BFRP-FRCM复合层研究进展

STATE-OF-THE-ART OF BFRP-FRCM COMPOSITE LAYER

玄武岩纤维网格-纤维增强水泥基基质复合层(BFRP-FRCM)作为一种新型加固材料,既能充分利用玄武岩纤维轻质高强和易于施工的特点,又能避免使用粘结剂在潮湿、高温、火灾等环境因素下导致的加固效果下降,是一种具有良好加固性能的材料,在混凝土结构和砖砌体结构加固方面得到了广泛应用。本文通过总结国内外对该复合层的材料性能、力学性能及耐久性的研究现状,分析将其应用于加固工程的利弊,为该项加固技术的优化与发展提供一定的参考。

Basalt fiber reinforced polymer-fabric reinforced cementitious matrix(BFRP-FRCM)composite layer,as a new type of reinforcement material,can apply the lightweight,high-strength and easy construction abilities of BFRP effectively.Meanwhile,when structures strengthened by BFRP-FRCM composite layer service incomplex environments of humidity,high temperature,fire,etc.,steady cohesive of BFRP-FRCM will not reduce the reinforcement effect.Therefore,BFRP-FRCM is a kind of effective reinforcement material and has been widely used in the reinforcement of concrete and masonry structures.This paper systematically summarized the research progress of the mechanical performance,reinforcement performance and durability of BFRP-FRCM composite layer.The advantages and disadvantages of BFRP-FRCM reinforced components were discussed to provide advices for the further studies,including the optimization and development of BFRP-FRCM reinforcement technology.
