Abstract：

In　the　present　work,a　novel　entangled　metallic　wire　material-polyurethane(EMWM-PU)composite　was　developed　through　the　vacuum　infiltration　method　with　the　entangled　metallic　wire　material　(EMWM)as　the　matrix　and　polyurethane　as　the　reinforcement.　By　comparing　the　quasistatic　compression　properties　of　EMWM　and　EMWM-PU　composites,it　was　found　that　the　composites　exhibited　excellent　energy　consumption　and　stiffness　properties　due　to　the　interfacial　friction.　The　pipeline　test　platform　was　built,and　the　vibration　acceleration　level　and　insertion　loss　were　used　as　evaluation　indexes.　In　addition,the　effects　of　EMWM　density,excitation　levels　and　preload　on　the　vibration　damping　performance　of　the　pipeline　were　studied　in　detail.　The　results　showed　that　the　EMWM-PU　composites　have　excellent　vibration　reduction　effect　in　the　frequency　band　of　5—1　000　Hz,and　the　smaller　of　the　matrix　density　and　the　larger　the　preload　during　installation,the　better　the　vibration　reduction　effect.　This　study　provides　effective　guidance　for　the　design　and　application　of　EMWM　composites.　©　2024　Cailiao　Daobaoshe/　Materials　Review.　All　rights　reserved.
