Sheet molding compound with cores
First Claim
1. A component made of at least one thermoformable material, comprising:
- a first structural layer made of a first material;
a spatial support layer made of a second material; and
a third structural layer made of said first material, said spatial support layer being disposed between said first structural layer and said third structural layer;
wherein said first structural layer, said spatial layer, and said third structural layer are placed into a mold, and said mold his heated such that said first structural layer and said third structural layer are chemically bonded to said spatial support layer.

Abstract
A component made of at least one thermoformable material, having a first layer made of a first material, a second layer made of a second material, and a third layer made of the first material. The three layers form a sheet, which is formed to various shapes, depending upon the part that is to be created. The sheet may be formed to produce the bumper of an automobile, a door panel for an automobile, a flotation device, such as a pontoon for a pontoon boat, or the like. The first and third layers are SMC, and the second layer, or “core,” is disposed between the first and third layers, allowing the strength of the first and third layers to be used more efficiently, compared to a sheet having only the first and third layers, and no core.

10. A method for making a component of at least one thermoformable material, comprising the steps of:
-
providing a first layer made of a first pre-impregnated material; providing a second layer made of a polymer material; providing a third layer made of said first pre-impregnated material; placing said first layer, said second layer, and said third layer into a mold such that said second layer is disposed between said first layer and said third layer to form a sheet; and curing said sheet in said mold by heating said mold to a desired cure temperature such that said first layer is bonded to said second layer, and said third layer is bonded to said second layer. - View Dependent Claims (11, 12, 13, 14, 15)

16. A wind blade made of at least one thermoformable material, comprising:
-
a top structural layer made of a sheet molding compound; a middle support layer made of a polymer material, said middle support layer having a first side and a second side; and a bottom structural layer made of said sheet molding compound; wherein said top structural layer is bonded to first side of middle support layer, and said bottom structural layer is bonded to said second side of said middle support layer, forming a sheet. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)
