Evaluation shows composites with basalt fibers enhance impact absorption and prevent delamination, suggesting lightweight protective solutions.
This study evaluated the ballistic resistance and failure characteristics of composites reinforced with environmentally friendly and mechanically robust basalt fiber. Basalt fiber-reinforced polymer (BFRP) and a variant with embedded ceramic balls (BFRP-Cs) were fabricated and compared with conventional aramid fiber-reinforced polymer (AFRP). Ballistic tests were conducted using 5.56 mm NATO rounds in three velocity ranges, and damage was analyzed via CT X-ray to assess the penetration depth, interfacial failure, and delamination. BFRP showed higher ballistic resistance than AFRP in all ranges, as well as maintained non-penetration under high velocities. The BFRP-Cs showed efficient impact absorption relative to weight and thickness under medium velocities. These results confirm that basalt fiber-based composites can serve as lightweight alternatives to aramid composites for protective gloves and provide a basis for the future design and optimization of protective equipment.
