Explosive Blast Response of Naval Composites in Arctic Conditions
Abstract
United States Navy ships are operating in the Arctic region where the air temperature can dropto about 50C during winter. The mechaUnited States Navy ships are operating in the Arctic region where the air temperature can dropto about 50oC during winter. The mechanical properties of the composites materials used onnaval ships are sensitive to temperature, and some properties may be reducednical properties of the composites materials used on naval ships are sensitive to temperature, and some properties may be reduced in freezing Arctic conditions. It is feasible that the deformation and damage resistance of composite materials impulsively loaded by in freezing Arcticconditions. It is feasible that the deformation and damage resistance of composite materialsimpulsively loaded an explosive blast may be adversely affected by cold temperatures,thereby reducing the blast resistance of naval composites ship s by an explosive blast may be adversely affected by cold temperatures,thereby reducing the blast resistance of naval composites ship structures operating in Arcticwaters. However, little is known about the effect of cold temperatures on the explosive blastrespotructures operating in Arctic waters. However, little is known about the effect of cold temperatures on the explosive blast response of naval composite materials.The aim of this NICOP project is to investigate the influence of Arctic weather conditions on the expnse of naval composite materials.The aim of this NICOP project is to investigate the influence of Arctic weather conditions onthe explosive blast response of fiber-reinforced polymer laminates and sandwich compositesused in naval ships. In this project, blastlosive blast response of fiber-reinforced polymer laminates and sandwich composites used in naval ships. In this project, blast resp response is defined as the dynamic deformation,damage resistance and residual mechanical properties of a laminate or sandwich componse is defined as the dynamic deformation, damage resistance and residual mechanical properties of a laminate or sandwich composite material caused by an explosion. The materials studied in the project will include glass and carbon fiber reinforced laminates whicositematerial caused by an explosion. The materials studied in the project will include glass andcarbon fiber reinforced laminates which are used in naval ship topside structures and, in somecases, the hull. Sandwich composites with polymer foam core or balsa wh are used in naval ship topside structures and, in some cases, the hull. Sandwich composites with polymer foam core or balsa wood.ood
