Abstract

Graphite/phenolic-based composite was fabricated through hot compression molding followed by heat-treatment process. The length, density, flexural strength and electrical conductivity of composite are analyzed to determine the influences of heating rate on the physical, mechanical and electrical properties of composite. It is found that the shrinking in length of composites heat-treated at low heating rate was larger than that at high heating rate, however the changes in density showed the opposite trend. The flexural strength, hardness and electrical conductivity of the heat-treated composites generally decreased with increasing heating rate. Comprehensive comparison of mechanical, electrical performance and manufacturing cost at different heating rates obtained from the above work, the optimum heating rate is 2 /min. The corresponding values of flexural strength, hardness and electrical conductivity of composite are 69 Mpa, 55 and 6.44 103 S/m, respectively.
