摘要

对本实验室直接缩聚法制备的芳纶浆粕以及传统的纺丝切割法制备的Kevlar浆粕和Twaron浆粕取代石棉在酚醛树脂基摩擦材料中的摩擦性能进行了研究.结果表明，3种芳纶浆粕增强的摩擦材料都具有优良的摩擦磨损性能，特别是随着温度升高，摩擦系数有较大提高的同时，磨损率明显下降，克服了石棉增强的摩擦材料在较高温度下磨损率较大的缺点.直接缩聚法制备的PPTA浆粕增强的摩擦材料摩擦性能与Kevlar浆粕和Twaron浆粕增强的相近，为芳纶浆粕增强摩擦材料的国产化奠定了基础.

Abstract

As the replacement of asbestos reinforced friction materials

poly-p-phenylene terephthalamide(PPTA) pulps have attracted wide attention. In this paper

the frictional properties of Kevlar pulps

Twaron pulps and the PPTA pulps manufactured by direct polycondensation in the authors’lab were investigated. The result showed that the compounds reinforced by these PPTA pulps all had excellent friction and wear properties. With the increase of temperature

the friction coefficient of the composition materials increased and the wear rate of the composition materials decreased.PPTA pulps in the friction materials overcome the shortcoming of asbestos that has high wear rate at high temperature.The frictional properties of the self made PPTA pulps were very close to those of Kevlar and Twaron pulps.There are good prospects in domestic production of friction materials reinforced by PPTA pulps.
