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.

Lenticular fabric Lenticular fabric A lenticular fabric is a lattice-like arrangement of lens-shaped materials formed into a thin layer. When the surface of the fabric is smooth, it often has a reflective and light-distorting appearance. Lenticular fabrics are found in nature. Geological forces can produce lenticular fabrics consisting of quartz "microlenses" in clay deposits. Lenticular fabrics can be created through biological processes. For example, termites create these fabrics by combining sand with fibrous faeces to create plastic-like translucent barriers. Manufactured lenticular fabric is used to make movie projection screens, so that the image will appear sharper and brighter. Lenticular fabric often used
