Abstract
A hard armor composite includes a rigid facing and a ballistic fabric backing. The fabric backing is carried by the facing, and includes an array of bundled high-performance fibers. The fibers have a tensile strength greater than 7 grams per denier and a denier per filament ratio of less than 5.4.
Claims18
A hard armor composite, comprising:
- (a) a rigid facing;
- (b) a lightweight ballistic fabric backing carried by said facing, and comprising an array of bundled high-performance fibers, said fibers having a tensile strength greater than 7 grams per denier and a denier per filament ratio of less than 5.4, and said fabric backing comprising a plurality of overlying fabric layers, and said fabric backing and said rigid facing having a combined thickness of less than 0.900-inches, and wherein a thickness of said fabric backing comprises greater than 60% of the combined thickness of said fabric backing and said rigid facing;
- (c) said hard armor composite having an areal density not greater than 5.1 psf;
- and
- (d) means for adhering said fabric backing to said facing, said means for adhering being selected from a group consisting of a polymer film, an epoxy adhesive, a polysulfide adhesive, a polyurethane adhesive, a phenolic adhesive, a polyester adhesive, a polyvinyl butyral adhesive, a polyolefin adhesive, and a vinyl ester adhesive.
