그러나 차체를 구성하기 위한 용접공정이나 조립공정은 복잡하며 오랜 제작기간이 필요할 뿐만 아니라 차체를 구성하는 각 부분이 금속재질로 구성되어 있어 상당히 큰 자중을 갖는다는 문제가 있다. However, the welding process or assembly process for constructing the vehicle body is complicated and requires a long manufacturing period, and there is a problem that each part of the vehicle body is composed of metal material and has a considerably large weight.

자중을 줄이기 위한 방안으로 차체의 재질을 알루미늄으로 바꾸어 적용하는 방법도 제시되고 있으나 이 경우 기본적인 강도나 강성을 유지하기 위한 단면의 형성과 각 부분을 용접하는 과정에서 많은 제작기간과 특별한 기술력을 필요로 하게 된다.As a way to reduce the weight of the body, a method of changing the material of the car body to aluminum has been proposed, but in this case, a lot of manufacturing time and special technical skills are required in forming the cross section and welding each part to maintain basic strength or rigidity.

그리고 본 발명에 따른 철도차량용 차체는 이상과 같이 구성된 샌드위치 패널(10) 즉, 알루미늄 하니콤, PMI 폼, 우레탄 폼 등으로 이루어진 심재(12)와 보강섬유(탄소섬유, 유리섬유, 케블라 등)에 기지재료(에폭시 수지, 페놀수지 등)를 함침하여 반경화시킨 프리프레그로 이루어져 상기 심재(12)의 양측에 접착된 제 1, 2 표피재(14, 14')로 구성되며 철도차량의 내장설비의 취부를 위한 복수의 프레임(16)이 소정 간격으로 삽입된 샌드위치 패널(10)을 이용하여 철도차량용 차체를 구성하는 측벽부, 천정부 및 단부를 일체로 성형하여 제작된다.And the vehicle body for railway vehicles according to the present invention to the sandwich panel 10 configured as described above, that is, to the core material 12 and reinforcing fibers (carbon fiber, glass fiber, Kevlar, etc.) made of aluminum honeycomb, PMI foam, urethane foam, etc. It consists of first and second skin materials 14 and 14 ', which consist of prepregs impregnated with semi-impregnated materials (epoxy resins, phenolic resins, etc.) and bonded to both sides of the core material 12. By using the sandwich panel 10 in which a plurality of frames 16 are mounted at predetermined intervals, the side wall portions, the ceiling portions, and the end portions constituting the railway vehicle body are integrally molded.

제작방법은 기본적으로 오토클레이브 안에서 고온, 고압, 진공 조건으로 성형하는 성형법을 적용하며, 구체적인 제조공정을 도 3을 참조하여 설명하면 아래와 같다.The fabrication method basically applies a molding method for molding under high temperature, high pressure, and vacuum conditions in an autoclave, and a detailed manufacturing process will be described below with reference to FIG. 3.

먼저, 철도차량용 차체를 구성하는 측벽부(2), 천정부(3) 및 단부(4)가 일체로 제작될 수 있도록 차체와 동일한 형상 및 크기로 몰드를 제작한다(S10). 이때, 측벽부(2)에 유리창을 설치하기 위한 개방부, 천정부(3)의 공조설비설치용 개방부, 단부(4)의 연결통로용 개방부는 제작된 몰드에 세퍼레이트(Separate)를 부착하여 개방부의 위치를 설정한 후 표피재 및 심재의 적층 시 개방부는 제외 할 수 있도록 한다. First, a mold is manufactured in the same shape and size as the vehicle body so that the side wall portion 2, the ceiling portion 3, and the end portion 4 constituting the railway vehicle body can be integrally manufactured (S10). At this time, the opening part for installing the glass window on the side wall part 2, the opening part for installing the air conditioning equipment of the ceiling part 3, and the opening part for the connection passage of the end part 4 are attached to the manufactured mold by attaching a separator to the opening part. After setting the position, the open part should be excluded when laminating the skin and core material.

