Short basalt fiber （BF）/silicone rubber composites were prepared by using BF as reinforcer.The effects of the variety of silane coupling agent,the amount of BF and the curing conditions on mechanical properties of the composites were investigated,and the micromorphology of the composites was analyzed by scanning electron microscope.The results showed that the mechanical properties of the composites,in which BF surface was treated with silane coupling agent KH 550,were better than those with Si 69.When the amount of BF was 20 phr and the curing conditions were 175 ℃ × 10 MPa × 25 min,the mechanical properties of BF/silicone rubber composites were the best.Treated with KH 550,BF had the better compatibility with silicone rubber than treated with Si 69.
