玻璃钢管弯曲失效机理分析

Analysis of Bending Failure Mechanism of FRP Pipes

本文通过对弯曲破坏后的玻璃钢管试样断回微观形貌观察，分析了其可能的失效原因及失效机理，建议在进行玻璃钢管设计及制造时，应严格控制其纤维排列的均匀性。

This paper analyses the possible failure cause and mechanism of FRP pipes after the observation of microscopic rupture morphology of FRP pipe samples from the failed pipes due to bending, it also recommends fiber alignment should be strictly controlled during design and manufacture of FRP pipes
