A process for making a composite substrate with cover utilizes heated dies of a forming tool to deform and heat the substrate. The heated substrate is then placed in a marriage tool having a room temperature lower die for receiving the substrate, and a heated upper die. A cover material layer is placed over the substrate and the marriage tool is closed. The cover material includes a heat activatable adhesive and with the marriage tool closed, the heat from the upper die adheres the cover material layer to the substrate while the room temperature die cools the substrate. In this way, when the marriage tool is opened, the composite structure can be removed without deformation.
