摘要： A method for a probabilistic detection of defects in ribbons of material laid on a fiber composite workpiece. The method includes detecting at least one surface profile of a workpiece having laid material ribbons and locating a surface profile entry in a database. In this case, the surface profile entry provides an assignment of the surface profile to a defect type and to a hit probability that the detected surface profile is based on a defect of the defect type.

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 fiber application tool for a fiber placement and production method has a fiber contact surface area, which has a fiber contact surface for applying and/or pressing the fibers onto a work surface. The tool further includes an activation device for activating an adhesive, matrix, resin, or binder material provided at the fibers by means of an activation radiation so that the fibers are tacked onto the work surface. The fiber contact surface area for the activation radiation may be transparent and that the activation device may be designed so to guide and/or deliver the activation radiation through the transparent fiber contact surface area to the fibers to be pressed by the fiber contact surface.

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： Devices and methods are disclosed for depositing reinforcing fiber tapes and detecting laying errors. Automatic depositing of reinforcing fiber tapes on a support can occur by a laying head and at least one roller assigned to the laying head. At least one radiation source and/or at least one sensor is integrated into the at least one roller for the detection of laying errors, and this roller is transmissive at least by region for a radiation emitted by the radiation source.
