Auxetic fabrics are characterized by a negative Poisson's ratio, i.e. they expand transversely to the direction of loading under tensile load. As a structural element in composites, multilayer or 3-dimensional (3D) auxetic fabrics improve the impact strength and increase the energy absorption capacity. Textile materials are basically flexible. The deformation properties of fabrics are influenced by the fabric architecture. Due to the numerous advantages of auxetics, it is being investigated how auxetic structures can be introduced into the fabric architecture in such a way that the fabrics exhibit transversal auxetic behavior.
