摘要
GFRP(玻璃纤维增强塑料)具有高强、质轻、抗疲劳、耐腐蚀等优良特性,逐步用作各种结构材料。针对GFRP材料的力学特性研究已较为完善。考虑到型材和材料的特性不尽相同,对于其型材的力学性能研究还在探索中。试验表明破坏形态和强度值与试件构造存在密切联系,综合分析给出了该型材的合理的抗压强度参考值,供今后使用设计参考。
Having the excellent characteristics of being high in strength, light in weight, and good in fatigue-resistance and cor- rosion-resistance,GFRP （Glass Fiber Reinforced Polymer）is gradually used as structural materials for many different kinds of structures. The study of the mechanical properties of GFRP is already quite perfect. With differences among the properties of different figured members and materials taken into account, the mechanical properties of the figured members of GFRP still need exploring. Our experiments show that the failure modes and values of strength of the specimen made are closely related to the structural forms of them. The comprehensive analysis of them provides us with a reasonable reference value of the compres- sive strength of the figured member. It may serve as a useful reference for the design and use of them in the future. Key words：
