Study of the Ballistic Impact Behavior of Protective Multi-Layer Composite Armor

The abalone shell, a composite material whose cross-section is composed of inorganic and organic layers, has high strength and toughness.Inspired by the abalone shell, several multi-layer composite plates with different layer sequences and thicknesses are studied as bullet-proof material in this paper.To investigate the ballistic performance of this multi-layer structure, the complete characterization model and related material parameters of large deformation, failure and fracture of Al 2 O 3 ceramics and Carbon Fiber Reinforced Polymer (CFRP) are studied.
