“…It also holds the fibers together and protects them from mechanical and environmental damage. 13 The author of this article, Lyu et al, 14,15 analyzed the macromolecular structure, aggregate structure, and morphological structure of waste feathers; explored the relationship between feather structure and sound-absorbing performance; and proved that waste feather fiber has excellent sound-absorbing performance. By exploring the sound-absorbing properties of different gradient layers of composite materials, researchers have shown that gradient composite materials have better sound-absorbing properties than ordinary composite materials.…”

To make full use of waste feather resources, waste feather fiber/polybutanediol succinate gradient sound-absorbing composites were prepared by a hot-pressing process with waste feather fiber as a reinforcing material and polybutanediol succinate as a matrix material. It can be applied to construction and other fields. The influence of gradient waste feather fiber mass fraction, gradient material density, and gradient material thickness on the sound-absorbing performance was studied, and the sound-absorbing mechanism of the material was analyzed. To determine the average sound-absorbing coefficient, maximum absorbing coefficient, and noise reduction coefficient as the evaluation index, the gradient sound-absorbing composites with waste feathers were compared with market common porous sound-absorbing materials with polyester fiber and wool fiber. The maximum sound-absorbing coefficient of the gradient sound-absorbing composites with waste feathers was 0.860; the average sound-absorbing coefficient was 0.408; the noise reduction coefficient was 0.393; and the noise reduction grade was IV. The sound-absorbing band was wide, and gradient sound-absorbing composites with waste feathers can be applied over a wide range.
