Claim Text:
1. A method of forming a curable pre-impregnated composite precursor material, the method comprising: heating an uncured resin composition to a first temperature so that the uncured resin composition exhibits a first dynamic viscosity of less than or equal to about 5,000 centipoise (cP), wherein the uncured resin composition is curable by actinic radiation or electron-beam radiation and comprises: (a) an acrylate or a methacrylate monomer having two or more functional groups; and (b) an oligomer species selected from the group consisting of: polyethers, polyesters, epoxies, and combinations thereof; applying the uncured resin composition to a fiber-based substrate material; and cooling the uncured resin composition disposed on the fiber-based substrate material to form the curable pre-impregnated composite precursor material, so that the uncured resin composition exhibits a second dynamic viscosity of greater than or equal to about 200,000 cP to less than 1,000,000 cP at room temperature of about 21° C. (70° F.).
