Carbon fiber structural components increase the suppleness of in the key structures of automotive body parts, sometimes complementing a metal and sometimes acting as independent structural members. Intelligent interplay between carbon-fiber-reinforced plastic (CFRP), aluminum, and steel tunnels can be found in A, B, and C pillars, as well as in much of the roof, which are all built using CFRP/metal hybrid parts to reinforce the body [1]. CFRP and CFRP/metal hybrid structures have been used in several cases, and carbon/epoxy, glass/epoxy, and hybrid composites have been used in the reinforcement of structures [2]. The CFRP/metal hybrid composites were produced by stacking CFRP on a metal plate to enhance the specific mechanical properties relative to those of automotive structures [3,4]. For functional requirements, and for the repair and maintenance of mechanical parts, there is expected to be a growing need in the near future for automotive parts with a pass-through hole in CFRP panels, and CFRP/metal hybrid components. Accordingly, a study on how to produce circular and square holes in CFRP and CFRP/metal hybrid composites by a punching process is necessary. More specifically, the study of shear behavior can increase understanding of all punching processes for plastic and hybrid composites. One of the most important aspects of a punched surface is its quality. According to the investigation of the blanking of fiber-reinforced plastics, composite laminates with various types of fibers and polymeric matrices can be blanked with sharp edges by precise vibro-punching [5]. To obtain a significant through-hole by a piercing process in the actual production of a novel material such as a CFRP laminate, many technical issues should be examined and resolved. In a previous study, a thin CFRP laminate was pierced while varying conditions such as the clearance and the shape of the punch. The effect of the tool clearance and punch shape on the damage in the specimen was studied to optimize the punching process [6]. Also, mechanical conditions such as the tool clearance and the punch velocity in the shearing test were varied to determine the characteristics of unstable cutting of a 0.5-mm-thick polycarbonate (PC) specimen subjected to straight punch/die shearing [8]. Undoubtedly, previous research on the punching of metals, including aluminum alloy, magnesium alloy, and advanced high-strength steel, has provided much information on punch-shearing to clarify the effect of tool parameters and improve the quality of sheared edges by tool design [9–۱۳]. Furthermore, to obtain the material behavior during the punching process, it is more reliable to use the finite element method (FEM), analytical modeling, and experimental tests in combination than only an empirical approach [14]. Similarly, the use of a numerical simulation in conjunction with a punch-shear test on plastic materials has been presented.
