Method and apparatus for producing a multipurpose panel with structural, functional, and energy absorbing features

A method of making a panel by depositing a first extrudate into a mold cavity and pressing the first extrudate with a mold core to form a skin layer. The skin layer is cooled inside the mold cavity. A core material is loaded in the mold cavity onto the skin layer. A second extrudate is deposited int...

Zusammenfassung:	A method of making a panel by depositing a first extrudate into a mold cavity and pressing the first extrudate with a mold core to form a skin layer. The skin layer is cooled inside the mold cavity. A core material is loaded in the mold cavity onto the skin layer. A second extrudate is deposited into the mold cavity and onto the core. The second extrudate forms a structure layer. The mold core is pressed against the structure layer so that the structure layer forms around the core. The pressure of the mold core against the structure layer also presses the core into the skin layer. The structure layer and the skin layer cool while the mold core is pressed against the structure layer and the core material and the skin layer to form a panel. The panel is removed from the mold cavity.
