What role does UV resistance play in the selection of aircraft fabric?

UV resistance is a critical factor in the selection of aircraft fabric because it enhances the fabric's lifespan under sunlight exposure. Aircraft often operate outdoors, where they are subjected to sunlight and ultraviolet rays. Over time, UV radiation can degrade materials, leading to loss of strength, discoloration, and overall deterioration of the fabric. By selecting a fabric with good UV resistance, manufacturers and technicians can ensure that the material will maintain its integrity and appearance for a longer period, thereby reducing the frequency of repairs and replacements. This property is vital for ensuring safety and performance during flight operations.
