Abstract: Methods of forming a curable pre-impregnated composite precursor material with radiation (e.g., actinic or electron-beam) curable resin composition systems are provided, as are the curable pre-impregnated composite precursor materials themselves. The resin systems have reversible temperature-viscosity control, which are advantageously used to form curable pre-impregnated composite precursor materials (pre-preg) that can be cured to form a composite article. The uncured resin composition comprises: (a) an acrylate or a methacrylate monomer; (b) an oligomer species selected from the group consisting of: polyethers, polyesters, epoxies, and combinations thereof; and (c) a photoinitiator. The uncured resin has a first viscosity at 21° C. (70° F.) of ≧about 200,000 centipoise (cP) and a second viscosity of ≦about 5,000 cP at 65° C. (149° F.) or above.
