Abstract

This study examines the low-velocity impact performance of jute fiber-reinforced composites with natural rubber interleaving produced using compression molding. Additionally, research is done on how ageing affects impact attributes and visual damage. Understanding the behavior and durability of these materials over the long term is essential for improving design and engineering decisions in a variety of applications where impact resistance is vital. Testing for low-velocity impacts was done on specimens at 1, 7, 15 and 30 days old. The experiments were conducted using a drop-weight testing device that was instrumented. The findings indicated that as the compliant composites age, their energy absorption capabilities and impact resistance decrease. The overview of the impact performance of unaged sample is provided for comparison with the aged samples. The least aged compliant composite with one day ageing exhibits energy absorption of 35.79 more compared to 30 days aged composite. Also, maximum peak force of 3750 N which is 34.4 more compared to the most aged compliant composite with 30 days of ageing. Additionally, the extent of damage to natural rubber increases with aging. © The Author(s), under exclusive licence to The Brazilian Society of Mechanical Sciences and Engineering 2024.
