复合腔体轴心抗压性能试验研究

Experimental Study of the Compressive Property of Compound Cavity Axis

摘要: 本文研究了两组复合腔体试件在轴心压力作用下的性能。利用万能试验机对该复合材料进行轴心压缩试验。研究发现：在试验过程中，两组复合腔体试件的破坏过程相似，均为外裹碳纤维首先出现拉断剥离现象，其后钢管屈服。但是由于加工工艺不同导致两组试验结果的屈服荷载以及破坏荷载不同。

Abstract: Two sets of experiments were carried out on CFRP and steel members under axial compression. The results indicated that the two sets of specimens experienced similar structural behavior under compressive loads. The CFRP spalling appeared before the yielding of steel tubes. However, due to the difference between the configuration and material of two sets of specimens, their yielded strength and ultimate load-bearing capacity differed to some extent.
