摘　　要：研究了由聚丙烯腈原丝制备碳纤维的连续预氧化过程中纤维张力的变化以及对最终碳纤维结构及力学性能的影响。实验结果表明:预氧化阶段纤维张力主要取决于外加拉伸比及纤维的物化行为。此阶段施加较高的拉伸比,纤维张力则较大,并同时提高了碳纤维微晶取向和力学性能。The effect of the change of fiber tention on the structure and mechanical propertyof the finished product carbon fiber produced from PAN precursor fiber was studied. The results show that the fiber tention during pre-oxidation is mainlydepend on the drawing ratio imposed and the physicochemical behavior. With higherdrawing ratio, the fiber tention increases and the microcrystalline orientation andmechanical property of carbon fiber are improved.
