What is the consequence of inadequate fabric strength in areas of high stress?

Inadequate fabric strength in areas of high stress can lead to an increased risk of structural failure. Aircraft are subjected to various forces and stresses during operation, particularly in critical areas such as around control surfaces, wing attachments, and other components that experience significant aerodynamic loads. If the fabric covering lacks the necessary strength to withstand these forces, it may lead to tearing, fraying, or complete failure of the covering material.

This failure can compromise the integrity of the aircraft structure, ultimately endangering both the aircraft and its occupants. It is essential that fabrics used in aircraft covering meet specific strength and durability standards to ensure they can handle the stresses of flight. Thus, ensuring adequate fabric strength is crucial for maintaining the overall safety and reliability of the aircraft.
