摘要
纤维增强聚合物(FRP)复合材料具有轻质高强、耐腐蚀、经济效益高的优势,在基础建设施设中表现出巨大潜力,但在复杂环境下长期服役后,FRP复合材料的力学性能下降超过50%,限制了其在工程中的应用。基于此,针对FRP复合材料各组分优化设计方法进行了总结,并分析了热氧、紫外线、腐蚀介质环境中FRP复合材料的长期性能演化规律;根据化学结构及微观形貌分析,阐述了FRP复合材料在复杂环境中的劣化机制,进一步归纳了其在复杂环境下的长期性能预测模型,可为保证FRP复合材料在复杂环境中的长期使用性能提供理论依据,促进其在实际工程中的应用。
Fiber reinforced polymer(FRP) composite has great potential in infrastructure construction due to the advantages of light weight and high strength,corrosion resistance and high economic benefit.However,the performance of FRP composite will decrease by more than 50% after long-term service in complex environment,which limits its application in engineering.In the paper,the enhancement methods of different FRP composites components are reviewed.The evolution law of FRP composites on long-term properties under thermal oxygen,ultraviolet and corrosive media environment are revealed,and the deterioration mechanism of FRP composites in complex environment is elucidated by the analysis of chemical structure and microstructure.In addition,the long-term performance prediction model of FRP composites under complex environments is summarized,which can provide theoretical basis for ensuring the long-term performance of FRP composites in complex environment and promote its application in practical engineering.
