摘　　要：碳纤维增强复合材料因其良好的力学、物理和化学性能,在多个工业领域获得了广泛应用。在工程应用中,关键结构的服役寿命和性能耐久性是一个不可忽视的问题。碳纤维增强复合材料通常以树脂为基体,而树脂易受环境影响发生老化,对复合材料的性能产生显著影响。本文首先介绍了环境温度对碳纤维增强复合材料性能的影响,并总结了水分扩散理论及常见的复合材料吸湿模型,然后整理了湿热耦合环境对碳纤维增强复合材料性能的影响效应,包括理论分析、试验方法以及有限元仿真等研究手段,最后讨论了碳纤维增强复合材料在湿热老化研究方面存在的问题和挑战,并对可行的研究方向进行了展望。Carbon Fiber Reinforced Polymers(CFRP)have been widely used in many industrial fields due to its satisfactory mechanical,physical and chemical properties.In engineering application,the service life and performance durability are key issues.Resin is usually adopted as the matrix of CFRP,which is easily affected by the environment,leading to significant impact on the composite performance.First,this paper introduces the effects of environmental temperature on the properties of CFRP,summarizing the theory of moisture diffusion models.Then,this paper sorts out the effects of moisture-temperature coupled environment on the properties of CFRP,including theoretical,experimental and finite element methods,etc.Finally,combined with the problems and challenges on the research of hygrothermal aging in CFRP,feasible research directions are prospected.
