“…In summary, according to the literature review performed, we found that there are a number of key factors affecting NPR of AKFs such as: Influence of raw materials: fabrics manufactured using high-performance fibers exhibit higher NPR value and improved mechanical properties compared to fabrics manufactured using conventional fibers. 27,74,75 Influence of structural parameters: NPR improved strongly with the increase in loop length of knitted structures and NPR also increased with the decrease in cover factor and increase in course density of knitted fabrics. 22,76 Influence of fabric construction and auxetic structure type: (a) all fabrics knitted with the origami structure have auxetic behavior when stretched in both wales and courses directions, but the NPR values are different when the unit size changes; 65 (b) the NPR of V-shaped vertical folding fabrics are just the inverse of those of Z-shaped vertical folding fabrics.…”

Auxetic behavior is a promising new area for use in defense applications. In comparison to a conventional material, an auxetic material has superior properties because of having a negative Poisson’s ratio; it gets broadened when stretched or becomes smaller when compressed. Furthermore, auxetic materials have enhanced properties such as shear resistance, indentation resistance, fracture toughness, energy absorption, and so on. These improved properties make auxetic materials very appealing and have the potential to revolutionize their applications in aerospace, sports, automotive, construction, biomedical engineering, smart sensors, packaging, cushioning, air filtration, shock absorption and sound insulation, and defense personal protective equipment. This article examines the most recent scientific advances in auxetic materials and structures, such as auxetic textiles (fibers, yarns, and fabrics), auxetic textile-reinforced composites, and auxetic foams, as well as their exceptional auxetic behavior and various approaches to achieving them. Although many potential applications have been proposed, actual applications of auxetic materials in defense are still limited. This is an in-depth review article, and its main goal is to serve as a foundation for future studies concerning the topic.
