Enhancing Ballistic Protection Through Fiber Metal Laminate Composite Analysis Using Finite Element Methods

On April 5, 2025, a research activity was conducted at the Laboratory of Metal Casting, Faculty of Engineering, Hasanuddin University, focusing on the advanced study of composite materials for personal protective equipment. This study, involving 5 participants, explored the structural behavior and energy absorption capability of Fiber Metal Laminate (FML) composites when subjected to ballistic impact, particularly in the context of anti-bullet vest applications.

Fiber Metal Laminates are hybrid materials composed of alternating layers of metal (such as aluminum) and fiber-reinforced composites. Their unique configuration offers a promising combination of strength, ductility, and lightweight characteristics. In this research, special emphasis was placed on determining the optimal positioning of aluminum plates within the laminate structure to maximize energy absorption during projectile impact. The study utilized Finite Element Method (FEM)-based computational simulations, enabling precise modeling of stress distribution, deformation patterns, and failure mechanisms under high-velocity impact conditions.

The findings of this research are expected to contribute significantly to the development of more effective and affordable ballistic protection systems. By optimizing material configurations through simulation rather than costly physical testing, this approach supports more efficient research and development processes. Moreover, the application of such advanced materials has the potential to improve safety for individuals in high-risk professions, including law enforcement and security personnel.

This activity directly aligns with several Sustainable Development Goals (SDGs), particularly SDG 1 (No Poverty), SDG 4 (Quality Education), and SDG 17 (Partnerships for the Goals). Through innovation in material engineering, the research contributes to SDG 1 by supporting the development of cost-effective protective technologies that can be more widely accessible. In line with SDG 4, this research serves as a platform for experiential learning and capacity building among participants, enhancing their technical competencies in simulation and advanced materials analysis. Furthermore, SDG 17 is reflected in the collaborative nature of the research, fostering partnerships among academic researchers and promoting knowledge sharing in the field of engineering.

In addition, the study also indirectly supports SDG 3 (Good Health and Well-being) by aiming to improve personal safety equipment, as well as SDG 14 (Life Below Water) and SDG 15 (Life on Land) through the promotion of efficient material usage and reduced experimental waste via computational methods.

Overall, this research represents a meaningful step toward integrating advanced engineering solutions with global sustainability goals. By combining scientific rigor with practical relevance, the project not only advances the field of composite materials but also contributes to broader societal impacts through innovation, education, and collaboration.
