Abstract:
Composite tooling systems and methods of manufacturing composite stringers of aircraft are provided herein. A composite tooling system includes a layup tool and an articulating stringer mandrel. The layup tool has a contoured surface with portions having different surface complexities. The articulating stringer mandrel includes two rigid mandrel elements and a cable. The first rigid mandrel element defines a first aperture, a first stringer surface, and a first bottom surface. The second rigid mandrel element is adjacent to the first rigid mandrel element and defines a second aperture, a second stringer surface, and a second bottom surface. A first length of the first rigid mandrel element cooperates with the surface complexity and a second length of the second rigid mandrel element cooperates with the surface complexity at the second rigid mandrel element so that a gap between the rigid mandrel elements does not exceed a predetermined gap threshold.

Claim (Index 17):
An articulating stringer mandrel for a composite tooling system, the articulating stringer mandrel comprising:\n a first rigid mandrel element defining a first cavity having a first cavity surface at an end of the first rigid mandrel element; a second rigid mandrel element defining a second cavity having a second cavity surface at an end of the second rigid mandrel element opposing the first cavity of the first rigid mandrel element; a mandrel ball disposed at least partially within the first cavity of the first rigid mandrel element and at least partially within the second cavity of the second rigid mandrel element, the mandrel ball defining a first pivot surface and a second pivot surface, wherein the first pivot surface opposes and has substantially a same shape as the first cavity surface of the first rigid mandrel element and the second pivot surface opposes and has substantially a same shape as the second cavity surface of the second rigid mandrel element; and a cable having a relaxed state and a tensed state, wherein the relaxed state permits the first rigid mandrel element and the second rigid mandrel element to pivot with respect to each other about the mandrel ball, and wherein in the tensed state the cable tightens the articulating stringer mandrel to compress the first rigid mandrel element, the mandrel ball, and the second rigid mandrel element.
