Abstract :This study investigates the effects of nanoclay reinforcement and UV aging on the low-velocity impact resistance of polymer-based intraply carbon/aramid composites. Nanoclay particles, in concentrations ranging from 0% to 3% by weight, were incorporated into the composites. The impact resistance was examined experimentally, focusing on both the particle reinforcement and the impact of UV aging. Charpy impact tests were conducted on specimens subjected to 450 and 900 hours of UV exposure, alongside a control group. The results revealed that the composite reinforced with 2% by weight of nanoclay exhibited the highest impact resistance, with an improvement of 57.89% compared to the baseline. Although a reduction in impact resistance was observed after 450 hours of UV exposure, partial recovery occurred after 900 hours. Nonetheless, UV aging had an overall negative effect on the impact resistance of the materials. Additionally, scanning electron microscopy (SEM) was used to analyze the failure morphologies of the samples, providing insights into the damage mechanisms.
