我们描述了一类新型伸缩(负泊松比)泡沫塑料的制造和力学性能，这种泡沫塑料可以呈现任意复杂的形状，并且可以大量生产。与传统的负泊松比泡沫塑料相比，采用新制造工艺生产的薄板样品在拉伸载荷下的泊松比行为分布更加均匀，在循环拉伸载荷下单位体积消耗的能量高达一个数量级。(C)2010年Acta Materialia Inc.由爱思唯尔有限公司出版。版权所有。
We describe the manufacturing and mechanical properties of a novel class of auxetic (negative Poisson's ratio) foams, which can assume arbitrary and complex shapes, and can be produced in large bulk quantities. Samples of sheets produced following the new manufacturing technique show a more uniform distribution of the Poisson's ratio behaviour under tensile loading compared to classical negative Poisson's ratio foams, and up to one order of magnitude higher energy dissipated per unit volume under cyclic tensile tensile loading.
