FAVILEIT: A testing machine for the simultaneous characterization of mechanical and electrical properties of fibres and yarns for technical textiles
Tensile test of a fibre in the FAVIMAT+
The Institute of Lightweight Engineering and Polymer Technology has started the two year ZIM-project FAVILEIT in cooperation with the Textechno Herbert Stein GmbH & Co. KG. The project goal is to develop a standardized and commercially available testing machine for the simultaneous characterization of mechanical and electrical properties of conductive fibres and yarns, by which the electrical conductivity in dependency of the mechanical stretch can be characterized.
The rapid development of the smart textiles sector enables a new dimension of functional integration and creates the preconditions of an innovative design of the future. Next to the usage in consumer goods like heated clothing, technical e-textiles with integrated electronic and sensory functions can be designed. Such textiles can be used widely. An enhanced fibre composite component with sensory functions enables monitoring the conditions of critical structural components (SHM) and damage detection in an early stage.
For the selection and development of suitable fibre materials, the electrical and mechanical properties of the fibres have to be known. Currently, there is no testing machine for a combined determination of these properties standardised or commercially available. The FAVILEIT-Project wants to close this gap in cooperation with the Textechno Herbert Stein GmbH & Co. KG within a two year ZIM-Project. Under the lead of Prof. Dr.-Ing. Niels Modler (professorship of lightweight engineering and polymer technology), a suitable method of testing for the simultaneous characterisation of mechanical and electrical properties of conductive fibres in a single machine will be developed and implemented in the worldwide leading fibre tester FAVIMAT+. Within the second project stage, the developed technology is supposed to be implemented in the automatic yarn tester of the STATIMAT series.
The project is financed by the Zentrale Innovationsprogramm Mittelstand (ZIM) des Bundesministeriums für Wirtschaft und Klimaschutz (BMWK) for the duration of two years (April 2021 – March 2023).
