Abstract

A ballistic resistant article includes a front strike face and a backing that is bound by stitching to the front strike face. The front strike face includes a rigid layer and the backing includes at least one non-rigid fibrous layer. The front strike face and the flexible backing have a combined weight, and the rigid front strike face can be 1% to 20% of the combined weight.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A ballistic resistant article comprising a front strike face and a backing that is bound by stitching to the front strike face, the front strike face including a rigid layer and the backing including at least one non-rigid fibrous layer. 
     
     
         2 . The ballistic resistant article as recited in  claim 1 , wherein the front strike face includes a layer of fibers disposed in a polymer matrix. 
     
     
         3 . The ballistic resistant article as recited in  claim 1 , wherein the front strike face is non-fibrous. 
     
     
         4 . The ballistic resistant article as recited in  claim 1 , wherein the front strike face includes aramid fibers. 
     
     
         5 . The ballistic resistant article as recited in  claim 1 , wherein the at least one non-rigid fibrous layer includes aramid fibers. 
     
     
         6 . The ballistic resistant article as recited in  claim 1 , wherein the at least one non-rigid fibrous layer includes unidirectional fibers. 
     
     
         7 . The ballistic resistant article as recited in  claim 1 , wherein the at least one non-rigid layer includes a woven fabric. 
     
     
         8 . The ballistic resistant article as recited in  claim 1 , wherein the front strike face and the backing have a combined weight, and the front strike face is 1% to 20% of the combined weight. 
     
     
         9 . The ballistic resistant article as recited in  claim 1 , wherein the rigid layer has at least two times the rigidity of the at least one non-rigid fibrous layer. 
     
     
         10 . The ballistic resistant article as recited in  claim 1 , wherein the at least one non-rigid fibrous layer includes a plurality of fibrous layers, and the fibrous layers are bound to each other and to the rigid layer exclusively by the stitching. 
     
     
         11 . A ballistic resistant article comprising a rigid front strike face and a flexible backing that is loosely bound to the rigid front strike face, the rigid front strike face including a layer of fibers disposed in a polymer matrix and the flexible backing including a plurality of fabric layers, the rigid front strike face and the flexible backing having a combined weight, and the rigid front strike face is 1% to 20% of the combined weight. 
     
     
         12 . The ballistic resistant article as recited in  claim 11 , wherein the rigid front strike face is 1% to 10% of the combined weight. 
     
     
         13 . The ballistic resistant article as recited in  claim 11 , wherein the rigid front strike face is 5% to 10% of the combined weight. 
     
     
         14 . The ballistic resistant article as recited in  claim 13 , wherein the layer of fibers is of aramid fibers. 
     
     
         15 . The ballistic resistant article as recited in  claim 14 , wherein the fabric layers are of aramid fibers. 
     
     
         16 . The ballistic resistant article as recited in  claim 15 , wherein the flexible backing is loosely bound by stitching to the rigid front strike face. 
     
     
         17 . The ballistic resistant article as recited in  claim 16 , wherein the fabric layers are free of any matrix material. 
     
     
         18 . A ballistic resistant article comprising a rigid front strike face and a flexible backing that is bound by stitching to the rigid front strike face, the rigid front strike face consisting of a layer of fibers disposed in a polymer matrix and the flexible backing consisting of a plurality of fabric layers, the fabric layers are bound to each other and to the rigid front strike face substantially exclusively by the stitching, the rigid front strike face and the flexible backing having a combined weight, and 1% to 10% of the combined weight is the rigid front strike face. 
     
     
         19 . The ballistic resistant article as recited in  claim 18 , wherein the layer of fibers and the fabric layers are each of aramid fibers, and the fabric layers are free of any matrix material.
