摘要:

将短切碳纤维（CF）、白炭黑和甲基乙烯基硅橡胶（VMQ）共混后，与碳纤维布（CFC）复合制备VMQ复合材料。考察了CFC层数对复合材料的拉伸性能、邵尔A硬度、耐磨性能及动态力学性能的影响。结果表明，随着CFC层数的增加，复合材料的扯断伸长率基本不变，拉伸强度逐渐升高。与仅添加10份（质量，下同）CF的复合材料相比，加入10份CF及4层CFC的复合材料的拉伸强度提高了409%。各复合材料的摩擦系数相差较小，与未添加CF及CFC的试样相比，加入10份CF及3层CFC的复合材料磨损量增加了168%。VMQ复合材料的损耗因子随着频率的升高而增大，与未加入CF及CFC的试样相比，仅添加10份CF的VMQ复合材料的损耗因子由0.120增大到0.151。

Abstract:

Methyl vinyl silicone rubber (VMQ) composites were prepared by blending chopped carbon fiber (CF), silica and VMQ with carbon fiber cloth (CFC). The effects of the layer number of CFC on the tensile properties, Shore A hardness, wear resistance and dynamic mechanical properties of the composites were investigated. The results showed that the elongation at break of the composites was basically unchanged and the tensile strength increased with the increasing layer number of CFC. Compared with the composites with only 10 phr (mass,the same below)of CF, the tensile strength of the composites with 10 phr of CF and 4 layers of CFC increased by 409%. The friction coefficients of the composites had little difference. And compared with the samples without CF and CFC, the wear of the composites with 10 phr of CF and 3 layers of CFC increased by 168%. The loss factor of VMQ compo-sites increased with increasing frequency. Compared with the samples without CF and CFC, the loss factor of VMQ composites with 10 phr CF only increased from 0.120 to 0.151.
