Abstract
In place of mechanical complicated pressure means which apply a pressure upon binder impregnated carbon fibers when they are heated to be a compounded compact of a desired shape, thermo-resistant fibers having a negative coefficient of linear expansion and wound up directly or indirectly over the carbon fibers, are employed so that they tightly fasten the carbon fibers under a pressure on account of their contraction by heat, whereby the shaping and heating of the carbon fibers can readily be achieved and controlled.
