COMPATIBLE CARRIER FOR SECONDARY TOUGHENING

A process for manufacturing a composite article, which include combining a nonwoven mat of extruded fibers with one or more layers of fabrics to form a preform, and injecting the preform with a liquid thermosetting resin. The extruded fibers are formed by combining and extruding a thermoplastic carr...

Zusammenfassung:	A process for manufacturing a composite article, which include combining a nonwoven mat of extruded fibers with one or more layers of fabrics to form a preform, and injecting the preform with a liquid thermosetting resin. The extruded fibers are formed by combining and extruding a thermoplastic carrier material with a toughening material within a predetermined temperature range. The carrier material is immiscible with the toughening material, and the toughening material is encapsulated within the carrier material. The carrier material is at least partially soluble in the thermosetting resin within a predetermined temperature range, and the toughening material is insoluble in the thermosetting resin during a cure cycle. A preform having at least one nonwoven mat of extruded fibers is also disclosed.
