Abstract
Methods of making fiber-resin compositions are described. The methods may include the providing of a thermoplastic resin to an extruder, where the thermoplastic resin may include at least one reactive moiety capable of forming a covalent bond with a coupling agent on a plurality of reactive fibers. The methods may further include combining the thermoplastic resin with the plurality of reactive fibers also supplied to the extruder. The reactive fibers are sized with the coupling agent that reacts with the thermoplastic resin to form the fiber-resin composition, which may be extruded from the extruder. Methods of making fiber-reinforced composite articles from the fiber-resin composition are also described.
