The Experimental Investigation of Low-Velocity Impact on Sandwich Structures with a Cork Core and Basalt Face Sheets

There is growing interest in the utilization and development of materials derived from renewable sources for various structural applications. Among these, cork-based structures have attracted considerable attention due to their potential for industrial use, particularly in safety equipment, protective devices, and other applications that demand efficient energy absorption. The results indicated that as impact energy increases, both the contact force and displacement of the samples rise significantly. The findings indicate that basalt/cork sandwich structures offer superior impact energy absorption capabilities and exhibit varying responses based on the impact conditions. This research can contribute to the improvement of design and enhancement of the safety of structures based on cork core and basalt fiber in various industrial applications.
