摘　　要：为提高国产高模量碳纤维的拉伸性能,研究国产CCM40J,CCM55J碳纤维在浸胶前后加捻两种方式下的拉伸强度与断裂伸长率。结果显示:加捻可以有效改善CCM40J与CCM55J碳纤维的拉伸性能;与CCM55J碳纤维相比,当捻度为10 n/m时,浸胶后加捻的CCM40J碳纤维拉伸强度与断裂伸长率均提高17%;为改善两种高模量碳纤维的拉伸性能,确定了最佳捻度与浸胶方式。In order to improve the tensile properties of high modulus carbon fibers,the tensile strength and elongation at break of CCM40J and CCM55J carbon fibers before and after resin dipping were studied.It is found that twisting can improve the tensile properties of carbon fiber.Compared with CCM55J carbon fiber,the tensile strength and elongation at break of CCM40J carbon fiber increased by 17%when the twisting was 10 n/m.In order to improve the tensile properties of two high modulus carbon fibers,the optimal twist and dipping method were determined.
