ULTRA-LIGHTWEIGHT C/SIC MIRRORS AND STRUCTURES
Description
C/SIC Structures obtains its outstanding properties from the combination of carbon fiber with a silicon carbide (SiC) matrix. This leads to a composite material (C/SiC) with high hardness but also good fracture toughness.

Work Application
C/SIC Ceramic MF is particularly suitable for applications requiring high wear resistance, high mechanical strength and low weight. In addition to its high thermal conductivity, this material exhibits the typical brittle fracture behavior of a ceramic. For this purpose, C/SIC Ceramic was used as material for the instrument panels of the satellite.
Ductile materials are obtained by incorporating short carbon fibers into a ceramic matrix. This material is characterized by a pseudo-plastic behavior under mechanical stress. The amount of carbon fibers in the ceramic matrix allows tailoring a wide range of mechanical and physical properties to your requirements. C/SIC Ceramic SF is established in the automotive industry for serial-produced C/SiC brake disks.
C/SIC Ceramic LF is especially suitable for applications under the highest mechanical stress. By incorporating long or continuous carbon fibers into a ceramic matrix, materials which are more dominated by the fiber properties than by the properties of the ceramic matrix are obtained. This material is characterized by a low density with high elongation at break and high strength. Today, /SIC Ceramic LF is mainly used in the field of ceramic C/SiC clutch disks for high-performance vehicles.
Composite materials with ceramic matrix
Ceramic matrix composite materials are a solution to the limit that advanced ceramics present for structural applications. Carbon-ceramic brake discs are made of a ceramic matrix (usually silicon carbide), and of high-strength carbon or silicon carbide fibers.
