OBJECTIVE: To evaluate the biological safety of continuous carbon-fiber reinforced polyolefin as hard tissue repair material. METHODS: Biocompatibility of the material was evaluated through hemolysis test, pyrogen test, skin irritation test, cytotoxicity test, ames test, in vitro chromosome aberration test, and bone marrow cells Micronuclei test. RESULTS: No obvious hemolysis, pyrogenic characteristics, sensitivity, cytotoxicity, and mutagenicity were observed. CONCLUSION: The continuous carbon-fiber reinforced polyolefin composite material is of good biological safety. It meets all the demand made by biological safety as hard tissue repair material.
