What is one effect of UV exposure on aircraft fabric?

UV exposure on aircraft fabric leads to discoloration and brittleness due to the degradation of the material's structure. When fabric is regularly subjected to ultraviolet rays from sunlight, the energy from the UV radiation causes chemical changes in the fibers. Over time, these changes weaken the fabric, resulting in a loss of flexibility, which can compromise the performance of the aircraft cover. The discoloration occurs as the dyes and other finishes on the fabric deteriorate, leading to an aesthetically unpleasing appearance and reduced protective qualities. This degradation is crucial for maintenance and safety considerations in aviation, as a fabric that has become brittle may not withstand the stresses of flight effectively. Therefore, understanding the impacts of UV exposure is essential for ensuring the longevity and safety of aircraft fabric coverings.
