摘　　要：为了提升亚麻短纤维增强硅橡胶复合材料的力学性能,以亚麻短纤维作增强体,硅橡胶为基体,制备了亚麻短纤维/硅橡胶复合材料。研究了亚麻短纤维的长度和用量对复合材料拉伸弹性模量的影响。结果表明,不同长度和用量的亚麻短纤维对硅橡胶基复合材料的补强作用不同;当亚麻短纤维的体积分数为1.26%、长度为2.5 mm时,复合材料的拉伸弹性模量最高,断裂应变最低。工业生产中,可以通过控制亚麻短纤维的长度和含量对硅橡胶基体进行补强达到不同的效果。In order to improve the mechanical properties of short flax fiber reinforced silicone rubber composites,flax short fiber/silicone rubber composite was prepared with flax short fiber as reinforcement and silicone rubber as matrix.The effects of the length and content of flax short fiber on the tensile elastic modulus of composites were studied.The results show that the reinforcing effect of flax short fibers with different length and content on silicone-rubber-matrix composites is different.The tensile elastic modulus of the composite is the highest and breaking strain is the lowest when the content of flax short fibers is 1.26%and the length of flax short fiber is 2.5 mm.In the process of industrial production,different effects can be achieved by controlling the length and content of flax short fiber to reinforce the silicone rubber matrix.
