摘要：

To　take　full　advantage　of　the　excellent　properties　of　carbon　nanotube　(CNT),　a　3D　CNT-based　nanostructure　was　designed　theoretically　by　orderly　connecting　CNTs　with　different　diameters.　It　was　validated　by　the　first　principle　that　the　present　nanostructure　had　stability　with　a　minimum　energy　of　the　system.　Finally,　the　Young＇s　moduli　and　strength　of　the　3D　CNT-based　nanostructures　under　tension　and　compression　were　predicted　using　the　molecular　dynamics　(MD)　method.　The　results　show　the　moduli　and　strengths　of　the　3D　CNT-based　nanostructures　can　reach　185~260　GPa　and　67~97　GPa.　The　3D　CNT-based　nanostructures　are　more　stable　under　compression　for　the　existence　of　the　supporting　tube.　©,　2015,　Beijing　University　of　Technology.　All　right　reserved.
