PRODUCTION OF CARBON/CARBON COMPOSITE MATERIAL

摘要

PURPOSE:To provide production method for obtaining carbon/carbon composite material free from crack and peeling simple in impregnation process. CONSTITUTION:A pitch based carbon fiber precursor having 1000-1000000 ratio of length/diameter and carbonaceous pitch are packed into a vacuum vessel and heated under reduced pressure to give a impregnate, which is then subjected to carbonization treatment under press or under pressure to produce the objective carbon/carbon composite material.
