Abstract
A method of manufacturing a three dimension preform having high thermal conductivity includes: a first step of manufacturing a unidirectional carbon fabric from a heat resistant fiber; a second step of putting the unidirectional carbon fabric into an aqueous solution with carbon nanomaterials contained in a vessel; a third step of taking the unidirectional carbon fabric out of the vessel and then drying the unidirectional carbon fabric; a fourth step of repeating the second step and the third step; a fifth step of stacking the unidirectional carbon fabrics with web carbon fabrics, which are made of a heat resistant fiber, inserted between the unidirectional carbon fabrics; and a sixth step of punching the stacked unidirectional carbon fabrics and the web carbon fabrics with a needle.
