Description
본 발명은 탄소복합재 프리폼 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a carbon composite preform.
탄소복합재(Carbon-Carbon Composite)는 경량이며, 고온에서 우수한 기계적 강도를 유지하며, 열·화학적 침식 환경에서 우수한 내식성, 내열성을 가지며, 우수한 마찰·마모 특성을 가진다.Carbon-Carbon Composite is lightweight, maintains excellent mechanical strength at high temperatures, has excellent corrosion resistance and heat resistance in thermal and chemical erosion environments, and has excellent friction and abrasion characteristics.
이러한 특성으로 인해, 탄소복합재는 항공기와 육상용 운송수단의 브레이크 디스크, 로켓 노즐, 고온 내열 지그 등에 사용된다.Due to these characteristics, carbon composites are used in brake discs, rocket nozzles, and high-temperature heat-resistant jigs of aircraft and land vehicles.
탄소복합재의 제조방법은 탄소복합재 프리폼(Preform)을 제조하는 공정과, 탄소복합재 프리폼을 밀도화하는 공정으로 크게 나눌 수 있다.The carbon composite material manufacturing method can be roughly divided into a process of manufacturing a carbon composite material preform and a process of densifying the carbon composite material preform.
탄소복합재 프리폼은 서로 적층된 탄소직물 시트들과 그 사이사이에 삽입된 탄소섬유 웹이 적층되고, 적층방향(수직방향)으로 니들펀칭(Needle Punching)되어 만들어진다.The carbon composite preform is made by stacking carbon fabric sheets stacked on top of each other and a carbon fiber web inserted therebetween, and needle punching in the stacking direction (vertical direction).
니들펀칭시, 미늘(Barb)들이 형성되어 있는 니들(needle)들이 탄소섬유 웹을 구성하는 짧은 탄소섬유를 적층방향(수직방향)으로 끌고 내려가, 탄소직물 시트들을 층간 결합시킨다.During needle punching, needles with barbs are formed to drag the short carbon fibers constituting the carbon fiber web in the lamination direction (vertical direction), thereby bonding the carbon fabric sheets between layers.
그러나, 탄소섬유 웹을 구성하는 짧은 탄소섬유가 수직방향으로 배열되어, 탄소직물 시트들을 층간 결합시킨 것만으로는, 탄소직물 시트들의 층간 결합력이 충분치 못하다.However, only short carbon fibers constituting the carbon fiber web are arranged in a vertical direction and the carbon fabric sheets are interlayer bonded, but the interlayer bonding force of the carbon fabric sheets is not sufficient.
또한, 미늘들이 형성되어 있는 니들들이 탄소직물 시트들을 반복적으로 관통하면서, 탄소직물 시트를 손상시킨다.In addition, the needles on which the barbs are formed repeatedly penetrate the carbon fabric sheets, thereby damaging the carbon fabric sheets.
이로 인해, 탄소복합재 프리폼의 내구성이 떨어지고, 결국 탄소복합재의 품질 저하로 이어진다.For this reason, the durability of the carbon composite preform is deteriorated, which leads to deterioration of the quality of the carbon composite material.
본 발명의 목적은, 상술한 문제점을 해결할 수 있는 탄소복합재 프리폼 제조방법을 제공하는 데 있다.An object of the present invention is to provide a method for manufacturing a carbon composite preform capable of solving the above-described problems.
상기 목적을 달성하기 위한 탄소복합재 프리폼 제조방법은, A carbon composite preform manufacturing method for achieving the above object,
탄소직물 시트를 복수 개 적층하여 탄소직물 적층체를 형성하는 제1단계; 및A first step of stacking a plurality of carbon fabric sheets to form a carbon fabric laminate; and

또한, 상기 목적을 달성하기 위한 탄소복합재 프리폼 제조방법은, In addition, the carbon composite material preform manufacturing method for achieving the above object,
탄소직물 시트를 복수 개 적층하여 탄소직물 적층체를 형성하는 제1단계; 및A first step of stacking a plurality of carbon fabric sheets to form a carbon fabric laminate; and
상기 탄소직물 적층체를 꼬인 탄소섬유로 이루어진 바느질 섬유로 바느질하여 적층된 상기 탄소직물 시트들을 서로 결속시키는 제2단계를 포함하는 것을 특징으로 한다.and a second step of binding the laminated carbon fabric sheets to each other by sewing the carbon fabric laminate with sewing fibers made of twisted carbon fibers.
