废短纤维/橡胶复合材料的力学和疲劳性能

考察了橡胶再生废短纤维的表面特性和长度分布，研究了橡胶再生废短纤维／橡胶复合材料（ＷＳＦＲＣ）的力学性能以及纤维表面预处理对它的影响，探讨了它在橡胶工业中应用的可能性。对ＷＳ－ＦＲＣ的动态拉伸和压缩疲劳性能也进行了考察。结果表明：随着纤维用量的增加．ＷＳＦＲＣ的拉伸和压缩疲劳性能下降；与同样硬度的纯炭黑胶料相比，ＷＳＦＲＣ的疲劳温升更低；ＷＳＦＲＣ的疲劳性能还随纤维排列方向的不同而变化。

Mechanical Properties and Fatigue Endurance of Waste Short Fiber/Rubber Composite

The surface characteristics and the length distribution of the waste short fiber from reclaimed rubber were investigated. The mechanical properties of WSFRC (the waste short fiber/rubber composite)and the influence of the surface treatment of waste short fiber on them were studied. The potential applications of WSFRC to the rubber industry were discussed. The fatigue endurance of WSFRC was measured through the dynamic extension and compression test. The results showed that the extension and compression fatigue endurance decreased as the short fiber level increased; the fatigue temperature rise of WSFRC was lower than that of conventional black compound with the same hardness; the fatigue endurance of WSFRC varied with the orientation of short fiber.
