A New Industry Comes Out of the Woods Plywood, the structural material of the future, takes to the skies today. Planes of many types are now being made of plywood, superior in certain char acteristics even to fine steel or aluminum. With war-time expansion of plane production, Fairchild foresaw shortages in the light metals. Research and engineering development of plywood at Fairchild were given a great stimulus. New data and new techniques were developed, made possible by recently perfected adhesives. Plywood crafts manship jumped ahead many years in a few short months. By a patented Fairchild process, known as DURAMOLD, layer-on-layer of wood, laid cross grain and permanently joined with special resins under heat and pressure, may now be molded into single and multi-curved structural surfaces of con sistently high quality. DURAMOLD possesses some distinct advantages over metal aircraft surfaces. It is more fire-re sistant. It makes lighter, stronger planes; the rigid DURAMOLD shell is its own support, eliminating the need for a great clutter of internal stiffeners, bulkheads, and other reinforcing members neces sary in thin metal construction. It does not wrinkle nor buckle in the airstream, as does a metal surface. There are no non-flush rivets, as no rivets are re quired. Thus, it is smoother in the air ... horsepower is not handicapped by increased "drag." The plane can fly faster, is more maneuverable and has greater lift and range in the field of high-speed performance. Production of DURAMOLD structures in spars, flat pieces, and complex curved surfaces is now concentrated within the aviation industry. Its pur poses are 100% the purposes of war. But, when victory is won, the techniques, facilities and crafts manship of a new industry can and will be applied to a multitude of peace-time products. DURAMOLD, another example of those Fairchild achievements which put the "touch of tomorrow in the planes of today," is available to all "priority" manufacturers. BUY U. S.
