From parachutes to orbiting systems, webbing structures play a crucial role on the safety of civil and aerospace systems. The mechanical strength of a webbing can be severely undermined by the ultra-violet (UV) component of sunlight. In this work, we introduce a photochromic webbing structure that exhibits color variation upon UV irradiation. The photochromic webbing demonstrates sensitivity under a wide range of realistic field settings, including extended UV exposures and cyclic UV irradiations. Our analysis could help set the stage for the integration of photochromic webbings in aerospace systems.

Abstract
From parachutes to orbiting systems, webbing structures play a crucial role on the safety of civil and aerospace systems. The mechanical strength of a webbing can be severely undermined by the ultra-violet (UV) component of sunlight. In this work, we introduce a photochromic webbing structure that exhibits color variation upon UV irradiation. The photochromic webbing demonstrates sensitivity under a wide range of realistic field settings, including extended UV exposures and cyclic UV irradiations. Our analysis could help set the stage for the integration of photochromic webbings in aerospace systems.File in questo prodotto:
