纤维增强复合材料疲劳性能的温度效应
TEMPERATURE EFFECT ON FATIGUE PERFORMANCE OF FIBER-REINFORCED POLYMER
摘要
Abstract
Fiber Reinforced Polymer (FRP) has attracted much attention due to its high strength to weight ratio,strong resistance to chemical corrosion,while its anti-fatigue property varies with material characteristics,ambient environmental conditions and loading status.In this study,the performance of FRP on anti-fatigue was studied under different temperatures and loading stress level according to the phenomenology-based macro mechanical theories,and an equivalent model was proposed to estimate and predict the stiffness degradation and residue fatigue life of FRP under the synergy effect of temperature and fatigue stress level.Based on the experimental data,the verification of the model was carried out.The verified model was applied to predict the fatigue performance of the E-glass plainweave fabric laminate.It is shown that the suggested model may efficiently predict the stiffness degradation and equivalent residue fatigue life of FRP.The temperature effect on fatigue property of FRP is obvious and this effect may even be more evident than that of the stress amplitude for FRP.关键词
