Patent ID: 8580170

Claim:
A process for producing a substantially shell-shaped component from fiber-reinforced synthetic material having at least one local reinforcing zone and at least one stiffening element, the process comprising the steps of: arranging at least one doubler made of a fiber-reinforced synthetic material which has already been fully cured, on a shell skin made of a fiber-reinforced synthetic material being at most partially cured to form a local reinforcing zone, applying at least one stiffening element made of a fiber-reinforced synthetic material which has already been fully cured, the at least one stiffening element having a recess receiving the at least one doubler, and placing at least one connecting angle bracket made of a fiber-reinforced synthetic material being at most partially cured against the at least one stiffening element at least in the region of the at least one doubler, introducing a structure constituted by the shell skin, the at least one doubler, the at least one stiffening element and the at least one connecting angle bracket into a vacuum bag, which is moved into an autoclave for curing, and curing the shell skin and the connecting angle bracket at a temperature of between 120° C. and 180° C. and a pressure of up to 10 bar in the autoclave to produce a finished shell-shaped component, wherein the at least one connecting angle bracket is bonded to the at least one stiffening element and to the at least one doubler.
