“…2 As a renewable resource, natural fiber composites not only have biodegradability and renewability, but also have the advantages of light weight, economy, high strength, safety, 3 and low cost. 4 Poultry feather weight makes up about 7% of broiler weight. 5 It is estimated that around 8-9 million tons of waste feathers are produced every year in the world.…”

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.
