摘要：

The mechanical properties of hydroxyapatite-polyethylene com posites have been im proved by increasing the interfacial bond between the hydroxyapatite reinforcing particles and the polyethylene. Two types of surface treatment have been investigated: both use silane coupling of the hydroxyapatite, either with or without grafting of the polyethylene. These treatments have lead to the presence of a silicon-containing interphase promoting chemical adhesion and penetration of the polymer into cavities in the ceramic particles. The resultant bond has improved the mechanical properties and fracture behaviour of the composites.
