摘要：

A new type of hybrid material was designed and created by reinforcing periodic cellular metals (PCMs) with rigid polyurethane foams. Two different PCM geometries and two types of rigid polyurethane foam were used to create four different hybrid materials. These novel materials may find useful application as cores in sandwich structures. The two-phase foam/PCM hybrids offered comparable stiffness and up to 59% higher strength as well as up to 86% higher resilience than the PCMs alone. Furthermore, the two-phase foam hybrids were up to 46% stronger and up to 63% stiffer than the one-phase foam hybrids.
