In this paper it is shown that a laminate composed of identical anisotropic layers, like for instance composite plies, cannot reach all the possible elastic states that are allowed by the classical elastic bounds on anisotropic constants. The analysis is carried on and facilitated by the use of particular tensor invariants, the so-called polar parameters.
