Abstract Two different quasi-static crushing tests have been performed to investigate the effects of humid ageing on the crashworthiness behaviours of the Carbon Fiber Reinforced Polymer (CFRP) laminates. Four different types of specimens made from T700/M21 and Cytec woven CFRP materials were placed in a humidity-controlled chamber at 90% relative humidity (RH) and 80 °C until they reach saturation before performing the crushing tests. From the result obtained, the behaviour of the force–displacement curves, crushing morphologies and damage mechanisms between humid ageing specimens and the sane specimens are very similar. Nevertheless, in terms of ply mean crushing stress analysis it is quantitatively proven that there are drops nearly to 10% on the CFRP laminates have been exposed to the humidity environment. This result has been verified numerically via an existing Abaqus/Explicit model which demonstrates a good agreement with the experimental results.

湿老化对 CFRP 层压板耐撞性能影响的实验和数值研究

摘要 为了研究湿老化对碳纤维增强聚合物 (CFRP) 层压板耐撞性能的影响，进行了两种不同的准静态压碎试验。由 T700/M21 和 Cytec 编织 CFRP 材料制成的四种不同类型的试样被放置在 90% 相对湿度 (RH) 和 80°C 的湿度控制室中，直到它们在进行压碎测试之前达到饱和。从获得的结果来看，潮湿老化试样和正常试样之间的力-位移曲线的行为、压碎形态和损伤机制非常相似。然而，就层平均压碎应力分析而言，定量证明暴露在潮湿环境中的 CFRP 层压板有近 10% 的下降。
