Dynamic Deformation of a Ceramic/GRP Composite From KE Impact
Abstract
Ceramic/GRP (Glass Reinforced Plastic) composite targets were inspected by hemispheric 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 Coors Ceramic of Golden, Colorado, USA. The 152-mm-x 152-mm- and 40-mm-thick ceramic tiles were confined in a steel frame and glued to the 40-mm-thick GRP panels. The GRP panels were in two sizes: 300 mm x 300 mm or 600 mm x 600 mm square. The dynamic bulging of the GRP panels during penetration was observed by means of two Cranz-Schardin high-speed cameras in side view and top view simultaneously. Distance-time curves of the bulging of the GRP panels are derived from the camera recordings for both panel sizes, and the damage of the targets is described.
