Abstract : Ceramic/GRP composite targets were impacted by hemispherically nosed tungsten 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 ballistic 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 (Glass Reinforced Plastic) laminates were S-2 Glass/Polyester fabricated by Simula Incorporated 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 Al203 ceramics which is nominally 99.5 % pure, produced by Coors Ceramic of Golden, Colorado, USA, under the tradename "CAP-3". The tiles of the dimensions 152 mm x 152 mm and 40 mm thickness were confined in a steel frame and glued to the GRP panels of 40 mm thickness and sizes of either 12" x 12" or 24" x 24" square. (MM)
