High performance epoxy based EMI shielding hybrid composites were prepared and characterized for their mechanical, magnetic, and Electromagnetic Interference (EMI) shielding behavior. The aim of this research was to enhance the electromagnetic interference shielding effect of a nanocomposite at high frequency with good mechanical strength. The shielding effectiveness of the epoxy composite was improved via the addition of E‐glass/silver nanoparticle and nickel nanosheets. The reinforcements were silane surface modified to enhance the adhesion and dispersion of reinforcements with matrix. The composites were prepared via hand layup process using glass fiber, silver nanoparticle, and Ni nanosheets followed by room temperature curing. The characterization of hybrid composites was done in accordance with ASTM standards. The results revealed that the Ag and Ni along with E‐glass fiber improved conductivity, permittivity, and permeability of epoxy composite. Similarly, the mechanical behavior of nanocomposite was found to be increased for tensile, flexural, and Izod impact toughness. Moreover, a maximum wave attenuation of –48 dB was observed for 3‐mm thick composite shielding material in “J” band frequency. These mechanically sound high EMI shielding lightweight polymer composites could be used as potential material for aerospace, defense, tele‐communication, and satellite data transfer applications. Besides the reduction of EMI effect between electronic gadgets could improves the utility and life span of electromagnetic devices and gadgets in several engineering applications.
