Automotive Ind.- Braking systems 8/10 • Ceramic composite brakes: C/SiC – High braking performance – Low weight (2.4 g/cm 3) – Low wear rate – Operating temperatures 1,400C° • First studied in 1990s, available in 2000s – Mercedes CL 55 AMG F1 Lim. However, many of the fundamental mechanical and thermal properties of SiC CMCs depend strongly on the fabrication process. Precursors. Ceramic composites may be produced by traditional ceramic fabrication methods including mixing the powdered matrix material with the reinforcing phase followed by processing at elevated temperature: hot pressing, sintering. ceramic-matrix composites (CMCs), by incorporating fibres in ceramic matrices, not only exploit their attractive high-temperature strength, but also reduce the propensity for catastrophic failure [1, 2]. They consist of ceramic fibers embedded in a ceramic matrix, the fiber/matrix bonding being controlled through weak enough interphase. Follow. Table of Contents.
