METHOD FOR MANUFACTURING CARBON-CARBON COMPOSITE PREFORM
The present invention relates to a method for manufacturing a carbon-carbon composite preform, which stacks a plurality of carbon fabric sheets to form a carbon fabric laminate and sews the carbon fabric laminate with sewing fibers to bind the stacked carbon fabric sheets to each other, thereby manufacturing a carbon-carbon composite preform. According to the present invention, instead of simply arranging short carbon fibers forming a carbon fiber web in a vertical direction and bonding carbon fabric sheets between layers as in the conventional needle punching method, stacked carbon fabric sheets are stitched together with a sewing thread, so that a binding force between the carbon fabric sheets is increased. Accordingly, durability of the carbon-carbon composite preform is increased, and thus quality of carbon-carbon composites is improved.
본 발명은 탄소직물 시트를 복수 개 적층하여 탄소직물 적층체를 형성한 후 탄소직물 적층체를 바느질 섬유로 바느질하여 적층된 탄소직물 시트들을 서로 결속시켜 탄소복합재 프리폼을 제조한다. 따라서, 종래의 니들 펀칭 공법에서처럼 탄소섬유 웹을 구성하는 짧은 탄소섬유를 단지 수직방향으로 배열하여 탄소직물 시트들을 층간 결합시키는 것이 아닌, 적층된 탄소직물 시트들을 바느질에 의해 바느질 실로 묶어주므로, 탄소직물 시트 간 결속력이 강화된다. 이로 인해, 탄소복합재 프리폼의 내구성이 향상되고, 결국 탄소복합재 품질 향상으로 이어진다.
