foams [16]. One alternative to honeycos and foams is porous ceramics directly derived from –or inspired by– natural cellular solids, often called biomorphic (or biomorphous) cellular ceramics [17-19]. Wood exhibits a true cell structure, some species such as balsa, pine or cork displaying nearly ideal honeyco structures.
