S. Kaliskiego Street 2, 00-908 Warsaw, Poland The auxetic composites are materials characterized by a negative Poisso n’s ratio value. Such composites can be made of conventional materials with a positive value of Poisson’s ratio, but the specific arrangement of the composite reinforcement structures provides this composition with a negative Poisson’s ratio. It is also po ssible to create such structures from already existing auxetic subassemblies. In comparison to conventional composites, the auxetic reinforced ones have a lot of positive features, i.e.: higher shear resistance, better crack resistance and better damping properties. The aim of this article was to present the review of elastomeric materials for the possible application as the matrix for composite reinforced by auxetic fabrics, especially fabrics made of Helical Auxetic Yarn (HAY).

1. Introduction The auxetic composites are characterized by a negative Poisson’s ratio value. This parameter determines the amount of lateral expansibility referred to the amount of axial compression (Fig. 1). Such composites can be made of conventional materials with a p ositive value of Poisson’s ratio, but the specific arrangement of the composite 1.
