Abstract

Reinforcement with bioresorbable polymer such as PLGA is one of the useful ways to improve the mechanical property of brittle carbonate apatite (CO₃Ap) foam. In the present study, CO₃Ap foam was reinforced with various concentrations of PLGA solution (5, 10, 15 and 20 wt%) using vacuum infiltration method and its influence on structure, porosity and mechanical property was investigated. It was found that the amount of PLGA inside the hollow space of the CO₃Ap foam strut increased with the concentration of PLGA. Porosity likewise was significantly (p<0.05) reduced from 94% (CO₃Ap foam without PLGA) down to 82% (CO₃Ap foam reinforced with 20 wt% PLGA). Compressive strength of CO₃Ap foam significantly (p<0.05) increased from 0.02 MPa (CO₃Ap foam without PLGA) up to 1.5 MPa (CO₃Ap foam reinforced with 20 wt% PLGA).
