聚丙烯腈纤维对汽车摩擦材料性能的影响
在一种成熟低金属配方基础上,采用热压法制备聚丙烯腈纤维增强摩擦材料,研究聚丙烯腈纤维含量对摩擦材料物理性能、力学性能、摩擦磨损性能及制动噪音的影响。结果表明：随聚丙烯腈纤维含量增加,摩擦材料的密度逐渐降低,而气孔率、压缩变形量和内剪切强度先升高然后降低;添加聚丙烯腈纤维对名义摩擦因数的影响较小,但会降低材料的抗高温衰退性能,并且随着其含量的增多,摩擦因数的衰退幅度增大;添加聚丙烯腈纤维会提高材料的磨损率,并随其含量的增加呈现先降低后略有增加的趋势;添加适量的聚丙烯腈纤维有利于抑制噪音的产生,在质量分数为3%~5%左右时,噪音表现最佳。...

| Abstract_FL | The PAN (Polyacrylonitrile)fiber enhanced friction materials were prepared by hot-press method based on a low metal formula,and the influences of PAN fiber content on the physical per-formance mechanical property,friction and wear properties and brake noise of the friction materials were investigated.The results show that as the PAN fiber content increase,the density decrease,and the porosity,shear strength and compress deflection of the friction material increase firstly then de-crease;adding PAN fiber to the friction material has little influence on the nominal friction coefficient, but will reduce the anti-high temperature wear performance,and as the content increases,the friction coefficient increases;however,adding PAN fiber will improve the friction and wear rate of materials, but with the PAN fiber content increasing,friction and wear rate exhibits the tendency of decreasing firstly and then slightly increasing;adding adequate PAN fiber is conducive to the suppression of noise generation,when the PAN fiber content is about 3%-5%,the noise performance is the best. |
