Innovative carbon and graphite materials for rockets and missiles

Contact 0

In a world where extreme temperatures, mechanical loads, and reliability requirements define mission success, carbon and graphite solutions enable new levels of performance in rocket and missile systems.

SGL Carbon provides carbon and graphite materials specifically developed for use under the harshest conditions. They support demanding applications in the aerospace, security, and defense sectors, where materials must not only perform, but endure.

Rockets and missile propulsion and protection systems are subjected to severe mechanical, thermal, and chemical stresses. To meet these challenges, carbon-based materials offer a unique combination of properties such as ablative behavior for thermal protection, high thermal conductivity for efficient heat dissipation, and temperature and corrosion resistance for long-term durability in extreme environments. These capabilities make carbon and graphite key materials for critical mission components in the defense industry.

Our materials are used in a wide range of components, such as rocket nozzles, burning chambers, heat shields, insulations, sealings, and manufacturing tools.

SIGRABOND Carbon Composite Plates, Profiles and Fasteners

Plates, profiles, threaded rods, screws and nuts made of SIGRABOND are used to mounting or protecting furnaces insulations and other furnace components.

They provide high tenacity at very low weight and are therefore perfect to protect your insulation from corrosion and damage.

SIGRATHERM^® Rigid Felt Insulation

Insulation material made of carbon fibers

Our SIGRATHERM rigid felts fulfill your special requirements. This starts with standard plates and blocks and proceeds to highly specialized products like SIGRATHERM HIP cylinders for high pressure sintering furnaces. We also develop your special material recipe with you.

Dimensions for single piece cylinders: max. length 3,8 m by max. 1500 mm diameter
Plate sizes: 1524 x 1219 mm and 1500 x 1000 mm
Block sizes: 1524 x 1219 x 400 mm

Rayon carbon fabric for thermal protection systems

Carbon rayon fabric characterized by its extreme temperature resistance and high-quality is used to produce carbon cloth polymer composites like phenolic resin-based materials. The composites are key for protecting structural components of rockets, space shuttles, and satellites from heat – functioning as ablative or sacrificial materials. They are critical to their safe operation.
