Carbon fiber-reinforced thermoplastics (CFRTPs) are a promising candidate for future single-aisle aircrafts components. In order to compete with low-cost metal based solutions highly effective and flexible production technologies are required . Production systems for organic sheets and thermoforming, as well as automated fiber placement machines combined with autoclave consolidation are frequently used and readily available. However, there is a lack of systems capable of efficiently and flexibly producing 3D-curved, near net shaped preforms which undergo less reshaping during consolidation thus giving a better control over fiber angles.
At the Center for Lightweight Production Technology (ZLP) an automated process chain for advanced thermoplastic composites from as-delivered material to part assembly has been set up within an integrated work cell. In this work, we describe a smart manufacturing system that is capable of handling tailor-made individual cut-pieces that are stacked on top of one another already within the curved mold. An entire digital workflow from part design over automated cut-piece fabrication, generation of system related meta-information, virtual planning of the pick and place process to the final layup has been set up.
