Duramold

Duramold was a trademarked process developed by Fairchild Aviation Corporation in the 1930s, referring to a method of manufacturing aircraft components from molded wood veneer impregnated with a thermosetting plastic resin. Primarily using urea-formaldehyde resin, the Duramold process involved layering thin sheets of wood veneer (often birch or mahogany) that were coated with the resin and then formed into the desired shape using heat and pressure in a mold. The resulting composite material offered advantages over traditional aircraft construction materials like aluminum alloy, including a smoother surface, reduced weight, and potentially lower production costs. The process allowed for the creation of complex, curved shapes without the need for rivets or seams, improving aerodynamic efficiency. Although considered promising for aircraft construction, the Duramold process was largely superseded by aluminum alloys and later composite materials like fiberglass and carbon fiber due to factors such as material limitations, production challenges, and the demands of larger aircraft designs. While not widely adopted after World War II, Duramold represents an important step in the development of composite materials in aviation.
