Abstract
A composite fabric, capable of stopping the penetration of a 44 Magnum, made up of layers of non-woven and woven fabrics of Kevlar, and/or Spectra, or the like high molecular weight polymer filaments, wherein the layers of woven fabric are quilted together in a spacing sufficient to absorb the lateral component of the bullet's impact energy at an areal density of less than 1.15 lbs. per square foot and a deformation of less than 44 mm.
Claims21
A pliable fabric, adapted to be disposed between an object in need of protection against impingement of an incoming projectile traveling toward said object and said incoming projectile comprising:
- a first side directed away from said object and toward said incoming travelling projectile, and
- a second side directed toward said object,
- wherein said first side of said fabric comprises a first element comprising an unquilted multiplicity of sub-layers of non-woven fabrics, the filaments of which comprise very high molecular weight polymer material;
- and
- wherein said second side of said fabric comprises a second element comprising a quilted together multiplicity of sub-layers of woven fabrics, the filaments of which comprise very high molecular weight polymer material.
A pliable garment having a first side and a second side, wherein said garment is adapted to be disposed in proximity to an object in need of protection against impingement of an incoming projectile traveling toward said object, and is adapted to be disposed between said incoming projectile and said object, which garment has at least one pocket disposed on said first side directed toward said incoming projectile, and wherein there is disposed in at least one of said pockets at least one discontinuous piece of a composite material comprising:
- a first element directed away from said garment and toward said incoming travelling projectile, and
- a second element directed toward said garment,
- wherein said first element of said composite material comprises a multiplicity of unquilted sub-layers of non-woven fabric the filaments of which comprise very high molecular weight polymer material;
- and
- wherein said second element of said composite material comprises a quilted together multiplicity of sub-layers of woven fabrics, the filaments of which comprise very high molecular weight polymer material.
A pliable garment comprising an inside surface and an outside surface, which garment is adapted to be disposed between an object in need of protection against impingement of an incoming projectile traveling toward said object and said incoming projectile, which garment comprises a pliable fabric comprising:
- a first side, corresponding to said outside surface, directed away from said object and toward said incoming travelling projectile, and
- a second side, corresponding to said inside surface, directed toward said object,
- wherein said first side of said fabric comprises a first element comprising an unquilted multiplicity of sub-layers of non-woven fabrics, the filaments of which comprise very high molecular weight polymer material;
- and
- wherein said second side of said fabric comprises a second element comprising a quilted together multiplicity of sub-layers of woven fabrics, the filaments of which comprise very high molecular weight polymer material.
