Composite materials and structures made of ultra-high molecular weight polyethylene (UHMwPE) are widely used in ballistic impact applications due to their high specific strength and stiffness. However, real world structures could have a curvature and it is important to understand their mechanical behaviour. Although the impact response of flat laminates has been extensively investigated and results available in the open literature, very little investigation has been carried out on the impact response of curved shells. In this study we experimentally investigate the impact response of curved Dyneema®HB26 laminates. Laminates with a thickness of 5 mm were impacted at velocities between 200 m/s and 700 m/s by 10 mm hardened steel balls fired using a single stage gas gun. The effect of the radius of curvature (5 in, 10 in and 20 in) and curvature type (concave and convex) were investigated. Measurements of the back-face deformation were made using the high-speed 3D digital image technique whilst post-impact damage was evaluated by observations of their sections. Experimental results revealed a dependency of the ballistic performance of the laminates with respect to the radius of curvature and curvature type. The ballistic limit determined for shells was higher compared to the V50 of flat laminates, regardless of the radius of curvature. Nevertheless, the back-face deformation was curvature dependant and higher compared to the back-face deformation measured on flat laminates.
