摘要

The effect of carbon nanotubes (CNTs) on bending strength of calcium phosphate cement was investigated. The cement composite powders, containing 0, 0.2%, 0.4%, 0.6%, 0.8% and 1.0wt% CNTs respectively, were prepared by ball milling. It was found that the presence of CNTs improved the bending strength of the cement from 6.6 MPa to the best 10.5 MPa. The reason for mechanical property improvement is related to the fibers (bars)-like microstructure of the reinforcing element, with CNT in the core and hydroxyapatite crystals growing on it.
