What material is recommended to apply on rib caps that are not rounded over?

Anti-chafe tape is specifically designed to protect areas on an aircraft susceptible to wear and tear, particularly where fabric may come into contact with sharp edges or less rounded surfaces, such as rib caps that are not rounded over. It provides a cushioning effect, preventing the fabric from fraying or wearing down over time, which helps maintain the integrity of the covering and extends its lifespan.

In contrast, fabric patches might not provide the same level of protection against abrasion in this situation, as they serve a different function, primarily for repairs or reinforcing areas. Adhesive tape can be useful but does not offer the same durability or protective qualities as anti-chafe tape in preventing wear due to friction. Meanwhile, a polyester cover is typically used for overall fabric covering rather than specifically addressing the needs of rib caps. Thus, anti-chafe tape is the optimal choice for ensuring that rib caps remain protected against damage, particularly when they have edges that could lead to fabric deterioration.
