Abstract
A method for manufacturing carbon-carbon composites includes steps of producing a mat using carbon fiber, carbon fabric, carbon sheet, or staple fiber; laminating at least three layers of mats; producing a preform using the laminated mats with a needle punching method; performing a first thermal treatment process on the produced preform at a predetermined temperature; densifying the first-thermal-treated preform; performing a second thermal treatment process on the densified preform; forming a predetermined shape out of the second-thermal-treated preform; and performing an oxidation resistant treatment process of the shaped preform.
