Patent ID: 7226878

Claim:
A ballistic material for dissipating the kinetic energy of a moving object comprising a fabric which further comprises a shear thickening fluid intercalated into a fabric and/or yarn wherein said shear thickening fluid (STF) remains in a fluid form, and wherein said shear thickening fluid comprises inorganic particles suspended in an organic or silicon based solvent, wherein said solvent comprises ethylene glycol, polyethylene glycol, a silicon oil or phenyltrimethicone or mixtures thereof; and wherein said particles are oxides, calcium carbonate, synthetically occurring minerals, naturally occurring minerals or a mixture thereof, and said solvent is environmentally stable and remains integral to said material and said suspended particles during service, and said STF is present in an amount from 0.13 grams to 6.3 grams/per gram of ballistic material; wherein said ballistic material contains aramid fibers, graphite fibers, nylon fibers, glass fibers or poly (para-phenylene terephthalamide) fibers.
