Abstract

Cesic -- a trademark of ECM for carbon-fiber reinforced silicon carbide -- allows relatively quick and cheap manufacturing of components with good repeatability and reproducibility due to the implemented product assurance (PA) system. Through a joining process and our development of optical surfaces, Cesic allows for a direct up-scaling of structures and optical surfaces to large-size applications and systems. The size of the structures and mirrors that can be manufactured is limited only by the scale of the available furnaces facilities, the largest of which currently is 2.4 m in diameter. Under ESA contract ECM performed a measurement program to get reliable material properties data on Cesic for space and other future programs.
