Boron alloy sheet/CFRP 복합소재의 접착특성 및 기계적특성 연구

다국어 초록 (Multilingual Abstract)

Light weight vehicle has been required more and more in order to Increase fuel efficiency and to reduce CO² that cause global warming. The demands has been developed advanced composite materials such as aluminum, magnesium alloys and CFRP(Carbon fiber reinforced plastic). The advanced composite materials are being developed and used in the various industries such as automobile, aerospace, high-speed train and other construction. Recent, Al/CFRP or steel/CFRP hybrid materials have investigated to apply this material in automobile industry. It is essential that lower time and lower cost fabricating should be followed first. In this study, Hot-press molding method is used to reduce time and cost. Boron steel/CFRP was made by hot-press molding in temp 140℃ and 0.4㎫. This method is faster 8 times than autoclave. But hot press molding method needs hybrid materials that have good bonding strength and mechanical properties. After boron steel/CFRP hybrid materials were made by hot press molding, bonding strength and mechanical properties were investigated through 3-point bending test, simple tensile test and shear test. Coated and uncoated boron steel sheet were used to know how coating affect bonding strength. In the shear and T-peel test, uncoated boron steel/CFRP hybrid materials became better than coated boron steel/CFRP.
