Press Release BJS Composites
Gersthofen, Germany, November 9, 2026
BJS Composites GmbH has delivered components for an application in the nuclear industry for the first time. This delivery marks an important milestone for the company as it expands into another strategic application area for its ceramic matrix composite materials.
Under its Keraman® brand, BJS Composites develops and manufactures customized Ceramic Matrix Composite (CMC) components. Its portfolio includes material development, prototyping and the production of both simple and highly complex 3D ceramic composite components, as well as various machining and joining technologies. BJS targets a range of application areas, including advanced energy applications and reactor technologies.
The first delivery of components for a Small Modular Reactor (SMR) based on a high-temperature reactor concept represents a significant step for BJS, advancing from the development and cooperation stage toward a tangible industrial application.
“With this first delivery, we have reached an important milestone. It demonstrates that our Keraman® technology is not only attractive for established high-temperature applications, but can also contribute to future applications in nuclear technology. Particularly in demanding environments, the unique properties of silicon carbide-based ceramic matrix composites can open up new technological opportunities,” says Dr. Werner Humbs, Managing Director of BJS Composites GmbH.
BJS technology is based on an integrated value chain extending from preceramic polymers and silicon carbide fibers to finished ceramic matrix composite components. BJS already targets applications in aerospace, space, defense, pump technology and advanced energy technologies with its materials. The company’s strategy explicitly includes fission, advanced reactors and fusion as target markets.
Silicon carbide-based materials are particularly attractive for applications involving demanding thermal, chemical and radiation environments. Among the key properties of its SiC-based composite components, BJS highlights high-temperature resistance, thermal-shock resistance, chemical resistance and radiation tolerance.
“For us, entering the nuclear market represents more than a single order. It is part of our strategy to deploy our advanced ceramic materials in applications where conventional materials reach their limits. This first delivery therefore provides an
important starting point for the further expansion of this business area,” adds Jutta Schull, Executive Partner and Co-Founder.
With this delivery, BJS is further expanding its activities in the energy sector. In addition to conventional fission reactors, the company considers Advanced Nuclear Reactors and fusion reactors to be important long-term application areas for its material technology. BJS has already initiated its first collaborations in these fields.
