ABSTRACT:
Binder-impregnated carbon fiber rovings and the like, which are sticky and difficult to handle, are stacked to form modules that are packed in resinous bags under vacuum, and are then shaped to desired dimensions and densities without employing conventional molds, but simply by placing them in the confines of jigs or ruler frames and then releasing them from vacuum and expanding them to the desired dimensions. They are thereafter subjected to heat treatments to provide high temperature resistant carbon fiber-reinforced carbon or graphite modules which work, for example, as thermal insulation and refractory walls in high temperature heating furnaces.
