The　paper　studied　the　varying　mode　of　shear　stress　in　the　connecting　zone　of　CFRP.　Using　epoxy　resin　(EP)　as　bond　material,　performance　of　specimens　with　different　connecting　length　of　CFRP　was　tested　to　obtain　the　conclusion.　CFRP-confined　concrete　column　was　tested　subsequently　to　verify　the　conclusion.　The　results　show　that:　(1)　The　binding　properties　of　modified　epoxy　resin　with　CFRP　is　good;　(2)　As　the　connecting　length　increased,　the　ultimate　tensile　strength　of　CFRP　increased　as　well　in　the　range　of　the　experiment　parameters;　(3)　Tensile　strength　of　CFRP　can　reach　the　ultimate　strength　when　the　connecting　length　is　90mm;(4)　The　connecting　length　of　90mm　of　CFRP　meet　the　reinforcement　requirements.
