Manufacturing thermoplastic composites and articles

A method of making a composite article, the method comprising:

• melting a reactive thermoplastic resin to form a molten reactive resin;
• fully impregnating a roving with the molten reactive resin in an impregnation device;
• polymerizing the molten reactive resin to form a first thermoplastic resin matrix in a polymerization device;
• cooling the first thermoplastic resin matrix to form a thermoplastic composite comprising fibers fully impregnated with the first thermoplastic resin matrix;
• mixing the thermoplastic composite with a second thermoplastic resin to form a mixture;
• and
• forming the composite article from the mixture.
