What is a possible indicator of fabric degradation?

Discoloration, brittleness, or cracking in fabric are significant indicators of degradation. When fabric experiences environmental stressors such as UV exposure, moisture, or temperature fluctuations, it may begin to lose its structural integrity and protective properties. Discoloration often signals chemical changes in the material, while brittleness can indicate that the fabric is drying out or becoming less flexible. Cracking typically suggests that the fabric is no longer able to withstand the stresses and strains it was designed for, which could lead to further deterioration if not addressed promptly. Recognizing these signs is crucial for maintaining aircraft safety and ensuring that the fabric covering remains effective in protecting the underlying structure.
