Abstract:The composition, forming condition and mechanical properties of the glass fiber reinforced poly methacrylic acid / hydroxyapatite biomedical composite material were studied. Poly methacrylic acid with 5% hydroxyapatite powder (mass fraction) was composited with glass fiber as reinforcer , after solidify and molding at 70～100℃, the biomedical composite material with density of 1.48g/cm3, fine biocompatibility, simple process and high impact toughness could be obtained, which provides good application prospect in bone surgery renovation.
Key words: PMMA; HA; composite material
