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。
CFRP pipe with two sizes was designed by fiber winding process. The way of laying was [(90 ° / 0 °) 2] S. The CFRP pipe was subjected to compression and tensile test. The CFRP pipe was emphatically studied The stress-strain relationship, the ultimate strength and the macroscopic failure mode of the material under two kinds of stress conditions. The experimental results show that the tensile ultimate strength and strain of the CFRP pipe with [(90 ° / 0 °) 2] S are much larger than the ultimate strength and strain of the CFRP pipe. However, the CFRP pipe’s elasticity The modulus is roughly equivalent, and the failure mode is brittle failure.
