What is Controllable energy-absorption behaviors of the perforated CFRP tube with an adhesively bonded CFRP patch about?
A controllable crushing failure mode is very crucial for the energy-absorption (EA) of CFRP structures under the crushing load. However, the structural instability caused by middle-height fracture always occurs in the perforated CFRP structures, leading to low energy-absorption capacity. In this study, a controllable energy-absorption behavior of the perforated CFRP tube was induced by an adhesively bonded CFRP patch. Through numerical investigations, it was found that this method is very effective in reducing the stress concentrations around the hole and then avoiding the middle-height fracture at the initial stage. Hence, effects of adhesive bonding strength, ply-number of patch and single- or double-sided patching on the EA of the perforated CFRP tube were studied for further understanding of patching enhancement mechanisms. It was concluded that the EA of tube increases with the increase of adhesive bonding strength and ply-number of the patch, but the increment by increasing the ply-number of the patch is limited to the adhesive bonding strength. The double-sided patching was proved to be more effective in improving EA and specific energy-absorption than any single-sided patch
