With the new product Alucoat, the company FibreCoat GmbH, Aachen/Germany, has launched an aluminum-coated glass or basalt fiber which is suitable as electro-magnetic shielding material in automotive applications such as radar, antennas or for autonomous driving as well as for mobile phones and applications in buildings.
Due to its extraordinary thermal conductivity and better heat transfer compared to traditional composite material, it can be used for the manufacturing of automotive battery trays or industrial applications such as fine particulate air filters.
As of November 1, 2020, FibreCoat, the start-up and spin-off of the Institut für Textiltechnik of RWTH Aachen University (ITA), Aachen/Germany, is part of a cooperation with AMAC GmbH (Advanced Materials and Consultancy), Aachen. Alucoat is available as of January 1, 2021, as a yarn, fabric or nonwoven material with a wide range of possible titers and areal weights. The material will offer an electrical conductivity of 100 Ωm and a working temperature of at least 400 °C. Furthermore, it can be used for the shielding of low to high frequencies with an effectiveness of 80-120 dB.
FibreCoat also develops metal-coated fibers like bi-component multi-filament yarns with basalt core and aluminum coating which can be used for EMI-shielding and heat sinks in battery casings, electric diverters in filters, reinforcement of cast aluminum parts or as conductive yarns in smart textiles.
FibreCoat has already won several international awards: the recent and famous „Falling walls venture“ award for advanced materials in Berlin/Germany for the most-promising science start-ups from across the world for the production of their innovative thermoplastic coated glass fibers.
