Abstract

A method of fabricating a composite part with integral structural details is provided. Fibrous material may be wrapped on a detail surface and an interface surface of a first detail mold. Fibrous material may also be wrapped on a detail surface and an interface surface of a second detail mold. Fibrous material may also be laid on a molding surface of a tool mold to form a control surface of the part. The first and second detail molds may be arranged on the molding surface of the tool mold to form the details. In particular, fibrous material wrapped on the detail surfaces of the first and second detail molds may be disposed adjacent to each other, and fibrous material wrapped on the interface surfaces of the first and second detail molds may be disposed adjacent to the fibrous material laid on the molding surface. Resin is flowed into the detail molds via inlet ports and through integral resin channels into the fibrous material. The resin flowed through the fibrous material laid on the tool mold and the fibrous material wrapped on the detail molds are co-cured to unitize the stiffeners and the details integrally formed with the part.
