|De Havilland DH 83 Fox Moth|
The DH.83 Fox Moth was a successful small biplane passenger aircraft from the 1930s . . . Many components including the engine, tailplane, fin, rudder and wings were identical to those being used for the de Havilland DH.82 Tiger Moth then being built in large quantities as a military trainer. These were fitted to the purpose-built wooden, plywood-covered fuselage . . . - Wikipedia
An airplane made of plywood, haven't run across one of those lately. When was plywood invented? Wikipedia knows, or at least has an opinion:
The ancient Egyptians and Greeks cut wood thinly and glued it together in layers with the grain in perpendicular directions, making a versatile building material. In 1797 Samuel Bentham applied for patents covering several machines to produce veneers. In his patent applications, he described the concept of laminating several layers of veneer with glue to form a thicker piece – the first description of what we now call plywood. Bentham was a British naval engineer with many shipbuilding inventions to his credit. Veneers at the time of Bentham were flat sawn, rift sawn or quarter sawn; i.e. cut along or across the log manually in different angles to the grain and thus limited in width and length.
About fifty years later Immanuel Nobel, father of Alfred Nobel, realized that several thinner layers of wood bonded together would be stronger than a single thick layer of wood. Understanding the industrial potential of laminated wood, he invented the rotary lathe.
There is little record of the early implementation of the rotary lathe and the subsequent commercialization of plywood as we know it today, but in its 1870 edition, the French dictionary Robert describes the process of rotary lathe veneer manufacturing in its entry Déroulage. One can thus presume that rotary lathe plywood manufacturer was an established process in France in the 1860s. Plywood was introduced into the United States in 1865 and industrial production started shortly after. In 1928, the first standard-sized 4 ft by 8 ft plywood sheets were introduced in the United States for use as a general building material.
Artists use plywood as a support for easel paintings to replace traditional canvas or cardboard. Ready-made artist boards for oil painting in three-layered plywood (3-ply) were produced and sold in New York as early as 1880.
The idea has been around for a very long time, but it took the invention of the rotary lathe to make it commonplace.
