Cellular Materials' Periodic Cellular Materials (PCM) are a new class of structurally efficient multifunctional materials. PCM structures are based on an array of 3-D symmetric core topologies. They can be manufactured in a variety of core topologies including CMI's proprietary MicrotrussTM core designs.
