本文研究了有增强和无增强的两种热固性聚合物材料的蠕变性质,用光学方法观测了试样在蠕变过程中的微损伤活动,记录了材料在蠕变过程中的微损伤曲线,推出了材料的线性弹滞极限应变值。同时,本文从材料的微观结构出发,讨论了微损伤的产生原因及其发展规律。最后,还说明了材料的工艺加工条件对微损伤活动的影响。 In this paper, the creep properties of two thermosetting polymer materials with and without reinforcement were investigated. The micro-damage activities of the samples during creep process were observed by optical method. The micro-damage curves of the materials during creep process were recorded. Introduced the linear bounce limit strain of the material. At the same time, starting from the microstructure of the material, this paper discusses the causes of micro-damage and its development. Finally, the effect of material processing conditions on micro-damage activities is also illustrated.
