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.
