Effects of Particle Size and Particle Loading on the Tensile Properties of Iron-Ore-Tailing-Filled Epoxy and Polypropylene Composites

The effect of particle size and particle loading on the stiffness and tensile strength of iron-ore-tailing-filled epoxy and polypropylene composites was investigated experimentally, and the results obtained are compared with calculations by various theoretical models. It was found that the stiffness of the materials increased with content of iron ore tailings.
