摘要 According to one aspect, the present invention relates to a method of manufacturing at least one non-uniform thickness composite spar component. The method comprises braiding a plurality of fibers over a non-cylindrical mandrel to form a variable thickness shaped fiber preform, flattening the shaped fiber preform and cutting the flattened shaped fiber preform to obtain the at least one non-uniform thickness composite spar component. Spars made according to various embodiments of the present invention are faster and less expensive to manufacture than conventional composite spar components.
