Development and use of an apparatus for tribological evaluation of ceramic-based brake materials

Friction behavior of sintered metallic brake pads on a C/C–SiC composite brake disc

“…Based on the high temperature gradient beneath the surface of the pad and taking into account the nature and structure of the C/C-SiC disc, we believe that the actual contact temperature could be as high as 700 • C or more. 13,14 The AES analyses on the brake-pad friction layer indicated a two-layer oxide structure. The concentration-profile diagrams of samples M35 and G15 (Fig.…”

Tribological behaviour of C/C–SiC composites—A review

“…Tribological properties depend upon the microstructure and properties of the preform [8,51]. The effect of graphitization on microstructure and mechanical properties of C/C-SiC composites is investigated by many researchers, but its effect on tribological properties of C/C-SiC composites has not been investigated much [52][53][54][55][56]. Figure 12 shows the curves of coefficient of friction of samples ((a) without graphitization and (b) with graphitization) as a function of braking time.…”

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

“…These elements are either forecast or are already being used in high-speed trains: TVG (France), Talent (Germany), Pendolino (Italy), APT (Britain), AVE (Spain), HSR-350x (Korea), Shinkansen (Japan), and in various other countries. The mass of a single steel braking disk is more than 100 kg, and the mass is halved by using composite materials with ceramic matrices, which reduces the total weight of a high-speed train by more than 5 ton [25].…”
