Abstract:

选用国产的连续炭纤维长丝与ABS树脂分别采用常规共混法、薄膜层叠法、溶液浸渍法三种工艺制备了连续炭纤维增强ABS热塑性树脂复合材料。通过对复合材料的力学性能、热性能、动态黏弹性及微观形貌的研究,分析了ABS热塑性树脂基复合材料的制备工艺对界面性能的影响。结果表明不同制备工艺中复合材料随炭纤维含量的增加其各项力学性能都不断提高,当炭纤维含量为60%(质量分数)时力学性能达到最高,但不同制备工艺导致复合材料界面性能差异较大,影响其力学性能的增幅。溶液浸渍法制备的复合材料树脂对炭纤维的浸润性良好,其最大拉伸强度和层间剪切强度分别达到1100MPa和71MPa,较常规共混法复合材料性能提高约80%;其损耗角正切仅为常规共混法复合材料的40%;界面性能提高使复合材料的耐热性能提高。
