Abstract
Abstract Compounds of Polypropylene (PP) will continue to play as an important materials for automotive applications because of its good mechanical properties including mold ability combined with excellent appearance, colorability ,environmental suitability and high performance at low cost. PP compounds are used in automotive interior parts, instrumental panels, door panels, pillars, Loading platform for light pick-up trucks, battery boxes, indoor carpets. These parts easily porn to wear because of its frequent usage. In this work calcium carbonate(CaCO3) has been blended with PP in different proportions using twin screw extruder machine and tested it in Pin-on-Disc machine for varying load, speed and sliding distance to study its wear characteristics. The wear phenomenon has been investigated and discussed based on wear loss of the material and microstructure of worn surfaces.
