Abstract
A method of fabricating a structural member having a stiffener bead therein. Prepreg plies or layers of high tensile strength fabric are laid up on a conformable caul plate. A rubber-like plug is prefabricated to the shape of the stiffener bead and is urged into a stiffener bead cavity of the caul plate by a metal tool to sandwich the prepreg plies between the caul and the plug. The caul and the plug cooperate to cause the prepreg plies to conform to the desired shape of the stiffener bead.
