本文从应力诱导结晶和应力活化反应速度理论出发,提出了等速拉伸下自增强高聚物抗张强度动力学模型理论,推导出了等速加力和等速形变下自增强高聚物极限断裂方程。它们成功地把抗张强度同成型工艺参数、测试条件、起始高聚物非晶区中的伸直链分数、起始分子量及其分布等联系起来。这些定量关系式为研究自增强高聚物抗张强度同成型工艺和测试条件以及其起始结构间的关系建立了理论基础。
In this paper a new model theory of tensile strength for self-reinforced polymerswas derived from the theory of stress-induced crystallization and of chemical reaction rate acti-vated by stress.A new correlation between the tensile strength with the proce
