Airplanes are dream worthy mover machines. Titanium and its alloy have been applied for air-compressor at the front of jet engine cover. On the other hand, carbon fiber reinforced polymer (CFRP) has recently applied for not only wing, but also fan breads of new turbo fan engines. To prevent impact force, leading edge of titanium is often mounted on the CFRP fan breads by adhesive. It is difficult to weld the bread. In order to enhance the joining strength, a carbon fiber reinforced interface has been suggested. To prevent to decay the carbon fiber felt by reaction to metal matrix, the fiber has been coated with nickel film, which protects the carbon fiber against titanium liquid. One side plain of the coated fiber felt is dipped into titanium liquid. After solidification, another side of the coated felt is also dipped in the polymer. The nickel coated carbon fiber reinforced interface between CFRM and CFRP probably acts as one of ideal joining methods.
