... It is expected that these different approaches to the synthesis of ultrafine carbon filaments from gaseous precursors will in due course yield filaments with the desired mechanical properties, in which case the emphasis will shift to matrix infiltration processes and the control of matrix-filament adhesion for optimizing composite properties. The long-term goal of General Motors Corporation, for example, is to commercialize the technology for producing carbon fibers at a cost competitive with that for glass fibers currently used in fiber-reinforced plastic automotive bodies.
