Abstract
Polypropylene (PP) based materials are widely used because of their low cost, good processability and good balance of properties but its low stiffness and strength greatly hinders its even wider utilization. In order to overcome this, PP is reinforced with different fillers. In composites; the issue of interface between the filler and matrix is of importance. Thus in the present paper, the effect of cryo-ageing and subsequent thermal-annealing on the PP-talc filled composites have been studied to monitor its effect on the interface. The composites with talc of different particle sizes are examined for mechanical and structural properties after treatment. The mechanical properties are evaluated by testing its tensile strength and wear performance, whereas, the study of structural properties by FTIR and SEM reveals some structural changes. These results have further been discussed and evaluated to find out the effect of these treatments on interface of various selected talc filled PP composite.
