Abstract
An apparatus and method of forming a stringer or an integral stringer and fuselage skin. The apparatus may be a solid bladder made of silicone, urethane, or any similar material or combination thereof. The method may comprise placing composite material onto a surface of a tooling having a channel sized and shaped to correspond to a desired stringer size and shape. Then the solid bladder may be placed onto the composite material relative the channel. The shape of the solid bladder may correspond to the shape of the channel. Composite material may then be placed over the solid bladder, vacuum-sealed against the bladder and the tooling, and cured to harden the composite material, thereby forming a stringer or an integral stringer and fuselage skin.
