Apodius GmbH (Aachen, Germany) has introduced the Apodius vision system (AVS), a modular, production-integrated inspection system for composite structures in general and the production of textile fabrics in particular. It provides measurement results starting with the fiber and ending with the finished composite product. Quality characteristics of composite components are measured during layer buildup and used for process control in automation. Captured geometries are wrapped with the component surface texture. Fiber orientations are calculated, compared to reference values and provided in a 3D model for return in simulation or engineering software. Apodius Vision Systems detects production faults via actual-vs.-theoretical comparison. The basic AVS version visually measures the fiber angle of semi-finished textiles and preforms with a resolution of 0.1°. The measuring data is analysed with a frequency of 10Hz and is reportedly robust enough to resist extraneous light and conductive fiber dust. For the use of measuring data, interfaces for data storage and connections to process automation elements like robots are provided.
