In　order　to　know　the　influence　of　factors　including　ratio　and　temperature　on　the　effective　mechanical　properties　of　CNT/SMP　composite,　theoretical　and　numerical　methods　are　adopted　to　study　the　changes　of　the　composite　in　the　aspects　of　the　stiffness　coefficients,　axial　orientation　modulus　and　landscape　orientation　modulus.　It　is　supposed　that　the　inclusion　CNT　is　the　transversely　isotropic　material.　SMP　is　described　in　a　thermodynamics　equation.　The　effective　property　of　the　composite　is　deduced　by　the　method　of　Mori-Tanaka.　It　is　shown　that　the　main　stiffness　coefficients　increase　along　with　the　increasing　of　ratio　and　the　axial　orientation　modulus　increases　more　rapidly.　When　the　ratio　is　a　constant,　the　landscape　orientation　modulus　is　lower　remarkably　when　the　temperature　is　higher,　but　the　axial　orientation　modulus　is　nearly　invariable.
