Improvement of high-temperature resistance on carbon fiber felt/portland cement composite friction material by Al2O3 sol–gel coating

The extrusion impregnation method is used to prepare carbon fiber felt/portland cement (CFF/PC) composite materials. The samples are placed into muffle furnace for ablation, but carbon fiber is oxidized at around 450 °C. To improve the oxidation resistance of carbon fiber, Al 2 O 3 sol–gel (AS) is p...
