By substituting 10 wt% of conventional graphite particles, pitch coke particles with fine mosaics demonstrate superior performance in enhancing the braking properties of copper metal matrix composites (CMMCs) operating at various conditions. When mated with C/C-SiC, the coefficient of friction increases by 18.6 % at low speeds and 38.8 % at high braking speeds, along with a significant enhancement in wear resistance across various counterparts. This improvement is attributed to the incorporation of pitch coke with fine mosaics and superior mechanical properties, which not only imparts high the...
