Patent number: 11807352Abstract: A method for joining two substantially planar fiber-composite structural components, includes stacking the two components on a support jig to overlap along a joining region. A lower component end section within the joining region borders a gap between the upper component and the jig, where the upper component is unsupported by the jig. The gap is bordered on an opposite side of the lower component end section by a filling portion of the upper component or a planar filler element supported by the jig. The lower component is joined to the upper component within the joining region by applying temperature and pressure to the components. A width of the gap allows the upper component to elastically deform along the gap under the pressure and bend down into the gap to abut the jig along the gap and thereby compensate thickness tolerances between the components during the pressure application.Type: GrantFiled: August 8, 2022Date of Patent: November 7, 2023Assignee: AIRBUS OPERATIONS GMBHInventors: Andreas Poppe, Hermann Benthien, Thomas Beumler
