As electronics have become highly integrated and highly efficient, negative effect of electromagnetic (EM) wave should be minimized in broadband. EM interference (EMI) shielding materials, metal and carbon materials have been used as outstanding reflector and effective absorber, respectively. Although many studies have been reported for composites produced via chemical or thermal processes to cover broadband, the processes are complex and expensive. In this study, aluminum/carbon fiber composites were simply fabricated for shielding and absorbing EMI in broadband via mechanical process. Furthermore, EMI shielding ability of the composites was maximized by multi-layer structure of aluminum and carbon fiber to induce internal multiple reflection with consideration of the number of layer. The fabricated conditions of temperature and pressure were optimized by comparing the microstructure and electrical conductivity of the composites. Thus, a correlation between the number of sheets and the EMI shielding effectiveness will be discussed in this study.
