Abstract
A method is provided of fabricating a composite stiffener having a curved web and at least one curved flange. A substantially straight length of unidirectional prepreg tape is placed on a carrier. The at least one curved flange is formed by using the carrier to steer a first portion of the tape onto a first curved tool surface. The curved web is formed by using the carrier to form a second portion of the tape onto a second curved tool surface.
