ABSTRACT:
A laminar system for constructing doors and window shutters, to harden the nside of walls and to greatly increase the penetration resistance of structures. The sketch illustrates the material system and gives representative material thicknesses. The laminar system comprises an outer steel sheet, hardwood, polycarbonate plastic, a ballistic resistant (hardened steel) sheet, and an inner sheet of steel; the materials are laminated in the order given from the outside (attack side) to the inside. This laminar materials systems (used as a 3 foot wide by 7 foot high door, for example) provides greater penetration and ballistic resistance with lighter weight than prior systems.
