Resistance of hybrid layered composite panels composed of fiber-reinforced cementitious composites against high-velocity projectile impact

Abstract The purpose of this study is to present an experimental investigation of the impact resistance of hybrid layered panels composed of high-strength fiber-reinforced composite and high-ductility fiber-reinforced composite. Seven types of panels were prepared with three types of composites and hybrid use of composites. A series of experiments including static loading tests and high-velocity projectile impact load tests was performed. From the test results, it was found that the hybrid layered panels, in which a high-strength composite was located at the front side and a high-ductility composite was located at the rear side, had impact resistance higher than those of other panels. It was also observed that the hybrid layered panels showed different damage patterns than those of the panels made of single material.
