Abstract
A method for using a tow incorporating a large number of fibers to form a composite part that has the quality of parts made with tows incorporating a small number of fibers is described. The method includes spreading the tows incorporating a large number of fibers to form a relatively wide, flat, and continuous, unidirectional fabric, holding the fabric under tension to maintain the orientation and flatness, subjecting the flattened fabric to melt-bonding while held under tension to maintain the flattened configuration, and slicing the melt-bonded, unidirectional fabric into a plurality of narrow fiber tows and subsequently using these to produce braided, woven, and other fabric forms.
