| 中文摘要: |
| 采用原位改性针状硅酸盐（FS）和芳纶短切纤维(DCAF)与氢化丁腈橡胶（HNBR）机械共混制备HNBR/DCAF/FS复合材料，研究DCAF用量、长度和FS用量对复合材料结构与性能的影响。结果表明，加入DCAF能显著提高复合材料小应变下的定伸应力和压缩模量，增大DCAF长度和用量有利于改善复合材料的拉伸性能及其各向异性；加入FS能明显改善复合材料的拉伸应力 应变特性，提高复合材料的压缩模量。 |
| 英文摘要: |
| HNBR/short aramid fiber(DCAF)/fibrillar silicate(FS) composites were prepared by mechanical blending of in situ modified FS，DCAF and HNBR.The effects of the addition levels of DCAF and FS，and different lengths of DCAF on the structure and properties of the composites were investigated.The results showed that the moduli of the composites under both tension and compression conditions at small strain were increased by adding DCAF；the tensile properties and anisotropy of the composites could be improved when the length or addition levels of DCAF increased；the stress strain behavior and compression modulus of the composites were improved significantly by adding FS. |
