  • Abstract:研究了短纤维用量和黏合水平、测试温度及频率对溶聚丁苯橡胶(SSBR)/炭黑/短纤维复合材料(SFRC)动态力学性能的影响。结果表明,SFRC的储能模量(E′)随短纤维用量的增加而增大;填充预处理短纤维的SFRC的E′大于填充同种未处理短纤维的SFRC,损耗因子(tanδ)则是后者大于前者(填充20份尼龙短纤维的SFRC除外)。与相同填充量的纯炭黑硫化胶相比,短纤维部分取代炭黑后,硫化胶在大于15℃时的E′增大(填充未处理聚酯短纤维的SFRC除外),tanδ减小;SFRC的E′和tanδ随频率的增加而增大,但频率为50~100 Hz时,随着温度的升高,短纤维用量越高,SFRC的E′减小,且E′和tanδ受频率的影响越小。
