Abstract

This study examined the dynamic penetration phenomena of high-velocity impact of magnesium alloy CFRP (Carbon Fiber Reinforced Plastic) composite. Test materials for investigation are magnesium alloy(AZ31B), the heat-treated magnesium alloy (AZ31B-200°C, AZ31B-300°C, AZ31B-430°C), and carbon/epoxy laminated composite materials with fiber direction [0°]8, [0°/45°]4s, [ 0°/90°]4s, [ 0°/45°/90°]3s and [ 0°/45°/-45°/90°]2s. We used a ballistic range (one-stage light gas gun), and the test specimens were set at 0°obliquity at room temperature. A high-speed camera allowed us to capture and analyzed the dynamic penetration phenomena of the test specimen.
