Claim 0:
1. A textile with increased resistance to puncture, cutting, abrasion, and/or dust penetration, the textile comprising:
(1) a fabric comprising a plurality of fibers comprising a tensile strength of at least about 250 MPa, wherein the plurality of fibers comprise a three-beam weave with one surface of ePTFE interwoven into a second surface of poly-(m-phenylene isophthalamide) interlaced with a poly-(p-phenylene terephthalamide) lattice or a two-beam weave with one surface of ePTFE interwoven into a second surface comprising aromatic polyester fibers produced by polycondensation of 4-hydroxybenzoic acid and 6-hydroxynapthalene-2-carboxylic acid and poly-(p-phenylene terephthalamide; and
(2) a shear thickening fluid comprising at least one low volatility carrier fluid comprising a vapor pressure of less than about 1×10−6 mPa at 25° C. in which is suspended particles having an average particle size of less than about 4,000 nm;, wherein the particles are suspended in the low volatility carrier fluid at a concentration in the range from about 40% to about 85% by weight particles, wherein the shear thickening fluid is intercalated into the fabric, and wherein the shear thickening fluid confers to the fabric increased resistance to puncture, cutting, abrasion, and/or dust penetration as compared to an equivalent fabric that is not intercalated with shear thickening fluid.
