Patent ID: 10350857

Abstract:
An object of the present invention is to create, from a titanium alloy and an FRP prepreg, a composite of a titanium alloy and an FRP material that is suitable for bolt fastening. The composite can bring out excellent characteristics in CFRP members in mobile electronic-electric devices, mobile equipment, medical instruments, marine devices and the like. It has been found that titanium alloy having a special constant surface shape adheres strongly with an epoxy adhesive. In a composite obtained using this technique to integrate a titanium alloy member as a cover material and a CFRP material, the metal alloy portion deforms and disperses locally strong forces so that the CFRP material is not damaged, even when the composite is assembled to another metal member through bolt-fastening. As a result, the composite is expected to be effective for applications in mobile equipment or mobile device casings, where lightweightness, corrosion resistance, toughness and ease of assembly are required.
