Abstract
A ballistic resistant armor plate. The plate is a stack of laminae impregnated with an elastomer. Each lamina is a fabric of polyaramis impregnated with the elastomer. To prepare the armor plate, the stack of pre-impregnated laminae is cured, typically using heat and pressure. Typically, the elastomer does not react chemically with the but rather serves as a filler and binder.
Claims7
A ballistic resistant armour comprising a laminated plate, wherein a stack of laminae is bound by an elastomer and wherein each lamina comprises:
- a polyaramid fabric;
- an elastomer impregnated in said fabric, and
- wherein said elastomer forms a continuum throughout said stack of laminae.
A method for producing ballistic resistant armour using polyaramid fabric plates, comprising the steps of:
- preparing prepregs by impregnating a plurality of said fabric plates with a liquefied form of an elastomer monomer;
- drying said prepregs
- trimming said prepregs;
- forming a stack of said prepregs, and
- curing said stack;
A method for controlling the delamination tendency of a laminated armour plate impregnated with an elastomer, by changing the amount of elastomer impregnated in said laminated armour plate.
A method for fixing ceramic tiles to a laminated ballistic armour plate, wherein said tiles are embedded in a face of a continuum of an elastomer spanning said armour plate.
