【摘要】 通过实践深入探讨了聚丙烯腈原丝生产的聚合机理,并借助于SEM对所纺的碳纤维原丝进行了探讨,实验证明,生产原丝中的聚合机理遵循4个阶段,而且聚合温度没有超过聚丙烯腈的分解温度。纺丝要控制预牵伸倍数在7左右,为蒸汽牵伸提高原丝的取向度和结晶度以及最终碳纤维的高性能作好准备。更多还原

【Abstract】 This paper discusses the copolymering mechanism based on practical experience,and,using results from an SEM analysis, also discusses the spinning process. The experiment shows that copolymering included four stages,and the copolymering temperature was below the decomposing temperature. A drawing stretch ratio of about seven was selected in order to make high performance precursor and optimum property carbon fiber.更多还原
