According to the invention, there is provided a biomaterial composite, which comprises a polypeptide and a calcium phosphate compound, said peptide comprising the units of Formulas (I) to (III): [—(OC—(CH2)m—CO)p-(Pro-Y-Gly)n-]a??(I) [—(OC—(CH2)m—CO)q-(z)r-]b??(II) [—HN—R—NH—]c??(III) wherein m, p, q, Y, n, Z, r, R, a, b and c are as defined in the specification. The composite of the invention is particularly suitable for an artificial bone due to its high biocompatibility, high endurance and mechanical strength. Further, the invention can provide a process of the composite according to the invention can for preparation of the composite having excellent mechanical characteristics by a simple procedure.Type: GrantFiled: March 14, 2006Date of Patent: August 23, 2011Assignee: National University Corporation Nara Institute of Science and TechnologyInventors: Masanobu Kamitakahara, Masao Tanihara, Chikara Ohtsuki, Shinichi Ogata
