Conversion of Polypropylene (PP) Foams into Auxetic Metamaterials

Conversion of Polypropylene (PP) Foams into Auxetic Metamaterials

In this work, a simple and environmentally friendly process combining low pressure (vacuum) and mechanical compression is proposed to convert recycled polypropylene (PP) foams (28 kg/m<sup>3</sup>) into low density foams (90–131 kg/m<sup>3</sup>) having negative tensile and c...