다음으로, 상기 몰드 위에 탄소섬유, 유리섬유 또는 케블라 등으로 구성되는 보강섬유에 에폭시 수지 또는 페놀수지로 구성되는 기지재료를 함침하여 반경화시킨 프리프레그로 이루어진 제 1 표피재(14)를 적층한다(S20). Next, the first skin material 14 made of a prepreg, which is semi-cured by impregnating a reinforcing fiber composed of carbon fiber, glass fiber, kevlar, or the like with an epoxy resin or a phenol resin, is laminated on the mold. (S20).

다음으로, 상기 제 1 표피재(14) 위에 소정의 간격으로 철도차량의 내장설비의 취부를 위한 복수의 프레임(16)을 위치시킨다(S30). Next, the plurality of frames 16 for mounting the interior equipment of the railway vehicle at a predetermined interval on the first skin material 14 is positioned (S30).

다음으로, 상기 제 1 표피재(14) 위에 알루미늄 하니콤, PMI 폼, 우레탄 폼 등으로 이루어진 심재(12)를 적층한다(S40). Next, the core material 12 made of aluminum honeycomb, PMI foam, urethane foam, etc. is laminated on the first skin 14 (S40).

다음으로, 상기 심재(12) 위에 다시 탄소섬유, 유리섬유 또는 케블라 등으로 구성되는 보강섬유에 에폭시 수지 또는 페놀수지로 구성되는 기지재료를 함침하여 반경화시킨 프리프레그로 이루어진 제 2 표피재를 적층한다(S50).Next, on the core material 12, a second skin material made of a prepreg, which is semi-cured by impregnating a reinforcing fiber composed of carbon fiber, glass fiber, or kevlar, with a base material composed of epoxy resin or phenol resin, is laminated. (S50).

마지막으로, 상기 S20 단계 내지 S50단계를 통해 적층된 적층체를 고온, 고압, 진공 상태의 오토클레이브에서 성형한 후 탈형하면 된다(S60, S70)). 이때, 오토클레이브에서의 성형온도는 기지재료의 종류에 따라 달라지는데, 기지재료가 에폭시수지인 경우 약 130℃이상이다. 그리고 성형압력은 보통 2bar(20tonf/m2) 정도를 적용한다. Finally, the laminate laminated through the steps S20 to S50 may be molded in a high temperature, high pressure, vacuum autoclave, and then demolded (S60 and S70). At this time, the molding temperature in the autoclave depends on the type of the base material, when the base material is epoxy resin is about 130 ℃ or more. And the molding pressure is usually about 2bar (20tonf / m 2 ) is applied.

이상과 같이 본 발명에서는 종래에 적용되던 차체 구성 재질을 복합소재로 바꾸고 복합소재만이 가지고 있는 특유의 제작성을 활용함으로써 일차구조물로서의 충분한 강도를 갖는 경량화 차체구조를 개발하였다.As described above, in the present invention, a lightweight body structure having sufficient strength as a primary structure was developed by changing a vehicle body material used in the related art to a composite material and utilizing the unique manufacturability of only the composite material.

상술한 바와 같이 본 발명에 따르면 종래 차체 제작시 문제되었던 차체 경량 화의 문제와 제작공정의 복잡함 및 오랜 제작기간의 문제를 해결할 수 있다.As described above, according to the present invention, it is possible to solve the problem of the weight reduction, the complexity of the manufacturing process, and the long production period, which have been a problem in manufacturing a conventional body.

또한 일체 성형을 통해 접합부를 줄여 복합소재에서 취약할 수 있는 부분을 감소시킴으로서 일차구조물로서의 충분한 강도를 확보할 수 있어 차체의 안전성을 높일 수 있다.In addition, it is possible to secure a sufficient strength as a primary structure by reducing the joint portion by reducing the joint portion through the integral molding can increase the safety of the vehicle body.
