Abstract: Based on the carbon fiber reinforced paper type friction material prepared by our laboratory, the influences of curing pressure on the friction materials, including porosity, dynamic friction coefficient, static/dynamic friction coefficient ratio and friction torque, were studied. The results show that the porosities of samples decrease with the increasing curing pressure; dynamic friction coefficients of samples decrease at different curing pressures with increasing the braking pressure, while the influence on the static/dynamic coefficient ratios is somewhat complex: with increasing the braking pressure, the static/dynamic coefficient ratios of the samples cured at relatively lower pressures tend to rise slightly, as the static/dynamic coefficient ratios of the samples cured at higher pressures tend to decline; there arises a slight cock at the end of the friction torques gradually. 3.4MPa is the proper curing pressure for the carbon fiber reinforced paper based friction material with fixed component, taking all of the influences shown above into account.
