Abstract :

Iron ore tailings (IOT) filled polypropylene (PP) composites were produced by reinforcing polypropylene with iron ore tailings which is a waste product. Particle sizes 53 �¼m, 75 �¼m and 100 �¼m were considered for different volume fractions of 0% to 40% at intervals of 5%. The thermal conductivity of the IOT filled PP composites was determined using the transient techniques employed in the KD2 pro thermal analyzer. 30% volume of iron ore tailings gave increase in thermal conductivity of the composite. Tensile test was conducted and the experimental results were compared with theoretical results obtained from suitable mathematical models. It was discovered that the smaller the particle size of the iron ore tailings, the higher the thermal conductivity and tensile strength. The thermal conductivity increases as the volume fraction increase for either particle size. However, the thermal conductivity and tensile strength start to fall from 35% to 40% because the polymer starts to lose its stability at these volume fractions.
