  • Method of forming flyaway stringer end caps
    Patent number: 11806948
    Abstract: Systems and methods are provided for utilizing stringer end caps. One embodiment is a method of forming a stringer. The method includes laying up a stringer preform comprising fiber-reinforced material, placing the stringer preform onto a skin panel preform, bonding an end cap to the stringer preform and the skin panel preform, and co-curing the stringer preform and the skin panel preform while the end cap is bonded to the stringer preform and the skin panel preform, resulting in a composite part that includes the end cap.

  • Stringer Manufacturing System Using a Caul
    Publication number: 20230219308
    Abstract: A method, apparatus, system, and computer program product for fabricating a composite part. Composite materials are laid up on a mandrel. A caul is placed over the composite materials laid up on the mandrel. An inner mold line of the caul is sized to an outer surface of the composite materials in a cured state. The composite materials laid up on the mandrel with the caul over the composite materials is cured to form the composite part. The composite materials expand to the inner mold line of the caul during curing of the composite materials to form the composite part.
