Abstract
The aim of present research work is to study the erosive wear response of epoxy based marble dust filled aramid bidirectional fabric-reinforced polymer composite. In this respect the aramid bidirectional reinforced epoxy based composites are fabricated with varying the proportion of marble dust (0, 10 20 and 30 wt.%). Steady state erosion test is performed on different impingement angle to investigate the erosion behavior of composites. The results reveal that erosive resistance of the composites is increasing with incorporation of marble dust and exhibit semi brittle erosion behavior. To increase the performance of erosive wear resistance of fabricated composites L16 orthogonal array design of taguchi method is implemented. Marble dust content, Impingement angle, erodent size and impact velocity are considered as control factors under the set of design experiments. Impact velocity shows significantly effect on the erosion response of marble dust filled aramid fiber reinforced epoxy composite.
