The use of viscoelastic materials, like cork, in sandwich composite structures significantly reduces weight and enhances impact and acoustic performance. This study investigated the low-velocity impact behaviour of rubberized cork sandwich structures with glass face sheets. The samples were tested using a drop-weight impact machine to evaluate the effect of impact energy on contact force, displacement, and absorbed energy. The results showed that impacted samples experience various types of fracture and fiber breakage. The findings suggest that glass/cork sandwich structures demonstrate adequate resistance and energy absorption capacity under increased impact energy. This study provides valuable experimental insights into the mechanical behavior of these structures under low-velocity impact, which could contribute to the improved design of impact-resistant sandwich structures.
