| Abstract Scope |
Vaporizing foil actuator welding(VFAW) performs the joining by colliding the two dissimilar materials using high pressure, which generated by vaporizing aluminum foil. To vaporize the aluminum foil, a high-rate transmission of current pulse is applied to the foil and the high vaporization pressure is formed as a result. This pressure pushes the flyer sheet and it collides to the target sheet.
By applying VFA welding process, Al6061-T4 and carbon fiber plate were used for target and flyer sheet to attach both materials. A hole was drilled on the carbon fiber and aluminum sheets were located at the top and bottom side of carbon fiber. When the VFAW process was conducted in this setting, the flyer aluminum sheet was collided with other aluminum sheet, by passing through the hole of carbon fiber. As a result, both aluminum sheets were welded, and carbon fiber was bonded with them tightly. |
