由于其特定的强度和刚度，汽车行业对碳纤维增强塑料的需求正在迅速扩大。需要大规模生产更轻质的车身，从而需要开发更低成本的材料和更低成本的制造方法。热压成型比传统工艺（例如热压罐工艺）所需的时间更少。在本研究中，选择的混合材料是碳纤维增强塑料-X5CrNi18-9不锈钢。对通过热压成型制造的混合材料进行了检查，以确定最佳的制造方法。考虑了温度、时间、压力等制造条件。进行拉伸试验和三点弯曲试验来检查混合材料的机械性能。此外，通过光学显微镜观察接合界面。结果表明，如果压力太高（>1.2 MPa），环氧树脂容易流失到外部。因此，确定适当的压力水平非常重要。通过弯曲实验检查混合材料断裂面。结果，通过热压成型制备的混合材料在碳纤维增强塑料和X5CrNi18-9不锈钢表面之间表现出良好的粘结力。
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.
