1. A method of impregnating a matrix comprising:

  • impregnating said matrix with a high thermal conductivity material loaded resin, wherein high thermal conductivity materials of said resin comprise 5-60% by volume of said resin, to produce a resin impregnated matrix;

    after said impregnating, but prior to curing said resin impregnated matrix compressing said resin impregnated matrix by approximately 5-30%, wherein said compressing is effective to provide a network of said high thermal conductivity materials having reduced distances between said high thermal conductivity materials loaded in said resin; and

    curing said resin impregnated matrix to effectively lock a position of said network of said high thermal conductivity materials in place;

    wherein said high thermal conductivity materials comprise at least one of silica, alumina, magnesium oxide, silicon carbide, boron nitride, aluminum nitride, zinc oxide and diamonds and dendrimers of approximately 1-1000 nm in size, and wherein said high thermal conductivity materials have aspect ratios of 10-50.
