Flexural Strength of Poly Propylene Fiber Reinforced PMMA
Journal Title: International Journal of Pharmaceutical Science Invention - Year 2017, Vol 6, Issue 2
Abstract
Poly Methyl Methacrylate based restorations are widely accepted in dental and medical field due to the excellent biocompatibility and easy fabrication, however these restorations exhibit inferior mechanical properties. Therefore, the present study conducted to enhance the flexural strength of PMMA based material by reinforcing conventional PMMA with poly propylene fiber. 10 different test groups were prepared by varying the weight percentage (2.5, 5 & 10 Wt %) and aspect ratio (3mm/220μm, 6mm/220μm & 12mm/220μm) of the poly propylene fibers. Results obtained were statistically analyzed using One – Way Anova followed by Tukey Kramer multiple comparison test. All fiber reinforced test groups showed improved flexural strength and 6mm long fiber in 2.5 Wt% showed the highest flexural strength among the fiber reinforced test groups.
