Title:
A manufacturing method of a jointing material
Document Type and Number:
Japanese Patent JP6199191
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a bonded material whose fire retardancy is secured while saving weight and which can be easily manufactured, to provide a manufacturing method thereof, to provide a body structure of a railroad vehicle, and to provide a body structure of traffic transportation means.SOLUTION: A bonded material 3 is a member in which a honeycomb structure 3c is bonded between paired plate materials 3a, 3b. The bonded material 3 is formed in approximately the same thickness as that of an exterior face plate or an interior face plate, for example, which constitutes a body structure of a railroad vehicle 2. The plate materials 3a, 3b are fire retardant magnesium alloy. It is preferable that the plate materials 3a, 3b be Mg-Al-Zn-Ca alloy or Mg-Al-Mn-Ca alloy for example. The honeycomb structure 3c is made of an aluminum alloy having void parts 3e. The honeycomb structure 3c is a honeycomb material (lightweight structure) including core parts 3f having a hexagonal cross-sectional shape or the like which are arrayed without a gap, and the void parts 3e are formed in the core parts 3f. An adhesion layer 3d is a layer that adheres the plate materials 3a, 3b and the honeycomb structure 3c to each other.
