Patent ID: 7419719

Claim:
A fabric product comprising: a fabric layer having a plurality of high strength and high modulus fibers, the plurality of fibers impregnated by an impregnation compound with the fabric layer coated on each side with the impregnation compound, where the impregnation compound is derived from a mixture comprising: a pre-polymer comprises an isocynate having an equivalent weight of 42, the pre-polymer having an isocynate content of 6.34; a co-reactant curative having an equivalent weight of 230; and a diluent, said diluent solvating the mixture of said pre-polymer and said curative, and wherein said impregnation compound has a curative stoichiometry range of less than 85 percent, wherein the high strength and high modulus fibers comprise at least one of aramid fibers or aromatic polyester fibers, wherein the ratio of said curative to said pre-polymer is derived from the formula 6.34 × 0.75 × 230 42 = parts ⁢ ⁢ by ⁢ ⁢ weight ⁢ ⁢ of ⁢ ⁢ curative ⁢ ⁢ per ⁢ 100 ⁢ ⁢ parts ⁢ ⁢ of ⁢ ⁢ pre ⁢ - ⁢ polymer wherein the pre-polymer comprises an isocynate and where 6.34 is the isocynate content of the pre-polymer, 0.75 is the desired stoichiometry of the mixture, 230 is the equivalent weight of the curative and 42 is the equivalent weight of the isocynate.
