纤维增强聚合物（FRP）复合材料是民用基础设施中最适用的材料之一，因为它已被证明在高强度和刚度重量比以及抗腐蚀方面具有优势。玻璃钢在高温下的性能受到学术界和工业界的广泛关注。本文综述了FRP复合材料在高温（从环境温度到火灾）作用下力学性能的实验和数值研究。综述了100多篇关于FRP材料力学性能的研究论文，包括抗拉、抗压、抗弯、抗剪强度和模量。虽然他们报告的数据分散，但从这些研究中可以得出一些有趣的结论。通常，暴露于接近和高于树脂玻璃化转变温度Tg的高温对FRP材料的机械特性具有不利影响。另一方面，低于Tg的升高的温度可导致低水平的降解。讨论了不同FRP构件的退化机理。该审查概述了对今后工作的建议。FRP复合材料在高温下的行为提供了一个全面的了解基于数据库。此外，使用本综述提出的研究结果，可以为确定暴露于高温下的FRP材料的预测模型奠定基础。
Fibre-reinforced polymer (FRP) composite is one of the most applicable materials used in civil infrastructures, as it has been proven advantageous in terms of high strength and stiffness to weight ratio and anti-corrosion. The performance of FRP under elevated temperatures has gained significant attention among academia and industry. A comprehensive review on experimental and numerical studies investigating the mechanical performance of FRP composites subjected to elevated temperatures, ranging from ambient to fire condition, is presented in this paper. Over 100 research papers on the mechanical properties of FRP materials including tensile, compressive, flexural and shear strengths and moduli are reviewed. Although they report dispersed data, several interesting conclusions can be drawn from these studies. In general, exposure to elevated temperatures near and above the resin glass transition temperature, Tg, has detrimental effects on the mechanical characteristics of FRP materials. On the other hand, elevated temperatures below Tg can cause low levels of degradation. Discussions are made on degradation mechanisms of different FRP members. This review outlines recommendations for future works. The behaviour of FRP composites under elevated temperatures provides a comprehensive understanding based on the database presented. In addition, a foundation for determining predictive models for FRP materials exposed to elevated temperatures could be laid using the finding that this review presents.
