Study on the properties of denture base materials made from PMMA filled with Al2O3/ZrO2 was carried out. The amount of Al2O3/ZrO2 filler was fixed at 5 wt%. However, the ratio of Al2O3 to ZrO2 added was from 0 to 100. Samples were prepared for fracture toughness, flexural strength and tensile tests. The fracture surface was analyzed using SEM and EDS. It was found that for Al2O3/ZrO2 of 80:20 ratio shows the highest fracture toughness and flexural properties. SEM micrographs indicate that distribution of Al2O3 and ZrO2 in the PMMA matrix is fairly homogeneous. The interface between the reinforcement particles and matrix is good. Therefore, addition of Al2O3/ZrO2 in PMMA is able to improve the mechanical properties of this denture base material. 2010-11-01T08:53:23Z 2010-11-01T08:53:23Z 2010-06-09 Working Paper p.189-195 978-967-5760-02-0 http://hdl.handle.net/123456789/10154 en Proceedings of the International Conference on X-Rays & Related Techniques in Research & Industry (ICXRI) 2010 Universiti Malaysia Perlis School of Materials Engineering & School of Environmental Engineering |
