Abstract

Synthesis and properties of epoxy resin/graphite composites via in situ condensation polymerization of monomers in the presence of graphite particles were investigated. The results showed graphite particles were well dispersed in the epoxy resin matrix. Shore hardness and bending strength varied with the amount of graphite, and they were all improved greatly by an optimal content of 17.44 % (mass fraction). The bending strength was 22.4MPa and Shore hardness was 9.8 HD. A plastic deformation can be seen in the composite with the range of strain 0.6-0.8%. The fitted yield strength is about 20MPa.
