Sound Absorption Property of Hydrogenated Carboxyl Nitrile Rubber/Seven Hole Polyester Fiber Composites

Abstract:

A series of HXNBR/SHPF composites were fabricated and sound absorption property was investigated. The results showed that with increasing of SHPF proportion the sound absorption coefficient was raised. The composite sound absorption coefficient with thickness of 1mm is 0.385, 0.438 and 0.535 at frequency 2500 Hz when the SHPF proportion is 10%, 20%, 30%, respectively. The HXNBR/SHPF composite sound absorption property could also improved by increasing the composite thickness with constant fiber proportion. The composite with thickness of 2mm and SHPF proportion is 10%, 20%, respectively. The sound absorption coefficient increased from 0.385 to 0.427 and 0.438 to 0.475 at frequency 2500Hz, respectively. The mechanical property also improved with increasing of SHPF proportion. So, the HXNBR/SHHPF composite has potential practical application value.
