Dynamic Deformation of a Ceramic/GRP Composite From KE Impact

摘要

Ceramic/GRP (Glass Reinforced Plastic) composite targets were inspected byhemispheric alloy projectiles (L= 55 mm, D = 17 mm, m = 214 g) at velocities of about 1000 m/s. The impact velocities were chosen close to the balisitic limit of this projectile-target combination, which was determined from parametric tests conducted by the U.S. Army Research Laboratory, Aberdeen Proving Ground, Maryland, USA. The GRP laminates were S-2 Glass/Polyester fabricated by Simula, Inc. of Phoenix, Arizona, USA. Simula also glued the ceramic tiles to the S-2 glass using standard assembly techniques to maintain a consistent bond-interface thickness. The ceramic used in these tests was sintered AD995 alumina produced by
