The company uses the aluminium-coated basalt fibres to produce short fibres, yarns and fabrics for electromagnetic shielding in electric vehicles, aerospace and buildings, among other applications.

FibreCoat founders Robert Brüll, Alexander Lüking and Richard Haas have succeeded in sheathing individual basalt fibres with aluminium in an economical process, reducing production costs to a fraction of those of conventional methods. “Our innovative high-performance fibres not only improve existing products,” as Brüll explains, “but also enable completely new EM shielding applications in electric vehicles or aerospace applications with lightweight, flexible fabrics. AluCoat also opens up completely new possibilities for smart textiles or shielding in buildings.”

The AluCoat product line includes chopped fibres and yarns that consist of up to 100 individual fibres, as well as woven or nonwoven fabrics. They are thermally and electrically conductive and temperature resistant up to 600 °C (1,100 °F). The material properties can be precisely adjusted via parameters such as the thickness of the coating or the diameter of the core fibres and adapted to customer-specific requirements. At the same time, FibreCoat’s coating technology offers significant quality and cost advantages in electromagnetic shielding compared to existing technologies such as pure aluminium fibres, aluminium foils or sheets.

FibreCoat wins competition

“And the winner is: FibreCoat!” was stated at the JEC Forum DACH in Frankfurt, Germany, at the end of November 2021. The start-up from Aachen won the “JEC Composites Startup Booster” competition there. Citing that FibreCoat “makes it possible to use cost-effective two-component materials in lightweight construction, electromagnetic shielding and industrial filtration.” This also qualified FibreCoat for the Startup Booster competition at JEC World 2022 in Paris.

The JEC World 2022 Startup Booster competition will take place on the Agora stage in Hall 5. FibreCoat is competing in the “Products & Materials” category. The finalists will present their pitches on May 3, from 10 am to 11:25 am. The awards ceremony will follow at 2:45 p.m. on May 4.
