Ceramic Composites for Automotive Friction Devices

Braking friction materials based on fiber-reinforced composites with carbon and ceramic matrices

“…Moreover, the fibers are usually protected by appropriate coating, e.g., a double interphase coating of BN/SiC type, which acts as a protective barrier [11]. The frictional CCM materials made in that way may have various structures, which are dependent largely on the method of fitting in the carbon component: layerwise stacking of carbon cloth or unidirectional layers, or chaotic reinforcement with fibers of various lengths, e.g., a mixture of fibers with mean lengths of 3 and 50 mm [12], and also very short broken fibers of length 0.70 mm [13].…”
