Abstract

Methods of making fiber reinforced composite articles are described. The methods may include the step of providing a pre-impregnated fiber-containing thermoplastic material to a mold for the article. The pre-impregnated fiber-containing thermoplastic material may include: (i) a plurality of fibers, and (ii) a first thermoplastic polymer made from a first reactive thermoplastic resin. Reactants of a second reactive thermoplastic resin may be introduced to fill open spaces in the mold that are left by the pre-impregnated fiber-containing thermoplastic material. The second reactive thermoplastic resin may then be polymerized to form a second thermoplastic polymer. The final fiber reinforced composite article includes at least two spatially distinct regions of thermoplastic polymer.
