Abstract
The fibers constituting the composite material are impregnated with a composition containing at least one unsaturated epoxy resin mixed with at least two ethylenic monounsaturation monomers, at least one ethylenic polyunsaturation monomer, a photoinitiator and an organic peroxide. The composition is prepolymerized by means of ultraviolet rays in a first step and then cross-linked either by ultraviolet rays or a temperature rise in a second step.
