Which type of fiber is commonly used in synthetic covering for aircraft?

The most commonly used fiber in synthetic covering for aircraft is fiberglass. Fiberglass is made from fine glass fibers and is known for its strength, light weight, and resistance to corrosion. These properties make it particularly suitable for the aviation industry, as it can provide structural support while minimizing the overall weight of the aircraft. Additionally, fiberglass can be molded into complex shapes, allowing for better aerodynamics and surface smoothness.

While polyester is used in some synthetic materials and applications, fiberglass is preferred for aircraft coverings because of its superior performance characteristics. Cotton, while historically used in earlier aircraft coverings, is not favored in modern aviation due to its susceptibility to rot and deterioration when exposed to the elements. Viscose, a type of regenerated cellulose fiber, is not typically used in aircraft coverings either, as its properties do not match the durability and strength required for aviation applications.
