In this research is proposed a relatively popular approach for fabrication of Hydroxyapatite- carbon nanotubes (HAp-CNT) composite, through suspension and hot press methods. The principle raw materials, namely suspensions of CNT and HAp were mixed with together to produce the composites with different wt% CNT. The sonicated suspension is dried at 110°C and subsequent was hot pressed at 500°C under 500 MPa uniaxial pressures. Microstructure and fracture surface of the composites were studied by scanning electron microscope (SEM). The results revealed that addition of 3 wt% CNT to HAp matrix resulted in an about 70% increase in bending strength of the composite.
