Environmental behavior of reinforced polyester was studied by stress relaxation. Relaxation failure of polyester matrix and fiberglass degradation appear dramatically at short time after exposure to acid and alkali electrolytes. The relaxation spectrum is thus influenced by environmental action. Indeed, the stress relaxation modulus is a sensitive characterization of environmental effects.
