BJS Ceramics GmbH

BJS Ceramics is a small company and start-up in the field of ceramic fibers. We develop and produce SiC fibers based on our own patented technology, which is unique in the world and the only technology that allows the programming of functionalities in SiC fibers. This is important for the best performance in the application, the so-called CMCs (i.e. SiC fiber-reinforced SiC components). Our SiC fibers show superior properties for low observability and mechanical strength in CMCs compared to competing fibers from overseas. We have a purely EU-based value chain and are therefore only subject to EU and German export control laws. We guarantee the sovereignty of Germany and Europe for these critical high-temperature materials in applications such as aircraft engines, rocket engines, low-observability, components in nuclear applications (fission/fusion).

Silafil - functional SiC fibers for military applications

BJS Ceramics develops and produces silicon carbide (SiC) fibers as the only company in the EU. We have a purely EU-based value chain and are therefore only subject to the export control laws of the EU and Germany. Our fibers are used in "LO applications", among others, but also as reinforcing fibers in ceramic composite materials for engine components, rocket propulsion systems, space vehicles, etc.
