1. A method for producing a ballistic resistant article that includes at least one network of high strength fibers in a matrix composition, wherein the high strength fibers have a tenacity of at least about 7 g/d, a tensile modulus of at least about 150 g/d and an energy-to-break of at least about 8 J/g, the method comprising applying a mixture consisting essentially of at least one thermoset vinyl ester, an optional catalyst for curing the thermoset vinyl ester, diallyl phthalate and at least one carbon-carbon saturated solvent having a boiling point lower than about 115°

  • C. to a high strength fiber network followed by consolidating the coated high strength fiber network at a temperature higher than the boiling point of the solvent and lower than about 120°

    C. to substantially remove the carbon-carbon saturated solvent.
