玄武岩纤维复合材料性能提升及其新型结构

ADVANCEMENT OF BASALT FIBER-REINFORCED POLYMERS (BFRPS) AND THE NOVEL STRUCTURES REINFORCED WITH BFRPS

  • 摘要: 纤维增强复合材料(FRP)具有轻质、高强、耐腐蚀、耐疲劳的优点,是结构加固增强的理想材料。其中,具有环境友好特性的玄武岩纤维复合材料(BFRP)有望推动工程结构的绿色可持续化发展,得到国家和地方政府的大力支持。为进一步提升BFRP增强工程结构的性能与寿命,还需从BFRP材料性能和结构增强形式等方面进行改善。该文阐述了BFRP高性能化技术,并从设计理念、关键技术和力学性能三个方面,对三种新型BFRP增强结构形式进行了综述,包括高耐久损伤可控BFRP筋/网格-钢筋混合配置混凝土结构、BFRP型材-混凝土组合结构以及BFRP拉索大跨结构,并对BFRP新建结构的发展提出了建议和展望。

     

    Abstract: The characteristics of light weight, high strength, corrosion- and fatigue-resistance make fiber-reinforced polymers (FRPs) serve as a type of ideal material for structural strengthening and reinforcement. Environmentally friendly basalt FRPs (BFRPs) are considered as a feasible type of material stimulating the development of sustainability of infrastructures and are supported by the national and local governments in their strategies. Further improvements in terms of the performances of BFRPs and types of structures reinforced with BFRPs are necessary for the enhancement of the performance and the service life of infrastructures reinforced with BFRP. The advancement technologies of BFRP are elaborated. Furthermore, three novel structures reinforced with BFRPs including concrete structures reinforced with BFRP bars/grids of high durability and damage controllability, BFRP-shell-concrete composite structure, and long-span structure with BFRP cable, are reviewed in terms of design philosophies, key technologies, and mechanical behaviors. Finally, several strategic recommendations are proposed for the prospects of newly-built structures reinforced with BFRP.
