Abstract During the Joseon Dynasty, light and convenient leather armors were developed to replace metal armors, which were heavy and difficult to manufacture. Leather armors allowed easy movement of the troops and, because arrows were the primary weapons at the time, provided them with protection. The excellent performance of leather armors can be attributed to their materials and manufacturing method. The scales of the leather armor relics are prepared by layering animal skins, attaching them with natural glue, and then coating their outer surface with lacquer. The lacquer extracted from the lacquer (Ott) tree is an excellent material with high strength, waterproofing and antiseptic properties, insect repellency, heat resistance, as well as chemical resistance. The superior performance of the leather scale was reported in old scripts; however, it has not been proven through scientific analysis and testing. Therefore, in this study, the physical and mechanical properties, impact resistance, and anti-stab performance of leather scales manufactured following the traditional method were investigated. The results confirmed the excellent protection, impact resistance, and mechanical properties of the leather specimens glued with fish glue and coated with lacquer compared to those of specimens glued with synthetic glue and uncoated specimens glued with fish glue. This study reveals the excellent properties of fish glue and lacquer, which enable them to be used in various industries. |
