Three dimensional printed fibrous interlocking interlayers

Abstract:

A three dimensional permeable thermoplastic tape useful for joining of layers of fiber tows (plies) together so as to form highly toughened resin infused structures. In one or more embodiments, the tape is manufactured using three dimensional printing and is applied between layers of fiber tows so as to tack the layers of fiber tows in place and prevent movement of the layers of fiber tows.
