单向聚酯帘线/橡胶复合材料的疲劳损伤机理 刘宇艳 万志敏 田振辉 杜星文 摘要:利用软X射线技术和扫描电子显微镜技术,研究了在周期载荷下单向聚酯帘线/橡胶复合材料的疲劳机理。结果表明,在高应力下,单向聚酯帘线/橡胶复合材料的疲劳损伤以聚酯帘线断裂为主;在中应力下,单向聚酯帘线/橡胶复合材料的疲劳损伤是逐步进行的;在低应力下,单向聚酯帘线/橡胶复合材料的疲劳损伤仅有局部的界面损伤。 Fatigue damage mechanism of unidirectional polyester cord/ rubber composites under cyclic loading Liu Yuyan Wan Zhimin Tian Zhenhui and Du Xingwen Abstract:The fatigue damage mechanism of unidirectional polyester
reinforced rubber composites was studied with soft X-ray radiography and scanning
electron microscopy under cyclic loading.The results showed that the damage of rubber
composites in form of fiber failure was observed at high cyclic stress level,the fatigue
damage of rubber composites was progressively developed at medium cyclic stress and at low
cyclic stress level only local interfacial failure was seen. 基金项目:哈尔滨工业大学基金资助项目。 参 考 文 献 : 1,Math N M,Bhowmick A K,De S K.Chemical and
