Improved armor structure comprised of an assembly of stacked, plastic plates of a first density and a layer of plastic material of a second density different from the first density between each pair of adjacent plates, respectively. Each plate is comprised of a number of layers of reinforcing material, such as fiber glass material, embedded in a resin to form a monolithic construction. Each layer is comprised of a mat of suitable material, such as fiber glass, impregnated with a binder, such as polyester resin. The layer has a finite thickness generally less than the thickness of each plate. The outer plates of the stack have exposed outer surfaces free of additional structure. The difference in densities of the plates and the layers causes delamination at one or more of the interfaces therebetween when the shock wave of a projectile entering the assembly partially propagates through and is partially reflected by such interfaces so as to dissipate the energy of the projectile itself.
