Abstract

Honeycomb sandwich sound absorbers with microperforated panels (MPPs) as face sheets are widely employed in modern noise-reduction applications, particularly in the transportation and construction industries. An ultralight sound-absorbing honeycomb sandwich composite structure was developed, featuring structural skins of carbon fibre triaxial weave fabrics, adhesive films and polyester plain weave or nonwoven textiles. The normal incidence sound absorption coefficients of the resulting hybrid specimens were measured by impedance tube. The sound absorber achieved maximum noise reduction coefficients of 0.469, 0.637, and 0.670 for honeycomb heights of 20 mm, 40 mm, and double-layer 40 mm, respectively. This sound absorber demonstrates lightweight, high-efficiency, and relatively straightforward processing properties.

期刊介绍： The past few decades have seen outstanding advances in the use of composite materials in structural applications. There can be little doubt that, within engineering circles, composites have revolutionised traditional design concepts and made possible an unparalleled range of new and exciting possibilities as viable materials for construction. Composite Structures, an International Journal, disseminates knowledge between users, manufacturers, designers and researchers involved in structures or structural components manufactured using composite materials. The journal publishes papers which contribute to knowledge in the use of composite materials in engineering structures. Papers deal with design, research and development studies, experimental investigations, theoretical analysis and fabrication techniques relevant to the application of composites in load-bearing components for assemblies, ranging from individual components such as plates and shells to complete composite structures.
