This study demonstrates the potential of an interconnected graphene nanointerface to enhance the mechanical and biotribological properties of carbon fiber-epoxy-hydroxyapatite composites. The results show that the graphene nanointerface improves the uniform formation of hydroxyapatite, promotes the bonding of fiber/matrix interface, and enhances the mechanical strength and wear resistance of the composites.
Interface is critical for the short-term and long-term performance of carbon fiber-epoxy-hydroxyapatite (CHE) composites for orthopedic implant applications because the stress transfer from the matrix to the fibers is via the interface. Herein, a novel type of interconnected graphene (IGE) nanointerface was fabricated in CHE by chemical vapor deposition method with a porous and radially aligned structure being achieved. Effects of IGE on morphology and microstructure of hydroxyapatite coating, mechanical and biotribological properties of CHE were investigated. The results show that IGE could induce the uniform formation of hydroxyapatite, favor the infiltration of epoxy, and promote the bonding of the fiber/matrix interface and the cohesion strength of epoxy matrix, thus enhancing the mechanical and biotribological properties of CHE. Compared with CHE, the tensile strength of IGE modified CHE increased by 21.9 %, and the wear rate of IGE modified CHE decreased by 93.4 %. This work demonstrated the potential of IGE as an interface for mechanically-strong and wear-resistance CHE. IGE-CHE possessing excellent mechanical and biotribological properties has potential application for bone replacement and bone fracture plate.
