摘　　要：用声速法(SV)、差示扫描量热法(DSC)、大角X射线衍射法(WAXD)等研究了PAN预氧化纤维的柔性与原丝基体,预氧化反应条件之间的关东。结果表明,OF的柔性与原丝性质、预氧化反应程度、预氧丝取向度密切相关,而与预氧化反应速度无关。试验还确定了获得最佳柔性的OF的氧化程度。The relationship Was studied between the flexibility of Pan-base preoxidized fibre (pan-of) and its precurser fibre, as well as the conditions of preoxidized reaction by means of SV,DSC and WAXD, etc. The result shows that flexibility of pan-of is in close relation withprecurser fibre properties,orientation of preoxidized fibre and degree of preoxidized reaction,but is independent of rate of preoxidized reaction. In our studies the degree of preoxidizedreaction which gives the pan-of optimum flexibility can be ascertained.
