Abstract (englisch):

Beads are widely used to stiffen sheet metal components subjected to bending loads.
Often, these bead-stiffened parts are used in product variants that differ significantly in the
amount of acting loads. Lamination of unidirectional carbon fibre reinforced plastic (UD-CFRP)
on the top flange area of individual beads represents a method for further increasing weight-
specific stiffness: By varying the number of plies, a specifically configured component is
obtained for each of the load cases. As a result, no changes to the forming tools are necessary
and a minimum amount of the UD-CFRP material is required. In this work, a complete
manufacturing process for a fibre reinforced bead was developed: First, a bead cross section
geometry with an adapted top flange area to accommodate the UD-CFRP plies was designed
and stamped into pre-stretched sheet samples of DX56 steel. Subsequently, the suitability of
several surface pre-treatment processes to achieve sufficient bond strength of the composite
bead was experimentally investigated and the UD-CFRP plies were applied by lamination. ... mehr
