An auxetic material is one with a negative Poisson's ratio and has the property of widening when stretched or narrowing when compressed in contrast to conventional materials. Typical auxetic materials include modified polymeric foams (Lakes, 1987), regular honeycombs, polypropylene fibres and certai
Negative Poisson's ratio (NPR) foams have been predicted to have unusual acoustic properties. To measure these, polyurethane foam was chosen to serve as a model system. Negative Poisson ratios were produced in open cell, reticulated polyurethane foams by heat setting the foam which had been three-di
