Abstract
The demand for carbon fiber-reinforcement plastic is expanding rapidly in the vehicle industry because of its specific strength and stiffness. More lightweight vehicle bodies need to be mass produced, resulting in a need for the development of lower cost materials and lower cost fabricating methods. Hot-press molding requires less time than conventional processes, such as autoclave processes. In this study, the hybrid material chosen was carbon fiber-reinforced plastic-X5CrNi18-9 stainless steel. The hybrid material fabricated by hot-press molding was examined to determine the optimal fabrication. The fabrication conditions were considered with respect to the temperature, time, pressure, etc. A tensile test and 3-point bending test were conducted to examine the mechanical properties of the hybrid material. In addition, bonding interfaces were observed by optical microscopy. The results suggest that the epoxy resin tends to be lost to the outside if the pressure is too high (>1.2 MPa). Therefore, it is important to identify the appropriate pressure level. The hybrid material rupture faces were examined through a bending experiment. As a result, the hybrid material, which was fabricated by hot-press molding, exhibited good cohesion between the carbon fiber-reinforced plastic and X5CrNi18-9 stainless steel surfaces.
