摘　　要：首先,本文采用各向异性弹性力学的方法,结合复合材料层合理论,研究了纤维缠绕层合圆管的应力分析和变形分析方法;其次,分析了由碳纤维复合材料(CFRP)构成的圆管的强度;而后,对纤维缠绕成型的两种尺寸的CFRP圆管进行压缩和拉伸实验,着重研究了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。Firstly,the stress and strain analysis method of filament winding foam-filled tube is investigated according to anisotropic elasticity theory and lamination theory of composite material.Secondly,the strength of carbon-fiber-reinforced epoxy tubes is obtained.Then,two types of CFRP tubes are designed by using the filament winding forming technology.The compression and tensile test are also carried out to investigate the stress-strain relationship,ultimate strength and macroscopic failure mode of the former CFRP tube.
