摘要：
A process for the preparation of high-performance grade carbon fibers, which comprises attaching a fine powder of at least one member selected from oxides and carbides of silicon, aluminum, titanium, and boron to a precursor fiber bundle of as spun pitch fibers, subjecting the fiber bundle to an infusibilization treatment, and subjecting the fiber bundle to a carbonization treatment.
