What is the common type of fabric used in aircraft covering?

Nylon or Dacron is commonly used in aircraft covering due to its excellent strength-to-weight ratio, durability, and resistance to environmental elements such as UV light and moisture. These properties make it ideal for withstanding the rigors of flight and the varying conditions aircraft encounter during operation. Dacron, a type of polyester, specifically offers advantages such as low shrinkage, high tensile strength, and resistance to mildew, making it a preferred choice in the aviation industry.

While silk has historically been used, it is less common today due to its high cost and lower durability compared to synthetic fabrics. Cotton, while it was widely used in earlier aviation, has largely been surpassed by synthetic options that provide better performance and longevity. Polyester is a broader category that includes Dacron, but in the context of aircraft covering, Dacron or nylon specifically highlights the commonly used materials for effective and reliable fabric covering.
