The objective of this study is to investigate the effect of the HA content to the pore characteristic of porous PCL/HA composite. To achieve this objective, the foaming condition which are temperature, pressure and depressurized rate are manipulated. The foaming process was performed in the 35, 40 and 45 ◦C temperature range and pressure 10, 20, 30 MPa in order to control the final morphology, porosity and pore structure of the composite foams. The depressurized rate and duration PCL/HA are constant at less than 1 min & 4 hour respectively. The result in this study found that present of HA content significantly affect the pore structure and characteristic.
