Abstract

This study presents a combined experimental and theoretical analysis of both unidirectional and woven fabric composite sandwich beams under low velocity impact loading. The sandwich beams were fabricated by bonding carbon/epoxy facesheets to a balsa wood core. All constituent materials including facesheets, cores and adhesives were folly characterized separately under stress conditions similar to those encountered in the sandwich structures. A comprehensive study that includes fabrication, mechanical testing and analysis of these structures under both quasi-static and impact loading was performed. The failure mechanisms were also analyzed. Existing models developed by the authors for sandwich beams with PVC foam cores were extended to predict impact loads for sandwich beams with balsa wood core.
