Abstract
Methods of making fiber-containing prepregs are described. The methods may include the steps of providing a plurality of fibers, and applying a reactive resin composition to the plurality of fibers to make a mixture of the plurality of fibers and the resin composition. The reactive resin composition may include at least one of monomers and oligomers capable of polymerizing into a polymerized resin matrix. The mixture may be heated to a polymerization temperature where the monomers, oligomers, or both polymerize to form a fiber-resin amalgam that includes the polymerized resin matrix. The fiber-resin amalgam may be formed into the fiber-containing prepreg. Also described are methods of forming a fiber-reinforced composite that includes the prepreg.
