The microscopic damage in filament-wound carbon fiber reinforced plastics (CFRP) laminated pipes with three different laminate thicknesses subjected to impact loading were investigated in the present study. The impact tests were conducted to investigate the effect of the laminate thickness on the damage progress using a drop-weight testing device. The impact loading caused fiber damages and delamination in the all types of composite pipes. Delamination was suppressed in the thicker specimen. As a result, the absorbed energy became smaller with increasing laminate thickness. Internal pressure test were also conducted on the specimens after impact tests. The residual strength was larger in the composite pipes with thicker CFRP layers. These results prove that the composite pipes with thicker CFRP layers are superior in the impact resistance.
