to improve the properties of carbon fiber reinforced HA composite. Many methods have been reported to prepare ceramic coatings on carbon fibers, such as sol-gel, and electro-deposition[8-12..., the spectrum of untreated carbon fiber was a smooth curve without any peaks. However many obvious absorption peaks appeared on those of treated carbon fibers. On the spectrum of HNO3 treated fibers......
