Numerical analysis of mechanical properties of mesoporous silica and hydroxyapatite-polypropylene nanocomposites

Author

Abstract

This paper presents the numerical study on the mechanical properties of polypropylene (PP) reinforced with 1 wt.% (weight percentage) mesoporous silica (MCM-41), Hydroxy Apatite (HA) and the composite of MCM-41 and HA (MCM41-HA or MH) nanoparticles. Numerical simulation according to macromechanical method (continuum method) was performed for different form of Strain Energy Density Function containing: Marlow, Ogden and Van der Waals using the commercial software ABAQUS/CAE. In this research the hyperelastic behavior of porous polymeric nanocomposits containing: mesoporous silica/ polypropylene (PMCM), hydroxyapatite/polypropylene (PHA) nanocomposites and mesoporous silica- hydroxyapatite /polypropylene (PMH) nanohybrid in the uniaxial tensile test, three point bending test and Izod impact test were studied. In order to verify the numerical results, values obtained from the simulation of mechanical properties were compared With similar functional tests. The performed simulation results are in good accordance with the experimental data and the Marlow model has the best agreement with results of experiment.
