Abstract

A method for the manufacture of a fiber composite component reinforcement section, which bounds a cavity, whereby a supporting core, with an elastic sleeve bounding an interior space, is temporarily positioned in the cavity. The steps include: laying down fibrous material on a base molding tool to form a base element of the fiber composite component, draping fibrous material in a negative mold, arranging the supporting core on an inner surface of the fibrous material in the negative mold, positioning the negative mold fitted with the fibrous material and the supporting core, on the base element to form the reinforcement section, forming a vacuum chamber accommodating the negative mold and the base element by covering with a vacuum film, evacuating the vacuum chamber, and curing the fibrous material, whereby when using a dry fibrous material, a matrix material is injected into the fibrous material after the evacuation.
