Abstract

This study concerns the fabrication of polymer composites for use as jigs and racks. The objectives were achieved by conducting mechanical testing on polymer composites, with and without filler materials in order to evaluate their mechanical properties. Charcoal and wood flour was used as filler material, which were mixed with polypropylene at various percentages and then tested for tensile and flexural properties. The specimens were then examined to relate their performance with their content. A raw material cost reduction was estimated as to justify mass production of jigs and racks using polymer composites. From the testing, it was discovered that the addition of filler material reduced the strength while increasing the rigidity. The content of 30% charcoal and 30% wood flour is found to be optimal for filled polymer composites in this study as higher content of filler material renders the composite unsuitable for practical use. Also, it is estimated that using this ratio the resin cost can be reduced by up to 30%. For low load applications such as inspection jigs and shoe racks, the composite studied would prove to be suitable.
