Abstract
The effects of impact velocity and specimen thickness on the size distributions of ejecta resulting from projectile perforation of CFRP (carbon fiber reinforced plastic) plates were investigated. Two types of quasi-isotropic CFRP plates [+45° /0° /-45° /90° ]_<2s> (16 ply) and [+45° /0° /-45° /90° ]_<3s> (24 ply) were used for targets. Spherical projectiles made of aluminum alloy with a diameter of 7 mm (A2017-T4) were used. Projectiles were accelerated using a two-stage, light-gas gun at Nagoya Institute of Technology. The ejecta that were collected from in front of and behind the targets were compared.
