▎ 摘　　要

NOVELTY - A carbon nano tube and graphene-reinforced calcium phosphate bone cement composite material comprises 94.2-95 pts. wt. alpha-tricalcium phosphate, 4.8-5.2 pts. wt. hydroxyl apatite, 0.2-1 pts. wt., preferably 0.6 pts. wt. graphene and 0.2-1 pts. wt., preferably 0.6 pts. wt. carbon nano tube. USE - Carbon nano tube and graphene-reinforced calcium phosphate bone cement composite material for use in human bone repair and replacement (claimed) and treatment of other bone diseases. ADVANTAGE - The composite material has good strength and biocompatibility, reduced condensing time, and improved toughness. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a method for preparing a carbon nano tube and graphene-reinforced calcium phosphate bone cement composite material (2) a calcium phosphate biological bone comprising a carbon nano tube and graphene-reinforced calcium phosphate bone cement composite material.
