Abstract:
A method of forming a high thermally conductive and high strength article, comprising the steps of:providing a polymer base matrix of, by volume, between approximately 30 and 70 percent; providing a first filler of high modulus PITCH-based carbon material, by volume, between approximately 15 and 47 percent; the first filler having an aspect ratio of at least 10:1; providing a second filler of polyacrylonitrile based carbon material, by volume, between approximately 10 and 35 percent, the second filler having an aspect ratio of at least 10:1; mixing the polymer base matrix, the first filer and the second filler together into a molding composition; and net-shape injection molding the molding composition into an article having a thermal conductivity of at least 4 W/mÂ° K and a tensile strength of at least 15 ksi.
