Abstract
Ceramic tiles are often preferred to prevent projectiles from penetrating lightweight armour systems. This study investigates the effect of projectile impact on the glass fibre-reinforced composite (GFRP) with ceramic sheet sandwich panels. In the experiments, using a single-stage gas gun, 15 mm hemispherical and conical projectiles were impacted on 140 × 140 mm sandwich plates at velocities of about 80 m/s. Four shots for each hemispherical and conical projectile were fired on, 4-layer GFRP layer, 2-layers of GFRP with ceramic core and 4-layers of GFRP with ceramic sheet totalling 32 samples. Perforated panels were investigated for damage using C-scan. The effect of adding the ceramic sheet was evident in the energy absorption of the laminate. In comparison between glass fibre laminate and glass fibre/ceramic sandwich panels, it was observed that the ballistic limit was enhanced by 10% with the addition of a ceramic sheet in the laminate. Further, it also shows that adding GFRP can improve the ballistic resistance of the proposed GFRP/ceramic composite sandwich.
