A purpose of this study is the development of high performance bio-ceramic composite materials, which have excellent mechanical properties and high fracture toughness as several times of characteristics of the human bone. For the purpose, the hydroxyapatite (HAp), which had excellent bio-compatibility and biotic activity, was reinforced by carbon fibers (CF) having bio-adaptability. The microstructures and the mechanical properties were evaluated. The compressive strength of the bio-ceramic composite material manufactured by carbon fiber oxidized for 15 hours (CF-15/HAp) was excellent about 3 times of the of the bone, the Young's modulus was nearly equal to that of the bone and the microstructure showed the strong bonding between HAp and CF. Therefore, this CF-15/HAp composite material was considered to be effective on the utilization as a high performance biomaterial.
