Effect of Melt Temperature and Holding Time on Mechanical Properties of Polypropylene Composites Bottom Ash Reinforced

Abstract

In this study, observing the effect of variations in melt temperature and holding time on the mechanical properties of polypropylene composite materials with coal bottom ash reinforcement has been done. This composite used a particle size of 200-250 mesh with a composition of 10%, and a polypropylene matrix of 90% by weight. Melting temperatures had a variation of 170°C, 180°C and 190°C, and holding times had a change of 0, 30 and 60 minutes. Bottom ash was washed with fresh water (room temperature) and warm water (80°C) until clean from impurities. The next process, bottom ash was drained at room temperature for 24 hours and dried at a temperature of 120°C for 3 hours. The test results showed the value of composite increases to 24.4% for tensile and 123% for flexure strength from the pure matrix strength. These properties were essential information for alternative engineering material research.
