摘    要:对玻璃纤维(GF)增强聚甲基丙烯酸甲酯(PMMA)/羟基磷灰石(HA)复合材料的组成、成形条件和力学性能进行了研究。在PMMA中添加5%(质量分数)HA微粉的复合基体与增强材料GF复合,70~100℃的固化和模压成形,可得到密度为1.48g/cm3,具有生物相容性好、力学强度高、性能稳定和成形简单等特点的复合材料, 在骨外科修复中具有很好的应用前景。

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.
