Abstract

This investigation elucidates the drop-weight impact performance of the jute/epoxy composite laminates infused with zirconium dioxide (ZrO 2 ) at a filler loading of 5%, 10% and 15% in terms of weight by means of ultrasonication. The results reveal that the peak load increased almost linearly with filler addition for 5 wt% and 10 wt% ZrO 2 composites by 18% and 27% respectively. In contrast, a gradual reduction in energy absorption was observed, with values decreasing by 9% and 15% at 10 wt% and 15 wt% ZrO 2 loading. Damage assessment using both digital image analysis and ultrasonic C-scan demonstrated that the surface damage area was reduced by approximately 22% and 35% for 5 wt% and 10 wt% ZrO 2 composites, respectively, relative to the baseline, corroborating the improvement in peak load. A relationship between the damage area and peak force as well as absorbed energy were established and it provides a demarcation between the aforementioned parameters with respect to the filler ZrO 2 loading.
