Abstract:
A composite article including fiber tows and a network including material drawn or pulled between the fiber tows. The network forms a physical barrier reducing propagation of cracks in the composite article. Exemplary structures described herein are the first to use a novel cellular architecture to toughen resin infused composites and create a continuous through thickness reinforcement that does not induce fiber breakage.

Claim (Index 14):
A method of manufacturing a composite article, comprising:\n forming a network of layers connected by pillars and coupling a plurality of plies, including:\n (a) depositing material from an outlet onto a base layer while moving the outlet and the base layer relative to one another, first in an x-y plane and then in a z-direction, so as to form an anchor on the base layer; \n (b) moving the outlet and the base layer relative to one another with no feed of the material from the outlet, so that a portion of the anchor is drawn to create one of the pillars; \n (c) moving the outlet and the base layer relative to one another so that the outlet is positioned above a next location on the base layer; \n (d) repeating steps (a)-(c) so as to create a plurality of the pillars on the base layer; \n (e) providing one of the plies comprising a plurality of fiber tows so that each of the plurality of the pillars pass through a different space between the fiber tows; and \n (f) coupling a layer to the plurality of the pillars so that the plurality of the pillars pass between the fiber tows before connecting with the layer; and \n repeating steps (a)-(f) using the layer as the base layer in the next step (a)_so that a composite article comprising the pillars, a plurality of the layers, and the plurality of the plies is made, the composite article comprising: \n the plurality of fiber tows; and \n the network comprising the layers connected by the pillars, wherein:\n each of the plurality of the pillars are drawn from one of the layers and pass through the different spaces between the fiber tows so as to connect the one of the layers to another of the layers, and \n the network forms a physical barrier reducing propagation of cracks in the composite article.
