Piercing and trimming are essential because composite structures are usually manufactured in a near-net shape to reduce machining operations. Punching and shear cutting using out-of-plane shear loading are expected to increase productivity. Nevertheless, little is known about the effects of such operations on polymer-matrix composites. This study presents on the characterization of anisotropic piercing damage in typical carbon fiber reinforced plastic (CFRP) cross-ply laminates [0°2/90°2]s after punching using drop-weight impact (DWI) loading. During DWI punching, amount of piercing damage can be reduced, and the difference in amount of damage due to anisotropy associated with edged punching was smaller.
