Curing-Transponder

The continual and consequent raising of the resource efficiency during production and using polymer fibre-reinforced composites is mandatory in order to maintain the competi-tive position of Germany in this industry. (It is imperative to continually and consequently raise the resource efficiency during producing and using polymer fibre-reinforced compo-site components in order to maintain the competitive position of Germany in this production field.) To support this, the project aims at several issues during the production cycle of polymer fibre-reinforced composite components and uses the RFID (radio frequency identi-fication) technology as base for intelligent optimization. The goal of this research project is the development of a RFID curing transponder, which can be integrated into composite components and their moulds, to gain online and in situ information about the degree of cure of the polymer matrix (curing monitoring). The measurement method should also provide data on the resin flow front during infusion and injection processes in real time al-lowing for a detailed picture on the resin filling state in the preform and the degree of cure. This specific information should be stored on the transponder chip, so that it can be used for process analysis and optimization. Furthermore, the innovative transponder should store important information and keep it ready throughout the entire life cycle of the component in a digital file. For example, this file, which is integrated into the component, will significantly simplify the required proof of quality, recognition of plagiarism, logistics and the manage-ment of replacement parts for the user…read more
