Abstract

MAGLEV coils are moulded in resins such as epoxy and sheet moulding compounds. But the durability of resins is not yet sufficiently known well enough. Moreover, the mechanical strength of their moulding resin is degraded by the alkaline content in the concrete component of the guideway to which propulsion coils are attached. We performed bending fatigue tests using test pieces compliant pursuant to ASTM, and examined the flexural properties of test pieces immersed in an alkaline solution.
