Water resistant sound absorbers with reduced thickness and excellent sound-absorption properties in the low and medium frequency range, that pass the fire tests (Federal Aviation Regulation FAR 25.853 and FAR 25.855) which are mandatory in many engineering areas, were produced through an eco-friendly electrospinning process. It is shown that the produced PVP/silica samples may have better sound absorption properties, in the lower frequency range, than materials, of the same thickness, that are usually used in both the civil and aerospace engineering fields. Preliminary results suggest that the mats have potential application for thermal insulation.

Abstract
Water resistant sound absorbers with reduced thickness and excellent sound-absorption properties in the low and medium frequency range, that pass the fire tests (Federal Aviation Regulation FAR 25.853 and FAR 25.855) which are mandatory in many engineering areas, were produced through an eco-friendly electrospinning process. It is shown that the produced PVP/silica samples may have better sound absorption properties, in the lower frequency range, than materials, of the same thickness, that are usually used in both the civil and aerospace engineering fields. Preliminary results suggest that the mats have potential application for thermal insulation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
