In a groundbreaking study published in ‘Composites Part C: Open Access,’ researchers from the National University of Sciences and Technology (NUST) have made significant strides in the development of lightweight composite armor plates designed to withstand ballistic impacts. Led by Hasan Aftab Saeed from the Department of Mechanical Engineering, this research addresses a critical need in both military and civilian sectors for effective protection against various threats while maintaining mobility and reducing weight.
The study utilized nonlinear finite element analysis to explore the ballistic performance of composite bi-layered armors made from Weldox 460 E, AA7075-T6, and silicon carbide (SiC) under blunt projectile impacts at velocities ranging from 100 to 400 meters per second. “The complexity of designing effective lightweight armor lies in the selection of materials, their configuration, and the gaps between layers,” Saeed explained. His team’s findings reveal that incorporating a ceramic front plate significantly enhances ballistic performance, leading to a promising combination of SiC and AA7075 that emerged as the lightest and most effective solution.
The implications of this research extend beyond military applications. In the construction sector, where safety and durability are paramount, the insights gained from this study could revolutionize the materials used in protective gear and structural components. Lightweight armor solutions may find their way into construction machinery, protective barriers, and even personal protective equipment, enhancing safety without compromising performance.
Moreover, the study highlights the superior ballistic capabilities of the AA7075-Weldox combination, which not only outperformed monolithic Weldox plates but also achieved weight reduction and minimized thickness. This innovation is particularly relevant for industries that require robust protection without the burden of heavy materials, potentially influencing the design of everything from armored vehicles to protective structures.
As the demand for advanced protective materials grows, the findings from this research could lead to new commercial opportunities and partnerships. Companies in the construction and defense sectors may look to collaborate with academic institutions to further develop and implement these innovative materials. “Our research paves the way for future developments in composite armor technology, which could redefine standards in safety and performance,” Saeed noted.
This study not only contributes to the scientific community but also serves as a catalyst for innovation in industries that prioritize safety and efficiency. The potential applications of these findings are vast, and as the construction sector continues to evolve, the integration of lightweight, high-performance materials will likely play a crucial role in shaping its future.
