Center for Textile Lightweight Engineering

Technical Equipment

On an area of over 1,500 m², the Center for Textile Lightweight Engineering combines classic textile technology and innovative systems for composite production. The technical equipment on a semi-industrial scale enables both small pre-trials and the production of small series. The installed equipment in the research and test field are linked with a process control system, so that comprehensive data acquisition and evaluation is possible. The combination with the recorded consumption data, such as electricity, gas and compressed air consumption, as well as the environmental conditions, enables ecological and economic assessments of the done developments.

Projekt VliesSMC

Im Januar 2021 wurde nach 10-monatiger Projektlaufzeit der 2. Projektbegleitende Ausschuss im AiF-Vorhaben-Nr. 21124 BG „VliesSMC“ erfolgreich durchgeführt. Mit den virtuell anwesenden 16 Partnern aus Industrie und Forschung diskutierten die Forschungsstellen die Ergebnisse der ersten Versuchskampagne zur Vliesstoff- sowie SMC-Herstellung. Insbesondere offene Fragestellungen hinsichtlich der unterschiedlichen textilen Herstellungsprozesse, der Herstellung und Handhabung der SMC-Halbzeuge, wie auch der Fließfähigkeit im Pressverfahren wurden adressiert.

Projekt HPF-Garnitur


11/2019-10/2021

Bei der Verarbeitung von Hochleistungsfasern zu Vliesstoffen tritt vor allem an den metallischen Arbeitselementen, z.B. Garnituren der Krempel, eine erhöhte Abrasion auf. Diese führt zu vorzeitigem Verschleiß der Garnituren und erhöhten Prozesskosten. Um diese Situation zu verbessern wird im Rahmen des Projektes „HPF-Garnituren“ sowohl die Garnitur hinsichtlich ihrer Materialoberfläche und Zahnung optimiert, als auch ein digitales Monitoringsystem zur Überwachung des Abnutzungsgrades entwickelt.
