METHOD OF MANUFACTURING AT LEAST ONE LONGARIN COMPONENT, LONGARIN COMPONENT, PRODUCT INCORPORATING LONGARIN COMPONENT, UNLINDER CYLINDER COMPONENT According to one aspect, the present invention relates to at least one non-uniform thickness composite stringer member 152. The method comprises braiding 202 a plurality of fibers 126 into a non-cylindrical mandrel 140 to form a variable preform fiber preform 150, flattening the pre fiberform 150 and cut the flattened fiberform preform 150 to obtain at least one composite member of non-uniform thickness 152. The stringers 152 made in accordance with numerous embodiments of the present invention are of faster manufacture. and economical than conventional composite stringer components.
