A method of making carbon-carbon pistons and a limited variety of other products also requiring light weight, high strength and high thermal conductivity, and the resulting piston, including the steps of feeding impregnated fibers from spools into a layered bundle of fibers, coating the fibers with a carbonaceous material to form a preform, sleeving the preform with a thermoplastic sleeve, extruding the coated preform, passing the preform through an oven while compacting the preform further, and cutting the preform into standard lengths as the preform exits the furnace and achieves a degree of cool down. The pistons are machined from the cut preforms with the piston axis parallel to the fibers and layers. The pistons include crown, skirt, and wrist pin bosses and the axis of the wrist pin bosses is perpendicular to the fibers and layers.
