What is the role of surface tape in aircraft fabric covering?

Surface tape plays a crucial role in sealing seams and preventing fraying in aircraft fabric covering. When fabric is applied to the structure of an aircraft, the seams where the fabric joins can be vulnerable to environmental factors such as moisture and UV exposure, which can lead to deterioration over time. The application of surface tape to these seams helps to provide a protective barrier that seals the edges of the fabric together. This not only helps to maintain the integrity of the covering but also reduces the likelihood of fraying, which could compromise the aircraft's overall safety and performance.

Additionally, properly applied surface tape contributes to a smoother surface finish and can assist with the aerodynamics of the aircraft, while also ensuring that the fabric remains taut and secure against the structure. This protective measure is essential in maintaining the longevity and performance of the aircraft’s fabric covering.
