Abstract
This research focused on evaluating the ballistic impact behavior of polyester-reinforced woven ramie fibers combined with aluminum fiber metal laminates (FMLs). The materials were structured in four specific configurations: two types of ramie composites (2-layer and 3-layer) and two FML configurations FML 2/2 and FML 2/3. Ballistic performance was assessed through both experimental and numerical testing under a controlled firing angle of 90 degrees with 9 mm projectiles. The findings clearly showed that the FMLs had superior energy absorption capabilities compared to pure ramie composites, with the FML 2/3 configuration standing out, absorbing 52.69 J of energy. This highlights the enhanced ballistic resilience of hybrid laminates, especially with increased composite layers. Therefore, the FML, particularly the FML 2/3, exhibits a significantly higher energy-absorbing capacity, making it more effective in reducing projectile performance post-penetration. The FML 2/3 configuration showed the greatest reduction in residual velocity in both experimental and simulation results, indicating superior effectiveness in absorbing ballistic energy compared to the other configurations. This finding suggests that adding layers to the composite, especially in the FML configuration, enhances the material's resistance to projectile penetration and effectively decreases the projectile's residual velocity. However, additional research is necessary to gain a comprehensive understanding of the high-velocity performance of thermoplastic fiber metal laminates (FMLs), particularly for their potential use in industrial applications.
