Mimicking natural biological structures allows us to exploit tried design concepts for advanced material solutions. Wood is an example of an interesting natural material to replicate, as it exhibits excellent anisotropic mechanical properties and performs well as a thermal insulator. We demonstrate a process of creating an anisotropic cellular structure, a solid foam from forest-derived bio-constituents. As such, the resulting material has anisotropic mechanical properties such as elastic modulus and yield stress and exhibits complex mechanical response similar to natural wood. This novel paper recyclable material can be used as a substitute for oil-based packaging and insulation foams such as expanded polystyrene or polyurethane.
