Exposure to seawater and cold temperatures are known to degrade the mechanical properties of several materials, thus, compromising the safety of personnel and structures. This study aims to investigate the low-velocity impact behavior of woven carbon/vinyl ester sandwich composites with PVC foam core at low temperatures for marine applications. The tests were performed in a drop tower impact system with an in-built environmental chamber.
