Abstract
Since the nickel (Ni) coating on carbon fibers (CF: 7μm-diameter) prevented carbide formation and enhanced the ability of fiber wrapping by molten metal, a new method with extremely large friction force by broad interface of Ni coated CF was developed for Metal/Epoxy-CFRP joints with and without carbon fiber reinforcement (CFR). The CFR enhanced not only the tensile strength, but also the safety level of reliability remarkably. The σ_b and ε_b of Ti/NiCF/CFRP(Epoxy) are approximately three times higher than those of Ti/NiCF/CFRP(ABS). It could be explained, when the resistance to fiber pull out of Epoxy/CF is much higher than that of ABS/CF. Consequently, the new joint method by using carbon fiber remarkably enhanced the safety level with lightweight and high resistance to fracture of Ti/NiCF/CFRP(Epoxy) and Ti/NiCF/CFRP(ABS) utilized for airplanes and automobiles, respectively.