또한, 상기 목적을 달성하기 위한 탄소복합재 프리폼 제조방법은, In addition, the carbon composite material preform manufacturing method for achieving the above object,
탄소직물 시트를 복수 개 적층하여 탄소직물 적층체를 형성하는 제1단계; 및A first step of stacking a plurality of carbon fabric sheets to form a carbon fabric laminate; and
상기 탄소직물 적층체를 꼬인 또는 꼬이지 않은 탄소섬유의 외면을 고분자 섬유로 감싸서 이루어진 바느질 섬유로 바느질하여 적층된 상기 탄소직물 시트들을 서로 결속시키는 제2단계를 포함하는 것을 특징으로 한다.and a second step of binding the laminated carbon fabric sheets to each other by sewing the carbon fabric laminate with a sewing fiber made by wrapping the outer surface of the twisted or untwisted carbon fiber with a polymer fiber.
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. The present invention prepares a carbon composite preform by laminating a plurality of carbon fabric sheets to form a carbon fabric laminate, then stitching the carbon fabric laminate with sewing fibers to bind the stacked carbon fabric sheets to each other. Therefore, instead of simply arranging the short carbon fibers constituting the carbon fiber web in a vertical direction as in the conventional needle punching method and bonding the carbon fabric sheets between layers, the stacked carbon fabric sheets are tied with a sewing thread by sewing, so the carbon fabric The bond between the sheets is strengthened. For this reason, the durability of the carbon composite preform is improved, which leads to improvement in the quality of the carbon composite material.
본 발명은 탄소섬유를 바느질 하여 탄소직물 시트들을 층간 결합시키므로, 미늘(barb)들이 형성되어 있는 니들들을 탄소직물 시트들을 반복적으로 관통시킬 필요가 없어, 탄소직물 시트의 손상이 줄어든다.Since the present invention stitches carbon fibers to bond the carbon fabric sheets between layers, there is no need to repeatedly pierce the carbon fabric sheets with needles having barbs formed therein, thereby reducing damage to the carbon fabric sheets.
본 발명은 판재형 뿐만 아니라, U-Shape, I-Shape 형태 등 다양한 형태의 탄소복합재 프리폼을, 탄소직물 시트를 바느질로 하여 만들 수 있다.According to the present invention, carbon composite preforms of various types such as U-Shape, I-Shape, etc., as well as plate type, can be made by sewing carbon fabric sheets.
본 발명은 꼬인 탄소섬유를 바느질 섬유로 사용하여, 바느질 섬유가 탄소직물 시트를 관통하면서 발생하는 마찰력을 꼬인 방향으로 분산시킨다. 이로 인해, 표면 마찰에 약한 탄소섬유로 구성된 바느질 섬유가 손상되는 것을 줄일 수 있다. 또한, 탄소섬유에 꼬임을 줌으로 인해 바느질 섬유의 강도가 보강된다.The present invention uses twisted carbon fibers as sewing fibers to disperse frictional force generated while the sewing fibers penetrate the carbon fabric sheet in the twisted direction. Due to this, it is possible to reduce the damage to the sewing fibers composed of carbon fibers weak to surface friction. In addition, by giving twist to the carbon fiber, the strength of the sewing fiber is reinforced.
본 발명은 꼬인 탄소섬유를 고분자 섬유로 감싼 바느질 섬유를 사용하여, 바느질 섬유가 탄소직물 시트를 관통할 때, 탄소섬유가 직접적으로 탄소직물 시트와 마찰되는 것을 막는다. 이로 인해, 표면 마찰에 약한 탄소섬유로 구성된 바느질 섬유가 손상되는 것을 막을 수 있다. 또한, 고분자 섬유로 인해, 바느질 섬유의 강도가 더 보강된다.The present invention prevents the carbon fiber from directly rubbing with the carbon fabric sheet when the sewing fiber penetrates the carbon fabric sheet by using a sewing fiber wrapped with a polymer fiber in a twisted carbon fiber. Due to this, it is possible to prevent damage to the sewing fibers composed of carbon fibers that are weak in surface friction. Also, due to the polymer fiber, the strength of the sewing fiber is further reinforced.
