The Part of HA on Mechanical Properties of PMMA(Polymethylmethacrylate)

Ashwani Nagar, Pooja Anand

Abstract


This study is centered around the part of nano hydroxyapatite particles on the mechanical properties of PMMA/ HA nanocomposites. So, as to accomplish a legitimate and homogeneous appropriation of HA particles in the polymer lattice, blender processing procedure was connected. Wear, pressure and three-point bowing tests were directed. It was watched that wear rate diminished by expanding in HA content in both air and manufactured spit. The consequences of pressure tests demonstrated that the expansion of 2.5 percent HA to PMMA advanced extreme compressive quality, yield quality and modulus while created to reduction prolongation at break. Additionally, it was explained that option of HA more than 2.5 wt% brought on abatement in both extreme compressive quality and pressure yield quality and an expansion in stretching at break. The aftereffects of three-point bowing tests on the PMMA concretes containing 2.5 percent HA showed the most extreme bowing quality worth and modulus among all the HA containing definitions. However, there was no immediate proportionality between the aftereffects of bowing tests and the HA content and the expansion of HA to PMMA (up to 10 wt%) did not change the bowing properties fundamentally.
