碳纤维增强环氧树脂复合材料的紫外老化及寿命预测
UV Aging and Life Prediction of Carbon Fiber Reinforced Epoxy Resin Composites
摘要
Abstract
The carbon fiber reinforced epoxy resin-based laminates(CFREL)were prepared using hot press tank molding process.The laminates were subjected to UV aging experiments under different temperature cycles through an artificial accelerated aging test,and the mechanical properties of the specimens were evaluated at different temperatures and times intervals and the microscopic morphology was observed by scanning electron microscope(SEM).Studying the bending strength and interlaminar shear strength of CFREL subjected to UV aging.The life prediction was based on the residual strength model and the kinetic curve model.The results show that the calculated life prediction model aligns well with the experimental results,and the service life of the CFREL under natural light can be calculated with different strength retention rates.关键词
