Sound insulation of honeycomb weave fabric reinforced polyvinyl chloride composite
2011
In order to study the acoustic insulation property of honeycomb weave fabric/PVC composite material,a honeycomb weave fabric with the same surface density but different repetitions of weave was woven on an automatic sample loom using 58.3 tex×2 cotton yarn as warp and weft.Honeycomb weave fabric/PVC composite material was fabricated using the halloysite nanotubes(HNTs) filled polyvinyl chloride(PVC) as substrate,and then a sandwich structure composite was made with the honeycomb weave fabric/PVC composite as core material.The sound insulation quality of prepared samples was tested by acoustic analyzer of two-channel.The results showed that repetitions of weave have great influence on the sound insulation effect of honeycomb weave fabric.When the repetitions of weave are 6,the composite material displays good sound insulation.In the case of sandwich composite material with the honeycomb weave fabric/PVC composite as core material,it exhibits good sound insulation to low frequency when the repetitions of weave are 6,and its good sound insulation to high frequency is found when the repetitions of weave are 14.
