Abstract

In current research, in order to manufacture reinforced polypropylene composite with Carbon Fibers and CaCO3 nano-particles, polypropylene granules were fed to an extruder with specific percentages of maleic anhydride compatibilizer and calcium carbonate nano-particles and then extruded compound granules were hot-pressed inside a mold. After generating resin sheets from these granules, they were sandwiched between carbon fiber plain fabrics and heat-pressed, consequently samples of nano-composite are prepared. Standard mechanical tests of tensile, bending and impact were performed on prepared samples of both types of reinforced polypropylene composite with Carbon Fibers containing nano-particles and without nano-particles. Results showed that composite specimens containing calcium carbonate nano-particles endure 87% more tensile strength, 26% more bending strength and 40% more impact strength than specimens without nanoparticles. The maleic anhydride compatibilizer, due to formation of polypropylene-calcium carbonate copolymer, improves the uniformity of the compound and increases adhesion between polypropylene and calcium carbonate phases. Because of higher elasticity modulus of nano-particle compared to the polypropylene matrix as well as the possible nucleation of nano-particles in the polymer matrix, the overall strength of the nano-composite sample has increased. Also due to the symmetric shape of the quasi-spherical calcium carbonate nano-particles, these particles have isotropic properties in different directions and lead to an increase in the level of crystallinity in the polymeric matrix and the strength of the nano-composite. The dispersion of nano-particles in the polypropylene base causes the impact energy to be spread across the whole cross-section and thus the energy absorption capacity increases before fracture.
