聚丙烯腈基炭纤维对比分析:(二)结构与性能的关联性
A comparative analysis of polyacrylonitrile-based carbon fibers:(Ⅱ) Relationship between the microstructures and properties
摘要
Abstract
The relationships between the mechanical properties and the microstructures of typical polyacrylonitrile-based carbon fi-bers were studied on the basis of the elastic wrinkle model and Griffith microcrack theory. The effects of microcrystallite structure and its preferred orientation on tensile modulus, the effects of microvoids and mass density changes on the tensile strength, and the effects of internal residual compressive stress on the strain to failure, were analyzed, based on which the structural factors played a key role in determining the mechanical properties of the fibers.关键词
