| 摘 要： | 采用综合性能优异的氢化丁腈橡胶(HNBR)和耐高温对位芳纶短纤维复合,制备了高强度、高模量和耐高温的复合材料,比较了芳纶短纤维类型、纤维用量等对复合材料力学性能和流变行为的影响。结果表明,芳纶浆粕(PPTA-pulp)比芳纶短切纤维(DCF)对橡胶有更佳的增强效果,二者都能明显提高HNBR的高温强度,但PPTA-pulp的效果更为明显。PPTA-pulp增强橡胶复合材料的挤出物外观性能也较DCF增强橡胶复合材料好。 |

| Abstract: | Hydrogenated nitrile-butadiene rubber with excellent comprehensive properties was reinforced by-powered para aramid. The composites showed high tensile strength, high modulus and high temperature resistance. Mechanical and rheological properties influenced by kinds and contents of fibers were researched. It was proved that aramid pulp ( PPTA-pulp) had better effect on reinforcing the composites than dipped chopped fibers(DCF). They were both elevating the high temperature strength of composites, but PPTA-pulp was more effective. More over, extrudate of the composites reinforced by PPTA-pulp was more smooth than that of DCF. |
| Keywords: | para aramid short fiber hydrogenated nitrile-butadiene rubber high temperature resistance |
