A semi-finished product arrangement for producing a fiber composite component by molding a planar semi-finished fiber composite product in a molding tool is provided. The arrangement includes the semi-finished fiber composite product and multiple holding elements fixed in place thereon and each extending beyond the edge of the semi-finished fiber composite product. The holding elements are countersunk in recesses of the semi-finished fiber composite product, in order to avoid a projection in terms of height.

A non-destructive determination of material characteristics of an aircraft component is provided. To provide a simple determination of material characteristics, which can be implemented economically, it is provided to make available image data of a layer, which can be detected from outside using electromagnetic radiation, of a workpiece to be examined; to detect first areas having a first pixel characteristic using the image data; and to detect second areas having a second pixel characteristic using the image data; the first pixel characteristic being associated with a fiber inlay of a fiber composite layer; and the second pixel characteristic being associated with an at least part-crystalline thermoplastic polymer of the fiber composite layer, which thermoplastic polymer is in a crystalline state; and to determine a relationship of the first areas to the second areas.

Non-destructive determination of material characteristics

A method and a device for inspecting the quality of a formed thermoplastic fiber-reinforced plastic component wherein the component is tested by means of a sensor unit with a downstream electronic evaluation unit for analysis of the measuring result acquired by sensor technology by means of sample comparison, wherein by means of the optical sensor unit the surface roughness of the plastic component is measured after forming, which surface roughness is analyzed by means of the evaluation unit by a comparison with a stored reference pattern in such a manner that increased surface roughness is interpreted as increased internal materials porosity.

The invention relates to a device for the production of an angle for connecting a fuselage cell skin to an annular former and/or a stringer inside a fuselage cell structure of an aircraft, the angle taking place by the one-step deformation of an initially planar blank along at least three fold lines in a uniaxial compression molding device. A mounting frame with hinges is arranged in the compression molding device, the blank to be deformed being accommodated along the edges preferably by means of a plurality of peripherally arranged springs. A deformation of the blank into an auto-stabilized angle is possible in one step while simultaneously ensuring interlaminar slide. Due to the constructively conditioned auto-stabilization of the angle, additional components which increase the weight and the assembly effort (so-called 'stabilos') in the connection region between fuselage cell skin, stringers and annular formers inside a fuselage structure of an aircraft are unnecessary.

Device for producing a component and method and component

The invention relates to a method for producing a component for connecting a fuselage cell skin to an annular rib of an aircraft, wherein the component is formed by bending of a flat blank along at last two edge lines and wherein the blank is formed by a CFRP. According to the invention the interlaminar sliding of the fiber layers is largely completed in a first forming step, while in a second forming step a consolidation of the component takes place by the use of pressure from the press on all sides by means of an upper tool and a lower tool. This enables complex components with at least two edge lines to be produced, which edge lines run at angles of approximately, preferably at angles of 309&#xb0; to 90&#xb0;, to each other, and which edge lines also lie in at least two different planes.
