Investigation on the sound absorption of multilayered woven and nonwoven fabrics with different bonding conditions

Abstract In this study, multilayer composite was fabricated by the lamination of woven and nonwoven fabrics for sound absorption applications. These fabrics exhibited different weaving densities and thicknesses, and were compounded through different methods including adhesives bonding, stich bonding, and facile plying‐up. The structure, mechanical, and sound absorption properties of laminated composites were investigated. It was found that the construction form plays an important role for enhancing the properties of multilayered composite. The sound absorption efficiency of multilayered composite can be improved by optimizing the combination of woven and nonwoven fabrics. This work has provided a valuable reference for the future development of sound absorption materials, and is also benefit for the utilization of textiles in noise reduction engineering.
