研究短纤维取向度和取向角对短纤维/天然橡胶复合材料性能的影响.结果表明:短纤维取向度和取向角越大,在该方向上复合材料综合性能越好,并且表现出了各向异性的特性;短纤维胶料流动性较差,基质变形受到很大限制.通过建立实验系统实现了对短纤维取向的定性表征.%The effects of orientation and orientation angle of short fiber on the properties of short fiber/NR composites were investigated.The qualitative characterization of the short fiber orientation was established and the testing results showed that,when the orientation degree and orientation angle of short fibers increased,the composite exhibited anisotropic characteristics and the properties along the orientation direction were improved.It was found that the fluidity of short fiber reinforced compound was poor,and the matrix deformation was greatly limited by short fibers.
