본 발명은 철도 차량용 패널(Panel)에 관한 것으로서, 보다 상세하게는 구조 개선을 통해 물적 특성을 향상시킬 수 있도록 한 철도 차량용 패널에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel for a railroad vehicle, and more particularly to a panel for a railroad car that can improve physical properties through structural improvements.

일반적으로, 철도 차량에 사용되는 패널은 탑승자와 짐의 하중 및 차량의 하중을 안정적으로 지지함과 아울러 차량에 가해지는 충격 및 진동을 흡수하는 역할을 수행한다.In general, the panel used in the railroad vehicle stably supports the load of the occupants and luggage and the load of the vehicle, and also serves to absorb shocks and vibrations applied to the vehicle.

종래의 철도 차량의 출입문에 적용되는 패널은 스테인레스플레이트 사이에 다수의 스테인레스프레임을 삽입한 후, 용접으로 서로 결합시키는 과정을 거쳐 제작되고 있다.The panel applied to the door of the conventional railway vehicle is manufactured by inserting a plurality of stainless frames between the stainless plate, and then bonded to each other by welding.

이러한 구조의 패널은 그 제작공정이 복잡할 뿐 아니라 자중이 많이 나가는 문제점이 있다.The panel of such a structure has a problem that the manufacturing process is not only complicated but also its own weight.

이와 같은 문제점을 고려하여 최근에는 알루미늄 또는 합성수지 재질의 허니컴을 심재로 하는 샌드위치 패널이 선보이고 있다. 그러나 상기와 같은 샌드위치 패널은 경량이면서 굽힘 하중을 잘 견딘다는 장점이 있으나, 방음/차음 기능이 취약하여 소음이 심하게 발생되는 문제점이 있다.In consideration of such a problem, a sandwich panel based on a honeycomb of aluminum or synthetic resin has been recently introduced. However, the sandwich panel as described above has the advantage that it is light and withstands the bending load well, but there is a problem that the noise is severely generated because the sound insulation / sound insulation function is weak.

한편, 철도 차량의 바닥에 적용되는 패널은 합성수지 또는 합판이 주를 이루고 있다.On the other hand, the panel is applied to the floor of the railway vehicle is made of synthetic resin or plywood.

그러나 합성수지 패널은 그 재질적 특성상 화재 발생시 유독가스가 다량으로 배출되는 문제점이 있으며, 합판 또한 내수성 및 내화성이 취약하다는 문제점이 있다.However, the synthetic resin panel has a problem that a large amount of toxic gas is emitted in the event of a fire due to its material properties, plywood also has a problem that the water resistance and fire resistance is weak.

이는 결국, 철도 차량의 기능성 및 사용성을 상대적으로 저하시키는 결과를 초래한다.This, in turn, results in relatively deteriorating the functionality and usability of the railway vehicle.
