摘要： A positioning system for detecting a spatial position of a laying head of a device for automatically laying reinforcing fiber strips in relation to a base on which the reinforcing fiber strips can be laid by the laying head includes at least two laser lines which extend substantially in parallel at a spacing A from one another and substantially transversely to a laying direction can be projected on the laid reinforcing fiber strips by at least one laser source. The elevation profiles of the projected laser lines which occur on account of an irregular surface of the laid reinforcing fiber strips are able to be recorded by a camera and supplied to an evaluation unit.

摘要： A device for consolidating a thermoplastic preform, in particular a carbon fiber thermoplastic preform includes a heating element, e.g., an LED array, for heating the preform and a consolidation element, e.g., a consolidation roller, for exposing the preform to pressure and for cooling the preform. In order to consolidate the preform, the heating element and consolidation element are arranged and movable relative to each other in such a way that the preform can be exposed to pressure and cooled by the consolidation element after heated by means of the heating element.

摘要： In order to provide a simplified inspection of an aircraft for the pilot, an aircraft inspection system is provided which includes at least one movable inspection unit, a position detection arrangement, and at least one data transfer interface. The at least one moveable inspection unit is moveable relative to an aircraft to be inspected. The at least one movable inspection unit includes at least one sensor for detecting a characteristic value, for verifying a characteristic and/or for determining a defect of an aircraft. The movable inspection unit is configured to generate monitoring data. When a defect or a characteristic value is detected, the position detection arrangement detects position data of the movable inspection unit in relation to the aircraft to be inspected, and assigns the position data to the monitoring data. The data transfer interface provides the position data with the assigned monitoring data as inspection data.

摘要： A device for the layer-wise additive production of a complex three-dimensional component has a measuring mechanism for continuously monitoring quality indicators during the production of the component, wherein the measuring mechanism and a bed with a material powder are surrounded, at least in regions, by a processing cell filled with a protective gas atmosphere and the material powder of an uppermost layer can be melted in a locally limited manner in a melting zone by means of at least one laser. The measuring mechanism has the at least one laser and at least one optical sensor for the priority detection of the quality indicators in the region of the melting zone, in particular by means of Raman spectroscopy. Consequently, any construction errors in the component can be recognised, evaluated and, if necessary, corrected in a resource-saving manner without delay.

摘要： The invention relates to a device for the infiltration of fibrous material with resin for the production of a fiber composite component, comprising a mold tool with a cavity enclosed by at least two tool parts, wherein the mold tool is designed for a relative movement of the at least two tool parts, in such a manner that space can be provided inside the cavity, in a first tool position, to hold the fibrous material, and additional space can be provided to accommodate resin, and the size of the cavity can then be reduced by a movement of the mold tool from the first tool position into a second tool position. According to the invention, a flow promoter is included in the cavity, comprising at least one first layer and one second layer, connected to each other in an edge region of the flow promoter to enclose a flow space, wherein the first layer is impermeable to resin while the second layer provides an outlet for guiding resin out of the flow space and into the fibrous material, and wherein the flow space of the flow promoter is filled with resin and/or the flow promoter has an inlet for conveying resin into the flow space. The invention further relates to a corresponding infiltration process and to a use of the device and/or the method.
