Description
본 발명은 본 발명인이 선출원한 제 20-2002-25794호 '매듭성형 권선기가 형성된 필라멘트 와인딩 장치'를 이용한 필라멘트 와인드 원심(遠心) 제조방법 및 그 장치에 관한 것으로, 더욱 상세하게는 멘드릴에 와인딩되는 보강섬유에 수지함침조를 대신하는 분사장치로 고분자수지를 분사하고, 분사된 멘드릴은 고속 회전시키는 회전장치에 장착함으로써, 회전장치에 의한 원심력으로 수지함침시 발생하는 기포생성을 방지하고, 보강섬유 사이에 수지를 고르게 분포시켜 제품의 품질을 향상시킬 뿐만 아니라, 불균일한 외표면을 2차 가공하는데 소요되는 비용을 저하시키는 필라멘트 와인드 원심(遠心) 제조방법 및 그 장치에 관한 것이다. The present invention relates to a method for manufacturing a filament winding centrifugal apparatus using the 'filament winding device formed with a knot-shaped winding machine' and the device, and more particularly winding to the mandrel The polymer resin is sprayed on the reinforcing fiber to be used as an injection device replacing the resin impregnation tank, and the injected mandrel is mounted on a rotating device to rotate at a high speed, thereby preventing bubbles generated during resin impregnation by centrifugal force by the rotating device. The present invention relates to a filament winding centrifugal manufacturing method and apparatus for not only improving the quality of a product by uniformly distributing resin between reinforcing fibers, but also reducing the cost of secondary processing of an uneven outer surface.
일반적으로 필라멘트 와인딩 공법(Filament Winding Process)은 섬유공급장치를 통해 수지함침한 보강섬유를 멘드릴에 다수회 와인딩하여 가열경화시킴으로서, 파이프나 압력용기 등의 실리더형 구조물을 제작하는 것이다. 하지만 상기와 같은 필라멘트 와인딩 공법은 멘드릴이나 회전암의 회전각이 제한됨으로 멘드릴축 방향과 일치되도록 보강섬유를 배열시킬 수 없으며, 이로 인하여 길이가 단면에 비해 아주 긴 제품을 생산할 경우 다량의 보강섬유가 소모될 뿐만 아니라, 생산에 따른 시간도 많이 소모되는 등의 문제점이 발생하였다.In general, the filament winding process (Filament Winding Process) by winding the resin impregnated reinforcing fibers in the mendrel multiple times through a fiber supply to heat-harden, to produce a cylinder-type structure such as pipes or pressure vessels. However, the filament winding method as described above does not arrange the reinforcing fibers to match the direction of the mandrel axis because the rotation angle of the mandrel or the rotary arm is limited. As a result, a large amount of reinforcement is produced when producing a product having a very long length compared to the cross section. Not only the fiber is consumed, but also a lot of time due to the production, such as a problem occurred.
따라서 근래에 본 발명인이 보강섬유를 멘드릴축 방향으로 배열하여 단면에 비해 길이간 긴 제품을 와인딩할 수 있는 매듭성형 권선기가 형성된 필라멘트 와인딩 장치(선출원 제 20-2002-25794호)를 고안한 것이 있으나, 이는 수지함침시 발생하는 기포가 제품에 내재됨으로써 제품의 기계적 성질이 저하될 뿐만 아니라, 표면이 고르지 못하고, 2차 가공이 필수적어서 생산비용의 상승을 유발하고 있는 실정이다.Therefore, the inventors of the present invention devised a filament winding device (former application No. 20-2002-25794) having a knotted winding machine capable of winding a product having a length longer than a cross-section by arranging the reinforcing fibers in the mendrel axis direction. However, this is a situation in which the bubbles generated during the resin impregnation not only lowers the mechanical properties of the product, but also the surface is uneven, the secondary processing is necessary to increase the production cost.
본 발명의 목적은 종래의 이와같은 문제점을 해소하고자 한 데 있는 것으로, 수지분사단계(A1), 저속회전단계(A2), 멘드릴인출단계(A3), 수지주입단계(A4), 고속회전단계(A5), 공기주입단계(A6)를 거쳐 단면에 비해 길이가 긴 제품을 제조함으로써, 보강섬유에 발생하는 기포생성을 원천적으로 방지하여 외표면이 매끄럽고 균일한 고품질의 제품을 생산할 수 있을 뿐만 아니라, 외표면 성형을 위한 별도의 공정이 필요없어 생산비용을 절감하고, 생산공정은 최소화할 수 있는 필라멘트 와인드 원심(遠心) 제조방법 및 그 장치를 제공코자 하는데 그 목적이 있다. The object of the present invention is to solve such problems in the prior art, resin injection step (A1), low-speed rotation step (A2), mendrel take-out step (A3), resin injection step (A4), high speed rotation step (A5) By manufacturing the product having a longer length than the cross-section through the air injection step (A6), it is possible to produce a high-quality product with a smooth and uniform outer surface by preventing the generation of bubbles generated in the reinforcing fiber. The purpose of the present invention is to provide a filament winding centrifugal manufacturing method and apparatus for reducing the production cost and minimizing the production process since no separate process is required for external surface forming.
