摘要

摘要: 采用纤维缠绕成型工艺，设计两种尺寸的CFRP圆管，铺层方式均为[(90/0)2]S，对CFRP圆管进行压缩和拉伸试验，着重研究CFRP圆管在这两种受力状态下直至破坏的应力-应变关系，极限强度以及材料宏观破坏模式。试验结果表明：铺层方式为[(90/0)2]S的CFRP圆管抗拉极限强度和应变远大于其抗压极限强度和应变，但这两种状态下CFRP圆管的弹性模量大致相当，且破坏模式均为脆性破坏。

Abstract: The paper presents the results of an experimental and numerical investigation into the behaviour of carbon-fiber-reinforced epoxy tubes subjected to monotonic uniaxial loading.These tubes were winded by carbon fibers with a filament winding pattern of [(90/0)_2]_S.Two sizes of tubes were tested in a testing machine to investigate basic properties under uniaxial compression and tension loading.The resulting stress and strain curves were analyzed and the damage and failure modes were observed.It is shown that the ultimate stress and strain under tension are much larger than those under compression,however,the elastic module under these two states are similar if the CFRP tubes are winded with a filament winding pattern of 90/0.
