What does the reinforcement of fabric edges prevent?

The reinforcement of fabric edges is essential in maintaining the integrity and durability of aeronautical fabric structures. By reinforcing the edges, you protect them from potential cuts and abrasions caused by the lacing cords, which secure the fabric to the frame of the aircraft. Lacing cords can exert pressure and cause fraying or damage to the fabric if the edges are not adequately reinforced.

This safety measure ensures that the fabric remains securely attached and does not develop weaknesses that could lead to failure during operation. Reinforced edges serve as a buffer, significantly reducing the likelihood of cuts from the lacing cords, thus enhancing the overall longevity and reliability of the fabric covering. Other factors such as weather damage, wear and tear, and punctures, while important considerations in fabric maintenance, do not primarily result from the specific actions of lacing cords.
