  • Railcar bogie plate spring
    Patent number: 9428199
    Abstract: A railcar bogie plate spring of the present invention includes: an upper surface member constituted by fiber reinforced plastic in which reinforced fibers are stacked so as to extend in a longitudinal direction; a lower surface member constituted by fiber reinforced plastic in which reinforced fibers are stacked so as to extend in the longitudinal direction; and a core member arranged between the upper surface member and the lower surface member. The core member is constituted by fiber reinforced plastic in which: reinforced fibers are stacked in a width direction perpendicular to a stack direction of the upper surface member and the lower surface member; and in a side view of the core member, the reinforced fibers are inclined relative to a bending neutral axis so as to intersect with one another.
