Different generations of biomedical materials are analyzed in this paper. The current clinical uses of plates made of metals, polymers or composite materials are evaluated, and nano hydroxyapatite/polylactic acid composites and carbon/carbon composite plates are introduced as emphasis. It is pointed out that the carbon/carbon composites are of great feasibility and advantage as a new generation of biomedical materials, especially in the field of bone plate. Compared to other biomaterials, carbon/carbon composites have a good biocompatibility and mechanical compatibility because they have similar elastic modulus, porosity and density to that of human bones. With the development of the technology in knitting and material preparation, carbon/carbon composite plates have a good application prospect.
