High strength composite
First Claim
1. An article comprising at least one consolidated network of high strength fibers in a matrix composition, the high strength fibers having 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, wherein prior to consolidation the matrix composition comprises at least one thermoset vinyl ester, diallyl phthalate, and at least one carbon-carbon saturated solvent, said solvent being substantially removed during consolidation, and said thermoset vinyl ester having a tenacity of about 10,000 to 50,000 psi (6.9×
- 104 to 3.4×
105 kPa), a tensile modulus of about 1×
106 to 3×
106 psi (6.9×
106 to 2.1×
107 kPa), a TG of less than about 165°
C., and an elongation-to-break of about 2 to 1.4%.

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.
