Abstract
In the present letter, we consider homogeneous and isotropic noncommutative cosmological models induced by a symplectic formalism coupled to phantom perfect fluids and a cosmological constant. After computing the field equations, we solve them to find the scalar factor dynamics. We restrict our attention to expansive solutions, that may represent the present expansion of our Universe. Those solutions generate {\it big rip} singularities. We study how the parameters, of those models, modify the time it takes to the scalar factor expands from zero till infinity, at the {\it big rip}.
