Zusammenfassung: | PURPOSE: A method for fabricating a needle-punched carbon composite is provided to prevent delamination or crack of layers and to save production cost. CONSTITUTION: A method for fabricating a needle-punched carbon composite comprises: a step of preparing a fiber layer of a predetermined thickness using a heat resistant fiber(S101); a step of laminating the prepared fiber layers and needle-punching while compressing the fiber layers to tight the fiber layers(S102); a step of performing thermal treatment of the fiber reinforcing material(S103); and a step of filling the fiber reinforcing material with a carbon ingredient(S104). The heat resistant fiber is an oxidized-polyacrylonitrile fiber. The fiber layer has a form of a woven fabric, a non-woven fabric, a knitted fabric, a multiaxial warp knitted fabric, a unidirectional fabric, or a web.
