foaming process by using multilayer orthogonal auxeticstructure as reinforcement and polyurethane foam as matrix. The negative Poisson’s ratio (NPR) effect and mechanical behavior of the composite under a quasi-static compression were investigated and compared with those of the pure polyurethane foam and non-auxetic composite. The results obtained after the study show that the auxetic composite fabricated has an obvious NPR effect and behave more like a damping material with a large range of deformation strains [ 15 ]. Even though studies on auxetic composites exist in
