本文在我校固体为学教研室自行设计研制的摆锤式单杆冲击拉伸试验装置上对用作复合材料基体的环氧树脂和不鲍和聚脂的动态力学性能进行实验研究,对试件的断口进行了电镜观察和分析,得到了在不同应变率下拉伸的应为应变关系和有关结果;进而讨论了这两种基体材料对复合材料动态力学性能的影响,同时提出了设计抗冲击的结构复合材料应遵循纤维和基体的动态最大应变匹配原则。 In this paper, the dynamic mechanical properties of epoxy resin and non-abalone polyester used as the matrix of composite material were experimentally studied on the pendulum-type single rod impact tensile test device designed and developed by our school for solid science research department. Of the fracture were observed and analyzed by electron microscopy, obtained at different strain rates should be strain relationship and related results; and then discussed the two matrix materials on the dynamic mechanical properties of composites, while the design of the impact of the design The structural composites should follow the dynamic maximum strain matching principle of fibers and matrix.
