- W2392413622 abstract "A series of elastomer composites were prepared with chlorinated polyethylene(CPE) as the substrate and seven-hole hollow polyester fibers(SHPF) as reinforcing material.The acoustical absorption property of the samples was studied.The results showed that CPE/SHPF elastomer composites have preferable acoustical absorption property at medium frequency and acoustical absorption coefficient of the samples markedly increased with increasing of the proportion of fibers.Acoustical absorption coefficient of CPE/SHPF composites with(1 mm) thickness is 0.364 in(2 500 Hz) frequency when the proportion in mass of CPE/SHPF is 100/25.The dynamic viscoelasticity of CPE/ SHPF was measured in order to analyze the acoustical absorption mechanism of the composites.It was found that the acoustical absorption is inversely related with their viscoelasticity.This is abnormal,indicating that there are some other factors that influence acoustical absorption of CPE/ SHPF.The mechanical properties of the composites were also tested.The mechanical properties of the composites improved significantly with increasing of fibers.As an acoustical absorption material,CPE/ SHPF composites have potential applications in engineering field." @default.
