Abstract:
Soft body armor for ballistic performance against ballistic projectiles comprising a ballistic panel having an interleaved construction of a generally vertically oriented plurality of layers of non-quilted interleaved sheets of woven fiber cloth and sheets of cross plied unidirectional tape adjacently interleaved in an interleave ratio of plies of said sheets of cross plied unidirectional tape to plies of said woven fiber cloth within each layer of said plurality of layers, so as to form a multiplicity of impedance mismatched transition zones in an array between a front face of said ballistic panel and a back face of said ballistic panel, said plurality of layers forming a non-quilted array between said front face of said ballistic panel and said back face of said ballistic panel, wherein said interleave ratio of plies of said sheets of cross plied unidirectional tape to plies of woven fiber cloth within each layer of said plurality of layers is greater than or equal to 1:1 and less than or equal to 4:4, and wherein the total number of said plies of said sheets of cross plied unidirectional tape is equal to or greater than the total number of said plies of woven fiber cloth within said plurality of layers, and wherein said plurality of layers comprises at least six of said layers interleaved in said ballistic panel.
