文摘

Carbon-nanofiber (CNF) reinforced aluminum (Al) matrix composites were fabricated by a unique liquid pressing process. The mechanical properties of the CNF–Al composites, both with and without titanium dioxide (TiO₂) coating layers on the CNF surface, have been studied. The compressive yield strength of the TiO₂ coated CNF–Al composite dramatically increased (over nine times), as compared with that of an Al alloy. TiO₂ coated CNFs are expected to be a highly sustainable and dispersible reinforcement for metal matrix composites (MMCs) that are fabricated by a metal melting process.
