摘　　要：以新疆乙烯焦油为原料,制备改性沥青,通过熔融纺丝、不熔化、炭化等工艺制备沥青基炭纤维。利用TG、DSC、SEM等手段,对石油沥青纤维在空气中的不熔化处理进行了研究,并研究不熔化条件对炭纤维微观结构及拉伸强度的影响,分析皮芯结构的形成,以及不熔化过程中张力对纤维拉伸强度的影响。In the paper,the thermal-modification pitch was prepared by Xinjiang ethylene tar.Carbon fibers are obtained by melt-spin,oxidative stabilization and carbonization.The DSC,TG,SEM was employed to investigate the pitch fibers＇ oxidative process in the air condition.We investigate the effect on tensile strength of oxidative stabilization conditions of carbon fiber.We study skin-core structure of the formation and investigate tensile strength and microstructure which are influenced oxidative process tension on the fiber.

关 键 词：沥青纤维 不熔化 拉伸强度
