Influence of Mesoporous Silica Nanoparticles on the Mechanical Properties of Polypropylene: Experimental Studies and Simulations

In this paper the numerical and experimental mechanical properties of polypropylene (PP) reinforced with 1wt.% mesoporous silica (MCM-41) was investigated. The first step in achieving a valid product simulation forpredicting the behavior of porous polymeric nanocomposits is to perform simulations that can accurately reproduce theexperimental results. In this paper the hyperelastic behavior of porous polymeric nanocomposits in the tensile, flexuraland impact tests and by different form of Strain Energy Density Function containing Marlow, Ogden and Van derWaals were studied. In all cases, at least uniaxial stretching tests were required to fit the model and extract materialparameters. The performed simulation results are in good accordance with the experimental data and the Marlowmodel has better agreement with results of experiment.
