Preparation of Carbon Fiber Reinforced Si-HA Bone Cements Composites
Carbon fiber reinforced silicon-substituted hydroxyapatite (C(f)/Si-HA) bone cements composites were prepared by microwave chemical reaction with a later solidification process using carbamide,calcium nitrate,ammonium dibasic phosphate and ethyl silicate as raw materials,and buffer solutions of acrylic acid and itaconic acid as gelling agent.The influences of carbon fibers volume fraction,contents of coupling agents,sodium citrate contents on the flexural strength of silicon-substituted hydroxyapatite bone cements composites were particularly investigated.The phase composition,microstructures and flexural strength of the composites were characterized by X-ray diffraction,scanning electron microscope and universal testing machine analyses.And the flexural strength of the prepared composites reach the maximum value 41.5MPa when the carbon fibers volume fraction,silane agent KH550 and sodium citrate mass fraction arrive to 3.0,0.6 and 3.0%,respectively.
