On the Mechanical Response of a Random Chopped Fiber Mat/Polymeric Resin Composite: Data and Model

This article presents data on the creep response of a polymeric composite that is a candidate material for automotive applications. The above data established the basis for the mechanical characterization of material's response over a wide range of stresses and temperatures, as well as under cyclic tensile loading. A constitutive model based upon fundamental principles of irreversible thermodynamics and continuum mechanics was employed to encompass the above mentioned database and to predict the response under more complex inputs. These latter tests verified the validity of the model.
