 Full text | Abstract: The impact response of a composite laminate structure was investigated by subjecting several stacking sequences of a composite laminate structure to low velocity impact loading using a Drop-Weight Machine (CEAST 9350 drop tower) and three-point bending using an electronic universal tester (Type: WDW-20) machine. The air-coupled ultrasonic C-scan technique (NAUT21) was selected in order to characterise the impact damage size, delamination, flaw detection, and damage in composite laminate structures. The failure processes of damaged specimens for impact energy (5 J) were evaluated by comparing load-displacement curves and images of damaged samples taken from impacted sides through a C-scan. |
