In this work; the differences between of electromagnetic properties of glass fiber reinforced (GFR)-epoxy laminate composites with various nanoparticle doped polyacrylonitrile (PAN) fibers were investigated. The laminated composites that made in specific molds were obtained by putting woven glass fibers between every PAN nano fiber mats. PAN nano fibers have three different nano modified configurations which pure, added multi-walled carbon nanotubes (MWCNTs) and added graphene. The prepared solution for electrospinning process contains 10wt% PAN. The solvent dimethylformamide was preferred to use as an excellent solvent for PAN materials. The morphologies of the PAN nano fiber mats were viewed by scanning electron microscope (SEM). The radar absorption efficiencies of the composites in the individual and different combinations were measured in the X band frequency range (3-10 GHz). Experimental results show that the produced graphene-added fiber laminated composite material has excellent microwave absorption effect at many points in the 3-10 GHz band.
