Methods of making a fiber-containing prepregs are described. The methods may include the steps of drawing unsized fibers from a batch of molten glass, applying a sizing composition to the unsized fibers to form a plurality of sized fibers, weaving the plurality of sized fibers into a fabric. Another step may include melting a reactive resin composition to form a melted reactive resin composition, where the reactive resin composition may include caprolactam. The melted reactive resin composition may be applied to the fabric. The method may further include heating the fabric and the melted reactive resin composition to a polymerization temperature, and forming the fiber-resin amalgam into the fiber-containing prepreg. In other embodiments, the methods may include the steps of providing a plurality of fibers, 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. |
