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.

Badano odpowiedź na udar struktury laminatów kompozytowych. Zastosowano kilka sekwencji udarów charakteryzujących się małą prędkością. Stosowano specjalną maszynę umożliwiającą opadanie obciążenia (wieża udarowa). Zginanie następowało w systemie trzech punktów podparcia. Zastosowano sprzężoną technikę ultradzwiękowego skanowania dla scharakteryzowania wielkości uszkodzeń w wyniku udaru, delaminację warstw i zmiany strukturalne. Dla scharakteryzowania uszkodzeń materiału badawczego powstałych przy energii udaru 5J wykorzystano porównanie wykresów obciążenie-przesunięcie i zdjęć uszkodzonych próbek.
