Carbon　nanotube　fiber　(CNT　fiber)　with　excellent　electrical　and　mechanical　properties,　as　well　as　stable　thermal　and　chemical　properties　has　great　potential　application　in　areas　such　as　ultra-fine　wires,　ultra-light　cables,　sensors,　composite　materials,　energy　conversion　and　electro-actuation.　In　this　paper,　the　static　and　dynamic　mechanical　properties　of　impregnated　CNT　fiber　were　studied　through　single　and　cyclic　tensile　experiments　and　continuous　dynamic　analysis　(CDA).The　dynamic　properties　of　impregnated　CNT　fiber　such　as　storage　and　loss　modulus　was　obtained.　In　addition,　the　storage　modulus　and　loss　modulus　of　impregnated　CNT　fiber　increases　with　the　increase　of　loading　frequency.　The　research　work　in　this　paper　has　an　important　reference　value　for　the　engineering　applications　of　impregnated　CNT　fiber　in　the　fields　of　sensors　and　composites.　©　Published　under　licence　by　IOP　Publishing　Ltd.
