影响FRP基本力学性能的因素

Factors to influence fundamental mechanical behaviors of FRP

近年来,FRP以其高强、轻质、耐腐蚀、抗疲劳、施工便捷等优点,作为土木工程的一种新型结构材料,在对已有结构物的加固方面,得到广泛应用。但是FRP浸胶固化后影响其力学性能指标的影响因素很多,因此,本文以实验室条件下测定材料性能的标准为基础,系统地测定了CFRP、GFRP、AFRP及HFRP拉伸试验时的力学性能指标,希望通过对其力学指标相关影响因素的分析,加深对FRP复合材料的力学性能的认识,对实际加固工程的设计、施工有所启示。

<Abstrcat>Recently, FRP (Fiber Reinforced Polymer) has been widely used for strengthening existed structures as a new kind of material with many advantages, such as high strength, light mass, anti-corrosion and construction easily. However, there are many factors influencing the mechanical behaviors of material after fiber sheets are mixed with binder and coagulated. Therefore, on the basis of the standards for testing material in lab, tensile mechanical properties were systematically tested for CFRP, GFRP, AFRP and HFRP. It is expected that the mechanical properties of FRP compound material can be known well,which may be helpful for practice and construction.
