Abstract
By using a duplex-coated carbon fiber felt, copper welding to aluminum is successfully developed. The first step of the welding method is that the felt is contacted and wrapped with molten aluminum, which is solidified under gravity pressure. The second step is that the aluminum-welded felt is contacted and wrapped with a molten copper, which is solidified under gravity pressure. The carbon fiber junction device is a fiber-reinforced alloy and acts as a joining part of copper and aluminum. Tensile strength of the junction device of carbon fiber reinforced Cu-25 at%Al alloy is higher than those of a Cu-25 at%Al alloy and an aluminum rod.
