Abstract:
1. A stab and ballistic resistant material, comprising a stab-resistant layer and a ballistic resistant layer, wherein the stab-resistant layer comprises at least one layer, wherein each layer of the at least one layer is constituted of two structural units, each of the two structural units is formed from perpendicularly combined high strength and high module unidirectional fiber prepreg strips, and the fibers of adjacent layers in adjacent structural units are arranged at an angle of no higher than 45°; a biaxially oriented organic membrane is adhered to both sides of the stab-resistant layer with a solvent adhesive selected from the group consisting of styrene-ethylene-ethylene-propylene-styrene polymer and maleic anhydride modified styrene-ethylene-butylene-styrene polymer; the ballistic resistant layer comprises at least one layer, wherein each layer of the at least one layer is constituted of two structural units, each of the two structural units is formed from perpendicularly combined high strength and high module unidirectional fiber prepreg strips, and the high strength and high module fibers of adjacent layers in adjacent structural units are arranged at an angle of 90°; a polyethylene membrane is adhered to both sides of the ballistic resistant layer with a solvent adhesive selected from the group consisting of styrene-ethylene-ethylene-propylene-styrene polymer, styrene-ethylene-butylene-styrene polymer and the mixture thereof; wherein said stab-resistant layer and ballistic resistant layer are located next to each other or form a sandwich structure with any other layer(s) placed between them, and said high strength and high module fiber has a strength of at least 32 cN/dtex and a modulus of at least 1000 cN/dtex.
