Sophie Koch & Dr. Marion Frey - Delignified Wood-Polymer Composites

a) Schematic illustrating the fabrication of delignified wood reinforced polymer (DWRP) composites. Natural wood is delignified, resulting in a continuous open porous cellulosic scaffold that can be infiltrated with a polymer matrix. The combination of mechanical interlocks and bicontinuous phase structure allows for stress transfer in the composite.
