The hydroxyapatite (HA) powder surface modified with silane coupling agent was used to prepare HA/epoxy composite. It was found that silane has greatly improved the dispersion of HA in epoxy. The composite has good in vitro bioactivity and biocompatibility with 40 wt% HA, and the flexural modulus is close to that of natural bone, but its strength is lower than that of natural bone. So the composite needs further reinforcement in some way or other.
