Carbon/carbon (C/C) composites with smooth laminar texture pyrocarbon (SL), rough laminar texture pyrocarbon (RL) and RL pyrocarbon adding particle resin carbon were prepared, respectively. The open porosities of the composites were measured by Archimedes principle, and their mechanical and thermophysical properties were tested. The friction properties of the braking disc prepared from the three types C/C composites were tested at stimulating airplane braking conditions. The friction coefficient of the SL C/C composites with is 0.26 under normal landing condition. For the RL C/C composites with open porosity of 13%, the friction coefficients are 0.35, 0.24, 0.29 under normal landing (NL), rejected take-off (RTO), damp landing (DL) conditions, respectively. The friction coefficients of C/C composites with RL pyrocarbon adding particle resin carbon (open porosity is 8%) are 0.36, 0.31, 0.36 under NL, RTO, DL conditions, respectively. The results show that the RL pyrocarbon increases the friction coefficients of the C/C. The addition of particle resin carbon in the C/C increases the braking efficiency of C/C composites under high energy landing. Low porosity C/C has better braking efficiency under DL condition.
