SGL Group: Ceramic Component on Its Way to Jupiter

• Optical bench made for NASA’s Juno mission at the Hannover Fair
• Exhibited in Hall 2 on the joint booth with MST Aerospace (Booth D 56)

Meitingen/Hannover, April 26, 2012. At the Hannover Fair from April 23 – 27, 2012, SGL Group - The Carbon Company - is exhibiting a component made from the ceramic composite, SIGRASIC®, which is being used in NASA’s Juno mission. Mounted on a boom outside the spacecraft is this so-called optical bench which holds the magnetometer that will measure the magnetic field of the planet Jupiter.

For this mission, a nonmagnetic material was required that was lightweight and extremely strong at the same time to withstand the high thermal and mechanical stresses during the launch and the space flight itself, which will take over four years.

As a carbon fiber-reinforced silicon carbide (C/SiC), SIGRASIC has the optimum material properties. The combination of carbon fibers with a ceramic matrix gives the material high wear and fracture resistance plus the necessary stability to temperature extremes and thermal shock, while also offering the key advantage of light weight.

SGL Group is a pioneer in this material class. A well-known application for C/SiC is the carbon-ceramic brake disk, which was fitted as standard for the first time on the Porsche GT2 and is now being used on other luxury and sports cars. On the basis of this expertise, the global Technology & Innovation (T&I) research team is working intensively in collaboration with partners to develop new applications and open up new markets.

In addition to the optical bench, which was produced together with SGL’s subsidiary, HITCO Carbon Compsites, Electrotech Machining (Long Beach, CA), and TQ Abra-sives (Santa Ana, CA), T&I is also exhibiting another result of successful collaboration in the form of serial applications for clutch systems in the motor sport sector. The system partner here is ZF Sachs Race Engineering.

Projects currently in progress are exploiting other properties of SIGRASIC that were utilized in the optical bench, such as its minimal thermal expansion and suitability for shaping into complex geometric designs.
