Modeling the mechanical properties of Composites Reinforced by Silica nanoparticles through Response Surface Method & Regression Tree Method

An experimental study has been conducted on fracture toughness (KIC) and fracture energy(GIC) of composites reinforced by silica nanoparticles in this article. Three different diametersof 23, 74, and 170 nanometer nanoparticles were added to epoxy resin by up to 30 volumepercent. Two parameters, the size of the particles and the volume percent, have beenconsidered as the parameters affecting the above- mentioned properties. Moreover, these twoparameters have been considered as the input parameters for the purpose of modeling theresults through the response surface model method & regression tree method. Theexperimental results and the results of modeling indicate that adding silica nanoparticles has asignificant effect on Youngs modulus, fracture toughness and fracture energy in such…
