Abstract
- The present study is investigating the use of short carbon fiber (SCF) and silver‐coated hollow glass microsphere (Ag@HGM) reinforced epoxy light‐weight composites for electromagnetic interference (EMI) shielding applications in the X‐band frequency range (i.e., 8–12 GHz). The study found that Ag@HGM along with SCF significantly improved the dielectric properties of the composites and enhanced the EMI shielding effectiveness of 34.6 dB. Thermal analysis indicates that the sample shows a high rate of heat dissipation and good thermal conductivity. The dynamic mechanical analysis has indicated that the composite has improved storage modulus, glass transition temperature, and activation energy. Highlights: SCF and Ag@HGM epoxy composite is fabricated for EMI shielding application.Two steps: etching and electroless coating of HGM are used for silver coating.The addition of Ag@HGM has enhanced total SE from 27.4 to 34.6 dB.EM wave gets scattered, experiences internal reflections view SCF and Ag@HGM.Additionally, enhancement of thermal and mechanical properties is observed.
