A method for forming a composite of exfoliated graphite dispersed in a polymeric resin matrix which comprises; (a) forming a suspension comprising intercalated unexfoliated graphite flakes in a liquid polymeric thermoset resin matrix, wherein the liquid resin cures at a temperature above the graphite exfoliation onset temperature, (b) heating to a temperature above the graphite exfoliation onset temperature to exfoliate the graphite flakes and initiate solidification by curing of liquid thermoset resin, and maintaining a temperature to fully solidify the thermoset resin to form a solid composite comprising graphite flakes with an expanded exfoliated structure dispersed in a solid polymer matrix.
