Zusammenfassung:	INSERTION OF CATALYST INTO DRY CARBON FIBERS PRIOR TO RESIN IMPREGNATION Systems and methods are provided for fabrication of enhanced carbon fiber laminates (150) that utilize encapsulated catalyst (524). One embodiment is a method that includes acquiring a batch of dry fibers (310), and acquiring a batch of catalyst capsules (410) that each comprise catalyst that accelerates polymerization of monomers of a resin, and a shell (520) that encapsulates the catalyst (524) and liquefies at a curing temperature. The method further includes interspersing the catalyst capsules (410) among the dry fibers (310), and impregnating the fibers (310) with the resin after interspersing the catalyst capsules (410) with the fibers (310).
