利用纤维状颗粒制备了多孔羟基磷灰石陶瓷，这些陶瓷中的大部分孔可以看作是开孔。将含有聚合引发剂的甲基丙烯酸甲酯单体在减压室中引入上述多孔陶瓷的开孔中;通过在60 °C下加热48小时使这种引入的单体聚合。扫描电镜观察表明，聚甲基丙烯酸甲酯（PMMA）存在于多孔HAp陶瓷内部。在各种多孔陶瓷材料中，HAp-PMMA杂化材料的断裂韧性最高可达3.2MPa·m1/2，是致密HAp陶瓷的1/4。
Some porous hydroxyapatite ceramics were fabricated using the fibrous particles; most of the pores in these ceramics could be regarded as open pores. The methylmethacrylate monomer containing the polymerization initiator was induced into the open pores of the above porous ceramics in a chamber under reduced pressure; such introduced monomer was polymerized by heating it at 60 °C for 48 h. The SEM observation showed that the poly (methylmethacrylate) (PMMA) was present inside the porous HAp ceramics. Among the HAp-PMMA hybrid materials derived from various porous ceramics, the highest fracture toughness was 3.2 MPa•m1/2, which was ˜ times higher than that of the dense HAp ceramics.
