摘要
通过实验研究了复合材料圆管端部加缠碳纤维对其轴压性能的影响,并对轴压破坏模式进行了分析。结果表明,复合材料圆管端部加强后,其轴压破坏模式和破坏位置都发生了改变。在轴压载荷作用下,端部加强能减小管的径向变形,并能更好地传递载荷,对提高复合材料圆管的压缩性能有利。
The effects of end-strengthening with carbon fiber on the axial compressive properties of the composite tubes were investigated by experiment, and the axial compressive failure modes were analyzed. The experimental results show that both the failure modes and crack position of the tubes under axial compressive load changed when the end of the composite tubes are strengthened. End- strengthening evidently reduces the radial deformation and translates the compressive loads much better; therefore end-strengthening can improve the axial compressive properties of the composite tubes.
