摘要
碳纤维增强树脂复合材料(CFRP)是高性能结构的先进材料。通过试验,对纤维增强树脂复合材料(FRP)损伤理论的定义进行了研究,论述了用于CFRP层合板疲劳累积损伤的剩余强度模型和剩余刚度模型。通过理论预测与实验数据比较,证明所建模型物理意义清晰,数据吻合较好,最后对两种模型进行了分析和比较。
Carbon fibre reinforced composite laminates is a type of high quality and advanced material. In this paper according the experiment, we study the definition of the damage theory on FRP, and discuss the model of the residual strength and residual stiffness about CRRP. According the comparing of the theory forecasting and experiment data, the model is in focus and the data is very connected. At last we analyze and compare the two models.
