摘　　要：以碳纤维、对位芳纶短切纤维和芳纶浆粕为纸基摩擦材料的增强纤维,在湿法成形过程中添加海泡石绒和阳离子聚丙烯酰胺(CPAM),探究它们对填料留着率的影响,并通过扫描电子显微镜(SEM)的观察研究及其吸附和粘结作用的机理。实验研究表明:在海泡石绒用量10%、CPAM用量0.24%时,可以显著提高纤维和填料的留着率。Carbon fiber, aramid short fiber and Kedar pulp reinforced paper-based friction material, adding sepiolite and cationic polyacrylamide（CPAM） in the wet forming process to study the influence of the retention rate and mechanism of adsorption and bonding, qhe experimental study showed that when CPAM dosage 0.24%, the content of sepiolite 10%, can significantly improve the pulp and filler retention. At the same time, the sepiolite and CPAM retention mechanism was studied by SEM.
