Abstract: This article selects jute fiber as raw materials to make a certain bulkiness of automotive ornamental materials by using non-woven fabric technology and reinforced by the acupuncture processing to use as samples.We Test the sound absorption properties of these samples at different density.Then we mix the jute fiber with a certain content of aluminum fibers at different weight or mode and analyze the factors affecting on the acoustlc performance. The results showed that in the same test sound wave frequency, the sound absorption properties of jute carpet samples improve with the increase of surface density and the best density is 764 g/m2. Aluminum fiber is helpful to improve the acoustic performance and sound absorption properties of aluminum fibers increasing with the ratio of fiber.Imported aluminum-made fiber acoustic performance is better than aluminum fiber. In addition,the sound absorption properties is different with mixed mode. When the aluminum fiber mesh on the opposite of the jute carpeter , sound absorption coefficient is best, followed by positive, intermediate and mixed is the worst.
