Aircraft fabric covering often used in the restoration of older types that were originally covered using traditional methods. The purposes of the fabric covering of an aircraft are: Pioneering aviators such as George Cayley and Otto Lilienthal used cotton-covered flying surfaces for their manned glider designs. The Wright brothers also used cotton to cover their Wright Flyer. Other early aircraft used a variety of fabrics, silk and linen being commonly used. Some early aircraft, such as A.V. Roe's first machines, even used paper as a covering material. Until the development of cellulose based dope in 1911 a variety of methods of finishing the
Fabric structure re-radiated energy (solar heat) to transmit through. Because of its energy efficiency, high melting temperature and lack of creep, fiberglass-based fabrics have been the material of choice for stadium domes and other permanent structures, particularly in the United States. However, when properly constructed, polyester structures may be equally durable. A number of polymers consisting mainly of polyethylene, polypropylene or combinations of the two are available for fabric structures. PVDF woven fabric are available for fabric structures. ePTFE woven fabric are available for fabric structures.. Blackout material, also known as blockout material, is an opaque fabric. Blackout fabric consists of a
