본 발명은 필라멘트 와인딩 장치의 수지함침 장치에 관한 것으로서, 보다 상 세하게는 고분자 복합재료의 필라멘트 와인딩 성형에 사용되는 수지함침장치에 초음파를 사용하여 수지함침을 용이하게 한 것이다.The present invention relates to a resin impregnation apparatus of a filament winding apparatus, and more particularly, to facilitate resin impregnation by using ultrasonic waves in a resin impregnation apparatus used for filament winding molding of a polymer composite material.

일반적으로, 필라멘트 와인딩 성형에서 수지함침장치는 섬유스풀에서 공급되는 섬유로빙에 수지를 적시는 장치로서 수지함침장치에서 수지가 적셔진 섬유로빙은 와인딩 스핀들의 맨드렐에 감기게 된다. 이 때 수지의 점도, 섬유로빙의 장력, 와인딩 속도, 함침롤러의 압력 등에 의하여 섬유로빙에 남아있는 수지의 양이 달라지게 되고 이는 제품의 품질을 좌우하는 요인이 된다. In general, in the filament winding molding, the resin impregnation device wets the resin in the fiber roving supplied from the fiber spool, and the resin fiber impregnation in the resin impregnation device is wound on the mandrel of the winding spindle. At this time, the amount of resin remaining in the fiber roving depends on the viscosity of the resin, the tension of the fiber roving, the winding speed, and the pressure of the impregnation roller, which is a factor in determining the quality of the product.

기존의 수지함침장치는 수지함침장치에 설치된 롤러와 같은 기구의 기계적인 마찰을 이용하여 섬유로빙에 수지를 적시는 방법을 주로 사용하는데, 수지가 묻어 있는 실린더 형태의 롤러 위를 보강섬유가 지나가게 하여 섬유로빙에 수지를 적시거나 수지가 채워진 용기 내부에 장착된 바(bar) 형태의 롤러 사이로 보강섬유가 지나가게 하여 섬유로빙에 수지를 적시는 방법이 사용되고 있다. 일반적으로 전자를 롤러(roller) 방식이라 하고, 후자를 K(deep) 방식이라 한다.Conventional resin impregnation device is mainly used to wet resin in fiber roving by using mechanical friction of mechanism such as roller installed in resin impregnation device. To wet the resin in the fiber roving or to pass the reinforcing fibers between the roller (bar) roller mounted inside the container filled with resin to wet the resin in the fiber roving. In general, the former is called a roller method, and the latter is called a K (deep) method.

필라멘트 와인딩 공법으로 제품을 성형할 때, 생산성을 향상시키기 위해서는 와인딩 속도 증가가 불가피하다. 하지만 와인딩 속도가 증가됨에 따라 강화 섬유가 멘드렐에 감기는 속도가 빨라지게 되고, 이로 인해 수지함침장치를 지나는 섬유로빙에 수지가 균일하게 적셔지지 않아 제품 품질이 떨어지게 되는 문제가 발생하게 된다. 특히 롤러방식의 경우 롤러 위로 묻어나오는 수지의 양을 조절함으로써 섬유로빙에 함침되는 수지의 함침량을 조절하게 되는데, 와인딩 속도가 증가될수록 수지 함침량이 일정하지 않게 되는 문제가 있다. 또한 필라멘트 와인딩된 제품의 수 지의 함침량을 최종 제품의 무게비로서 분석하게 되는데, 이는 수지가 섬유로빙 내부까지 균일하게 함침되었다는 가정하에 제품의 수지 함침량을 평가한다. 하지만 고속 와인딩 된 제품의 경우 수지가 섬유로빙 내부까지 균일하게 함침되지 않고, 섬유로빙의 표면에 만 묻어있게 되어 제품의 성능이 저하되는 문제가 발생할 수 있다. 따라서 필라멘트 와인딩 제품의 품질 및 생산성을 향상시키기기 위해서는 섬유로빙에 수지를 균일하게 함침시킬 수 있는 수지함침장치가 반드시 필요하다.When forming a product by the filament winding method, it is inevitable to increase the winding speed in order to improve productivity. However, as the winding speed is increased, the reinforcing fiber is fastened to the mandrel, which causes a problem that the resin quality is not uniformly soaked in the fiber roving passing through the resin impregnation device, thereby degrading product quality. In particular, the roller method is to control the amount of resin impregnated in the fiber roving by adjusting the amount of resin buried above the roller, there is a problem that the resin impregnation amount is not constant as the winding speed increases. In addition, the impregnation amount of the resin of the filament wound product is analyzed as the weight ratio of the final product, which evaluates the resin impregnation amount of the product under the assumption that the resin is uniformly impregnated to the inside of the fiber roving. However, in the case of a high-speed winding product, the resin is not uniformly impregnated to the inside of the fiber roving, and only a surface of the fiber roving may cause a problem of deterioration of the performance of the product. Therefore, in order to improve the quality and productivity of the filament winding product, a resin impregnation apparatus capable of impregnating a resin in the fiber roving is necessary.

상기와 같은 문제점을 해결하기 위해 본 발명의 수지함침장치는 초음파로 보강섬유 표면과 수지를 가진시켜 수지가 섬유로빙 내부에 균일하게 함침되도록 함으로써 품질이 우수한 필라멘트 와인딩 제품을 생산할 수 있는 필라멘트 와인딩용 수지함침장치를 제공하는데 그 목적이 있다.In order to solve the above problems, the resin impregnating device of the present invention has a filament winding resin which can produce a high quality filament winding product by allowing the resin to be uniformly impregnated in the fiber roving by having the reinforcing fiber surface and the resin with ultrasonic waves.

Figure 1 is a roller method in which the ultrasonic generator 4 is inserted into the roller 2 of the resin impregnation apparatus and ultrasonic waves are radiated from the roller surface so that the resin surface is covered with the ultrasonic fiber when the reinforcing fiber 7 passes. By having the furnace reinforcing fiber surface and the resin, the resin can be uniformly impregnated inside the fiber roving. The ultrasonic wave generator 4 of the ultrasonic resin impregnation device can maintain a uniform resin impregnation rate by changing the frequency using the ultrasonic control device 10 according to the viscosity of the resin and the winding speed.
