오토클레이브 성형된 길이 23m 복합재 철도차량 차체의 구조적 특성평가

​

This paper explains manufacturing process and experimental studies on a composite carbody of Korean tilting train. The composite carbody with length of 23m was manufactured as a sandwich structure composed of a 40mm-thick aluminium honeycomb core and 5mm-thick woven fabric carbon/epoxy face. In order to evaluate structural behavior and safety of the composite carbody, the static load tests such as vertical load, end compressive load, torsional load and 3-point support load tests have been conducted. These tests were performed under Japanese Industrial Standard (JIS) 17105 standard. From the tests, maximum deflection was 12.3mm and equivalent bending stiffness of the carbody was 0.81 $\times$ 10 $^{14}$ kgf $\cdot$ mm $^{2}$ Maximum stress of the composite body was lower than 12.2 $\%$ of strength of the carbon/epoxy. Therefore, the composite body satisfied the Japanese Industrial Standard.
