Title:
METHOF FOR MANUFACTURING LEAFSPRING WITH ELECTRODES FOR RAILCAR TRUCK
Document Type and Number:
WIPO Patent Application WO/2017/043079
Kind Code:
A1
Abstract:
The method for manufacturing a leaf spring with electrodes for a railcar truck involves: a resin removal step in which parts of the surface of a fiber-reinforced resin, which is made of an electroconductive-fiber-containing resin, of the leaf spring are irradiated with a laser beam, thereby removing parts of the resin so as to expose parts of the electroconductive fiber; and an electrode formation step in which electrodes are attached to the exposed areas where the parts of the electroconductive fiber of the fiber-reinforced resin are exposed.
