A technique for fabricating an improved electronic enclosure. The electronicenclosure is made of graphite fibers dispersed directionally (non-homogeneous) in an absolac/polycarbonate (ABS/PC) resin mix, of which the composition is molded to form the the plastic enclosure. The graphite concentration is highest along the interior surface of the enclosure to provide improved heat transfer, as well as adequate EMI/RFI shielding. However, the graphite concentration decrease along the thickness, wherein at the outer surface, the graphite concentration level is zero. The directional variation in the graphite loading allows high graphite loading at the interior surface of the enclosure, but retains lower loading at other regions along the thickness so that rigidity and impact resistance are retained for the enclosure.
