ResumoMechanical characterization of a two-dimensional Thermal Energy Storage (TES) composite structure that combines the heat storage capability with structural functionality was carried out experimentally. Static and fatigue experiments were conducted for the composite structure under three-point bending at both room temperature and elevated temperature. An energy method model was developed to predict the mechanical behavior of the composite.
