<p>Resin compositions useful for filament winding applications comprising an epoxy component including at least one polyepoxide resin curable by heat, an olefinically unsaturated monomer component including at least one polyolefinically unsaturated monomer curable by actinic radiation, at least one photoinitiator, at least one organic peroxide, and a heat activated curing agent. The compositions have a viscosity less than about 2000 centipoise (cps) and are capable of retaining this viscosity for at least about 2 hours at a temperature of from about ambient temperature to about 60 °C. The resin compositions may further include a cyanate ester component. The cyanate ester resin compositions have a viscosity less than about 2000 cps and are capable of retaining this viscosity for at least about 6 months at about ambient temperature. The resins are capable of being immobilized by actinic radiation exposure and further heat cured without substantial resin drip. One or more organic peroxides are employed, selected from the group of organic peroxides having 10 hour decomposition half lives at temperatures of from about 50 °C to less than about 104 °C. Also, fiber resin composites comprising fiber substrates impregnated with the dual-curing resin compositions. Also the process for coating fiber substrates with the dual-curing resin compositions is disclosed.</p> |
