摘要

具有轻质、高强和耐腐蚀等优异特性的纤维增强树脂基复合材料(FRP)

已被广泛应用于航空航天工程、船舶与海洋工程、土木工程等领域。然而基体树脂固有的可燃性

使得FRP会在高温(火灾)环境下发生复杂物理、化学变化

造成力学性能下降

而强度和刚度的下降可能会导致结构变形和倒塌

甚至造成人员伤亡。因此

研究复合材料的高温力学性能对确保复合材料结构的消防安全至关重要。本文综述了国内外FRP高温力学性能的试验结果与理论预测模型:对比分析了既有试验测试方法异同;分析归纳了树脂类型、复合材料界面、增强纤维类型与铺层方式、防火涂层等对复合材料高温力学性能的影响;最后指出了未来需进一步研究的方向。

Abstract

Fiber reinforced polymer (FRP) has been widely used in marine engineering

aerospace engineering

civil engineering and other fields due to its lightweight

high strength and corrosion resistance. However

the inherent flammability of matrix resin makes FRP undergo complex physical and chemical changes in high temperature (fire) environment

resulting in a decrease in mechanical properties. The decrease in strength and stiffness may lead to structural deformation and collapse

resulting in property losses and even casualties. Therefore

it is very important to study the mechanical properties of composite at elevated temperatures to ensure the fire safety of composite structures. The experimental and theoretical research results of high-temperature mechanical properties of FRP at home and abroad were reviewed. Several models for predicting the loss in the mechanical properties are described. Firstly

The similarities and differences of the existing test methods were compared and analyzed. Secondly

the test results of high temperature mechanical properties of composite materials are briefly introduced. The effects of matrix resin type

composite interface

reinforced fiber type and coating method

and fireproof coating on high-temperature mechanical properties of composite were analyzed and summarized. Finally

the direction for further research in the future was prospected.
