Influence of curing pressure on the friction performance of a kind of paper based friction material

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.
