| 中文摘要: |
| 研究短纤维/白炭黑补强溶聚丁苯橡胶（SSBR）复合材料的结构与性能。结果表明：与无短纤维胶料相比，短纤维胶料的t10均延长，t90无明显变化，FL和Fmax均降低，在短纤维胶料中非极性的聚酯短纤维和芳纶短纤维胶料的FL和Fmax较高；芳纶短纤维胶料的门尼粘度较高，聚酯短纤维和芳纶短纤维胶料硬度较大；聚酯短纤维胶料的拉伸强度较大，取向程度较高，芳纶短纤维胶料的撕裂强度较大；芳纶短纤维补强SSBR胶料在拉伸速率达到400 mm·min-1后发生屈服，屈服软化后发产生塑性形变；短纤维/白炭黑补强SSBR胶料断裂破坏的主要机理是短纤维-短纤维、橡胶-白炭黑之间相互作用力的破坏，破坏形态以短纤维的抽出为主。 |
| 英文摘要: |
| The structure and properties of short fiber/silica reinforced solution polymerized styrene - butadiene rubber（SSBR） composites were studied. The results showed that t10 of the compound with short fiber was prolonged，t90 had no obvious change，and FL and Fmax were reduced compared with that of the compound without short fiber. The FL and Fmax of the compounds with non-polar polyester short fiber and aramid short fiber were higher among the compounds with short fiber. The Mooney viscosity of the compound with aramid short fiber was high，and the hardness of the vulcanizates with polyester short fiber and aramid short fiber were high. The tensile strength of the vulcanizates with polyester short fiber was high while the fiber orientation degree was high，and the vulcanizates with aramid short fiber possessed high tear strength. SSBR vulcanizate with aramid short fiber showed yielding and plastic deformation when the tensile rate reached 400 mm·min-1. The main mechanisms of the failure of fiber/silica reinforced SSBR rubber were the destructions of the interaction between short fiber and short fiber，and between rubber matrix and silica. The failure mode was dominated by pull-out of short fiber. |
