EFFECT OF TALC ON BENDING STRENGTH OF POLYPROPYLENE COMPOSITES

In this study the Polypropylene (PP) was taken as a base material. The PP composites were made with talc at various concentrations by weight. The specimens used for the experiments were made on Injection moulding machine (De- Tech 60LNC5 made by Larsen & Tubro). To obtain the test specimens the die was clamped onto the injection mould-ing machine. The talc was added and mixed manually in 10, 20 & 30% by weight and the specimens were made at 4, 5 & 6 MPa injection pressures. For performing the bending strength tests a NETZSCH bending stress test machine manufactured by GERATEBAU was used.
