摘要
对环氧树脂及其改性后树脂的低温静态和动态的断裂性能进行了分析 ,并对增韧机制进行了相应的研究。得到环氧树脂及其增韧树脂在低温情况下的断口特征以及在低温情况下裂纹快速扩展的特征。文中还分析了材料在低温时快速扩展的机制 。
In this paper, the static and dynamic fracture properties of epoxy and toughened epoxy resins and the low temperature were studied. The section characters of these resins were obtained by electron micrograph. The mechanism of rapid crack propogation was analysed. The result shows lwo temperature fracture toughness of toughened epoxy resins can be improved.
