Clark. Birch or poplar plies are impregnated with phenolic resin and laminated together in a mold under heat (280 °F, 138 °C) and pressure for use as a lightweight structural material. Similar to plywood, Duramold and other lightweight composite materials like the similar Haskelite were considered critical during periods of material shortage in World War II, replacing scarce materials such as aluminum alloys and steel.
The material has some advantages over metal in strength, construction technique, and weight. A cylinder made of Duramold is 80% stronger than a cylinder made of aluminum. Over 17 varieties of Duramold were developed, using various combinations of types of wood in thin plies. The Duramold process has also been used to make radomes for aircraft, as well as missile bodies.
