High strength composite
First Claim
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.

Abstract
An article made from at least one network of high strength fibers and a matrix composition that includes a vinyl ester and diallyl phthalate. Preferably, the article is made from at least one prepreg element which includes at least two adjacent layers of the high strength fiber network in the vinyl ester-containing matrix composition. The prepreg element is made by applying a mixture of vinyl ester, diallyl phthalate and a carbon-carbon saturated solvent to the high strength fiber network.
