Abstract Functionally dual gradient type of carbon fiber reinforced epoxy composites, in which crosslinking density of epoxies and content of carbon fibers are gradually varied through the thickness, were fabricated by using centrifugal force. The spatial variation of fiber content and the crosslinking density change of epoxies were confirmed by checking densities and glass transition temperatures, respectively, along the thickness. The mechanical properties of the polymer composites were also measured.
