Due to the extraordinary properties of carbon nanotubes (CNTs) and graphene, the nanocomposites with higher structural and functional properties compared to the matrix can be obtained with very small addition of carbon nano materials to the matrix. However, the mechanical properties of nanocomposites are about 10% lower than that of the fiber reinforced composites. In order to utilize the nanocomposites in the structural and functional applications, it is necessary to develop hybrid composites combined with micro fibers and carbon nanomaterials. Here, to incorporate CNTs and graphene into the fiber reinforced polymeric composite, the electrophoretic deposition (EPD) process has been utilized. Well-dispersed graphene nanosheets were introduced onto the carbon fiber surface in order to increase the interfacial strength between fiber and polymer matrix. Furthermore, graphene based nanocomposites with nanoparticles were investigated for photocatalysis and electrochemical catalysis.
