Patent ID: 8636865

Claim:
A method for producing a composite component reinforced with a multiplicity of stiffening elements, wherein the stiffening elements are formed with a fibre reinforced, gluable thermoplastic material, comprising the following steps: producing a fully cured monolithic component having a fibre reinforced duroplastic material; producing thermoplastic stiffening elements; providing an inner tool, wherein the inner tool is a single piece and comprises at least in one region a multiplicity of rib-type recesses or beads which are adapted to receive the stiffening elements, wherein a cross-sectional geometry of the rib-type recesses or beads corresponds to a cross-sectional geometry of the stiffening elements to be inserted, and wherein surface geometry of an outer surface of the inner tool predetermines the inner theoretical geometry of the composite component to be produced; providing an outer tool, wherein the outer tool is adapted to receive the fully cured monolithic component and wherein the outer tool comprises an inner surface which forms an outer surface of the monolithic component; inserting the stiffening elements in the corresponding recesses of the inner tool; placing the fully cured monolithic component on the inner tool; inserting the fully cured monolithic component in the outer tool to increase pressing pressure and dimensional stability; and gluing the thermoplastic stiffening elements to the fully cured monolithic component with an adhesive; wherein the inner tool and/or the outer tool are heated to a temperature of between 125° C. to 225° C. to cure the adhesive, wherein the inner tool and the outer tool are loaded with pressure when the inner tool and the outer tool are pressed against each other during gluing of the stiffening elements, and wherein a tolerance compensation takes place between the stiffening elements and the shape-defining fully cured monolithic component.
