average dependent degree in the extension evaluation,placed in order from best to worst,as follows:3.4% aramid pulp content>0%>14.6%>5.6%>9.0%. |
