Active Fiber-reinforced Composites are artificial bodies consisting of one or more layers of parallel ceramic fibers embedded in a polymer matrix. In this paper we propose a mathematical model for their constitutive response by importing certain concepts from the modeling of fibrous living tissues and by regarding an AFC as a special piezoelectric material body whose stored energy is a weighted sum of the stored energies of fibers and matrix.
