用于制造碳纤维的特殊等级的聚丙烯腈母体纤维在预稳定阶段通过不同程度的拉伸进行改性。监测这种拉伸对原始前体纤维、中间体（氧化）纤维和通过连续工艺制备的所得碳纤维的拉伸性能的影响。随着拉伸比的增加，观察到不同阶段纤维拉伸模量的改善。然而，没有发现最终碳纤维的拉伸强度有明显的提高。 (C) 1994 约翰威利父子公司
Polyacrylonitrile precursor fiber of a special grade for making carbon fibers was modified by stretching in the prestabilization stage to various extents. The effect of such stretching on tensile properties of the original precursor fiber, intermediate (oxidized) fiber, and resultant carbon fiber prepared through a continuous process was monitored. Improvements in tensile modulus of fibers at various stages were observed with increasing stretch ratios. However, no obvious enhancement of tensile strength of final carbon fibers was found.
