Objective To evaluate the biological safety of continuous carbonfiber 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, cytotoxxicity, and mutagenicity were observed. Conclusion The continuous carbonfiber reinforced polyolefin composite material is of good biological safety. It meets all the demand made by biological safety as hardtissue repair material.
