Title: (EN) Process for producing a substantially shell-shaped component
Abstract: front page image
(EN)

Disclosed is a process for producing a substantially shell-shaped component, from substantially carbon-fiber-reinforced synthetic material having at least one local reinforcing zone and at least one stiffening element, in particular a fuselage shell, a wing shell, a vertical stabilizer shell or horizontal stabilizer shell of an aircraft or the like. The process according to the invention comprises the following steps:

    • arranging at least one doubler which has already been cured, on an at most partially cured shell skin to form the local reinforcing zone,
    • applying at least one stiffening element which has already been cured, and
    • placing at least one at most partially cured connecting angle bracket against the at least one stiffening element at least in the region of the at least one doubler, and
    • curing the shell skin and the connecting angle bracket.
