To evaluate the damage of composite laminate structures which are consist of maraging steel, rubber and carbon fiber reinforced composite subjected to low velocity impact, the drop weight was used to impact the specimens and nondestructive evaluation using the C-scan was performed. After experiments, impact damages were compared with respect to various temperatures and impact energies. In case of circular plate, the damage characteristics such as delamination, matrix cracking, and fiber breakage were observed at the interface of rubber and carbon fiber reinforced composite. These results were found to be correlated with the deflection of specimen.
