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.

This invention relates to an adhesive joint for joining components of transport craft, in particular of aircraft, wherein the adhesive joint is formed by an adhesive means. According to the invention, the adhesive means has several functional elements with actuatory and/or sensory properties, in particular for enabling a minimum mechanical load capacity of the adhesive joint and/or detecting a mechanical loading state in the adhesive joint. Due to the presence of functional elements integrated in the adhesive joint direct and simple testing of the mechanical load capacity of the adhesive joint is possible without costly external test structures, e.g. in the form of measuring and testing systems for conducting tensile load tests or the like. Moreover, mechanical stress states in the adhesive joint can be detected. Moreover, the invention relates to a method for determining a minimum mechanical load capacity and/or mechanical strength of an adhesive joint.

This invention provides a method for producing a structural component, particularly in the aerospace sector. An unhardened prepreg fabric is formed from a composite fiber material, hardenable at a first hardening temperature, into a predetermined shape. The unhardened prepreg fabric is then connected to at least one hardening part of a composite fiber material partially hardened at a second hardening temperature for holding the unhardened prepreg fabric in the predetermined shape, wherein the second hardening temperature is lower than the first hardening temperature. In a further method step the unhardened prepreg fabric connected to the at least one holding part is hardened at the first hardening temperature to form the structural component. The idea on which this invention is based consists in replacing expensive tools of special steel previously used for holding dimensionally unstable prepreg fabrics with at least one holding part of composite fiber materials, wherein the at least one holding part has a lower hardening temperature than the prepreg fabric, and can therefore be produced with a lower cost tool.
