FibreCoat

FibreCoat is a German materials company that makes hybrid fibres by coating glass and basalt filaments with metal or polymer. Its website calls the result the smallest reinforced composite in the world and describes bi-component multi-filament yarns with a basalt or glass core and a metallic sheath, as well as an E-glass core with a polypropylene sheath. The idea of coating fibres emerged in 2014 during Robert Brull's doctoral research at the Institute for Textile Technology at RWTH Aachen University.

Products and benefits

• Aluminium- and polymer-coated fibres used for EMI shielding, thermal conductivity, fire resistance and other functions
• PolyCoat, launched for thermoplastic composites
• Material combinations that can be adjusted to specific needs
• Lightweight yet strong materials, with reduced energy consumption, less material waste and lower production costs

After the COVID-19 pandemic disrupted supply chains and halted production, the company turned to aluminium coating, which early results showed to be promising. Its engineers explain how they coat glass fibres at the filament level to create hybrid fibres with high functionality at high speed and low cost.

Defence and space

FibreCoat has unveiled chaff payloads for air and UAV platforms and writes about making chaff for long-range drones, which it argues need to survive modern air defences. It is developing fibres for space applications that can improve radiation shielding, EMI protection and composite structures, and reported taking its technology to space as a major commercial milestone. Its FibRaShield product won first place in the industry category at INNOspace Masters 2025, and the EIT RawMaterials-backed company was named among Time Magazine's Best Inventions of 2025.
