Abstract : This report presents the procedures developed for adopting a two-dimensional (2-D) analytical model of ballistic penetration and perforation in isotropic targets to target plates of composite materials (e.g., glass FIBER reinforced plastics GRP). The depths of penetration in S-2 glass fiber/polyester matrix composite laminates were calculated using this analytical model and compared with the measured data. The initial formulation is based on blunt-nosed rigid projectiles and normal impact velocities up to about 1 km/s. Some preliminary results are described, and directions for further investigations are indicated. This report also briefly reviews penetration mechanisms in GRP laminates and some experiments and analytical/computational modeling efforts by other investigators.
