Protective multilayer armor construction

A protective armor construction having a front and back and comprising multiple layers arranged in serial relation between the front and back of the armor construction, said multiple layers including:

• a plurality of layers of a penetration resistant material fabricated of high strength aramid fibers, said layers having peripheral edges and being secured together at said peripheral edges to form a first sub-unit;
• and at least one further sub-unit comprising at least one further layer of a penetration resistant material fabricated of high strength aramid fibers, said at least one further layer being disposed in unsecured relation to said first sub-unit and including a front facing side unsecured to any of said multiple layers, said further sub-unit further comprising a plurality of polyester layers comprised of a thermoplastic polyester comprising a long chain synthetic polymer of dihydric alcohol and dibasic acids or esters thereof, said polyester layers including an adhesive coating on one side thereof and said one side of each of said polyester layers facing toward the front of the armor construction, the adhesive coating on said one side of a frontmost polyester layer of said plurality of thermoplastic polyester layers being secured to a back facing side of said further layer of penetration resistant material and the adhesive coating of each of said polyester layers other than said frontmost layer being secured to back facing side of an adjacent polyester layer of said polyester plurality of layers so as to form said further sub-unit.
