摘　　要：纤维增强复合材料(FRP)对于木材力学性能改善及木结构加固、修复的优良性能使其成为新型复合材料研究的热点。FRP-木材黏结加固受FRP材料、木材基体与胶黏剂等多重因素协同作用影响,其界面的黏结状况问题尤为关键,决定着复合材料结构的性能和寿命。因此,结合木材生物性属性和木结构独特结构特性,从材性变化、预处理、FRP形制、胶黏剂特性、外部环境五方面系统梳理、总结了国内外FRP-木材界面黏结性能的最新研究成果,旨在厘清FRP-木材界面黏结性能的耦合影响因素。同时分析了现有FRP-木材黏结加固研究存在的不足,并对未来研究工作的新趋势、新发展与新方向进行了展望,为今后拓展FRP高质、高效的应用特别是古建筑木结构的保护提供重要参考。Due to the excellent mechanical properties of fiber-reinforced polymers(FRP)for improving the mechanical properties of wood and strengthening and repairing timber structures,it has become the focus of research on new composite materials.FRP-wood bonding reinforcement is affected by the synergistic effect of multiple factors such as FRP materials,wood matrices and adhesives,and the bonding state of its interface is particularly momentous,which determines the performance and life of the composite structure.Therefore,combined the biological properties of wood and the unique structural characteristics of wood structure,the five aspects were systematically combed,that was material changes,pretreatment,FRP formation,adhesive properties,and environmental condition.And the latest domestic and foreign research results of FRP-wood interface bonding properties were summarized to clarify the coupling factors that affect the bonding performance of FRP-wood interfaces.In addition,the deficiencies in research were analyzed of existing FRP-wood bonding and reinforcement,and the new trends,new developments and new directions for future research were imagined,which might provide important reference to the future expansion of FRP high-quality and high-efficiency application,especially the protection of ancient architectural wood structures.
