WebSong et al. [ 31] used a chemical method to graft hydroxylated CNTs onto oxidized carbon fibers to improve polyimide’s mechanical and tribological properties as a matrix and prepare multiscale reinforced composites. WebIn this study, carbon nanotubes (CNTs) were grown on carbon fiber (CF) substrates to improve the surface area and, in turn, increase the adhesion between epoxy-resin and CFs. Nickel (Ni) was used as the catalyst in CNT growth, and was coated on CF sheets via the electroplating method.
