ABSTRACT:
A ballistic resistant armor panel and a method of constructing the same utilizes a first layer of resin-impregnated fabric, a second layer of flexible woven fabric, a border layer of resin-impregnated fabric bordering the second layer, and a third layer of resin-impregnated fabric. The percentage by weight of resin in the first layer is such that the first layer distributes the impact of a projectile which strikes its surface over a large area of the panel and effectively contributes to the ability of the panel to stop and/or slow the projectile. Furthermore, the second layer of flexible woven fabric is encapsulated by the first, border and third layers. Such a construction minimizes blunt trauma in body armor in which the panel is utilized and preserves the dry ballistic resistance of the woven fabric comprising the second layer. The panel of the invention is particularly well-suited for utilization in a helmet, and a helmet which includes such a panel possesses very good ballistic resistance.
