A composite article including a plurality of layers each comprising bundles of fibers separated by spaces; pins bonded to a side of at least one of bundles and extending or built through the spaces between the layers; and a resin combined with the layers and the pin. The pins form a physical barrier preventing or reducing propagation of cracks in an x-y plane of the composite article.
