FibreCoat

What FibreCoat does

FibreCoat GmbH is a German materials technology company headquartered in Aachen that develops and manufactures patented metal- and polymer-coated fibers for demanding industrial applications. The company's core innovation is a continuous fiber spinning and coating process that applies metallic or thermoplastic sheaths to basalt or glass fiber cores in a single production step, producing bi-component multi-filament yarns with tunable electrical, thermal, and mechanical properties. Two primary product families underpin the portfolio: AluCoat (aluminum-sheathed basalt/glass fibers used for EMI shielding, thermal conductivity, fire resistance, and radiation protection, with reported shielding of 40-95 dB and tensile strength of 1.5 GPa) and PolyCoat (polypropylene-sheathed E-glass fibers for high-volume thermoplastic composites). Supporting products include FibRaShield for space radiation shielding, MoonFibre for an ESA-funded lunar regolith fiber program, proprietary chaff cartridges (FC-RR-170, FC-RR-26, FC-RR-50) for radar countermeasures, and AluBas Tape co-developed with A+ Composites.

The company generates revenue through a mix of one-time product sales (coated fibers in yarn, chopped, woven, and non-woven formats; finished chaff cartridges), professional R&D services (feasibility studies, pilot-line access, application engineering, multi-year contracts), and licensing arrangements such as the MoonFibre technology partnership with ESA. Sales go directly to enterprise customers in defense, space, automotive/EV, construction, and industrial sectors via field sales, sample-based qualification, and trade-show demonstrations (e.g., JEC World 2026). Manufacturing is distributed across four production sites in Germany, Georgia, the Czech Republic, and Poland, using modular spinning lines designed to be deployable at partner sites within two weeks at low capital intensity. Pricing is quote-based and not publicly disclosed.

FibreCoat was founded in 2020 by Dr. Robert Brüll (CEO), Richard Haas (COO), and Alexander Lücking, building on Brüll's doctoral research at RWTH Aachen University's Institute for Textile Technology. The company is private and venture-backed, having raised approximately $25.4 million cumulatively across an EXIST federal seed grant (2018), a $3 million round in 2021, and a €20 million Series B in December 2024 led by GOOSE Capital and NewSpace Capital with strategic participation from Saint-Gobain NOVA, to scale production for space and defense customers. The 50-employee team operates without subsidiaries under a founder-led management structure that also includes dedicated Heads of Business Development, R&D, Operations, People & Admin, and Finance.

Core offering

FibreCoat develops and manufactures bi-component multi-filament fibers with metallic (aluminum, tin, zinc, bismuth, nickel, copper, brass) or thermoplastic polymer sheaths over basalt, glass, or E-glass cores, produced through a patented continuous spinning-and-coating process. Products are sold in yarn, chopped, woven, and non-woven formats for EMI shielding, radiation protection, radar countermeasures, EV battery enclosures, and thermoplastic composites. The company also offers custom R&D services and application engineering across four production sites in Germany, Georgia, the Czech Republic, and Poland.

Product overview

FibreCoat offers two primary product families: metal-coated fibers (AluCoat) and polymer-coated fibers (PolyCoat), both based on a patented coating technology that applies metals or thermoplastics to fibers during the spinning process. AluCoat provides aluminum-coated basalt/glass fibers with EMI shielding up to 85 dB, thermal regulation, and radiation protection, available in yarn, chopped, woven, and non-woven formats. PolyCoat extends the technology to thermoplastic polymers for high-volume composite manufacturing. Supporting products include AluBas Tape (with A+ Composites), FibRaShield radiation shielding, MoonFibre lunar regolith fibers (ESA project), and chaff cartridges (FC-RR-170, FC-RR-26, FC-RR-50). The company also provides R&D services including analytical testing, pilot facilities, and application engineering.
