Using accelerated aging, the GFRP laminates were exposed to UV radiation for a certain period of time under outdoor conditions, and then the residual strength was measured. At the same time, by analyzing the fiber direction, filling materials and layers in GFRP laminates, a residual strength prediction model was established, and its accuracy was verified.Through experiments and analysis, it was found that GFRP laminates will exhibit obvious aging phenomena under the action of UV light, and their residual strength will gradually decrease. At the same time, by establishing a residual strength prediction model, the residual strength of GFRP laminates under different UV radiation conditions can be accurately predicted.精品文档---下载后可任意编辑Therefore, the results of this study have certain reference significance for engineers to select materials and design structures.Keywords: GFRP laminates; UV aging; residual strength prediction
