摘　　要：研究Kevlar对位芳纶浆粕和精切短纤维对天然橡胶胶料的补强效果。结果表明:随着纤维用量的增大,Kevlar对位芳纶浆粕补强的胶料储能模量增加幅度大于损耗模量增加幅度,损耗角和损耗因子随着浆粕用量的增大而降低,这种效果有利于低滚动阻力轮胎或其他轮胎部件的胶料配方设计,在提高胶料定伸模量的同时不会增加滞后生热;Kevlar对位芳纶浆粕表现出的一种独特手风琴效应可能是低滞后生热的原因。The reinforcing effect of Kevlar rubber compound were investigated. The results para-aramid pulp and floc short fiber on the natural showed that, as the addition level of fiber increased, the increase in storage modulus of Kevlar para-aramid pulp reinforced rubber was greater than that in loss modulus;the loss angle and loss factor decreased as the addition level of pulp reduced. This effect was desired in tire component formulation and low rolling resistance tires design, since the tensile modulus increased without increasing hysteresis heat build-up. This unique behavior of low hysteresis heat build-up at increasing modulus may be attributed to the ＂accordion＂ effect Kevlar para-aramid pulp.
