金属管外壁用碳纤维缠绕复合后,其承受横向与轴向压载荷的能力均茯得了明显的提高。尤其是细长管缠绕碳纤维后,对轴向压载荷的抗弯曲变形及抗压极限承载能力都有大幅度的提高。本文介绍了硬 Al 合金(LY-11Al 合金)圆管在外壁缠绕复合碳纤维前后承受压载能力的实验数据的对比,以及对未经缠绕复合的承压管的理论临界压力进行探讨,分析了缠绕碳纤维能提高承载能力的原因。 The outer wall of the metal pipe wrapped with carbon fiber composite, its ability to withstand horizontal and axial compressive load are significantly improved. In particular, slender tube wrapped carbon fiber, the axial compressive load bending deformation and ultimate compressive load capacity has greatly improved. In this paper, we compare the experimental data of the hard aluminum alloy (LY-11Al alloy) round tube before and after the composite carbon fiber is wound on the outer wall, and discuss the theoretical critical pressure of the non-wound composite pressure pipe. Carbon fiber can increase the carrying capacity of the reasons.
