Claims70
A flexible penetration resistant composite comprising
- a. at least one fibrous layer comprised of a network of fibers, a portion of said fibers having a tenacity equal to or greater than about 10 g/d, a tensile modulus equal to or greater than about 150 g/d and an energy-to-break equal to or greater than about 10 j/g;
- and
- b. at least one continuous polymeric layer comprised of a thermoplastic resin, a thermosetting resin or a combination thereof, said continuous polymeric layer coextensive with, in contact with and at least partially bound to a surface of one of said fibrous layers.
A flexible penetration resistant composite comprising
- a. at least one fibrous layer comprised of a network of fibers, a portion of said fibers having a tenacity equal to or greater than about 10 g/d, a tensile modulus equal to or greater than about 150 g/d and an energy to break equal to or greater than about 10 j/g, and
- b. a plurality of discontinuous polymeric layers, each of said discontinuous polymeric layers being comprised of a thermoplastic resin, a thermosetting resin or a combination thereof, each of said discontinuous polymeric layers being in contact with and at least partially bound to a surface of one of said fibrous layers, said discontinuous polymeric layers completely covering a surface area equivalent to the surface of one of said fibrous layers when superimposed.
