Abstract
A method useful for forming a composite part having regions in which fibers align with the principle stress vectors as well as regions having a randomized fiber alignment. To form the randomized fiber alignment, a preform cavity is formed in a preform arrangement, and the preform arrangement is molded in accordance with compression molding protocols to form a part.
