Abstract

A tool for manufacturing a sandwich composite material component is provided that includes a lower tool having a surface configured to receive materials for forming the sandwich composite material component. An upper tool is also provided that has a sealing edge and a cutting edge. The upper tool and the lower tool are configured to be separated to an open position and to be brought together to a closed position, the upper tool and the lower tool define a cavity when in the closed position. A process for forming a sandwich composite material component is also provided.

Claims (15)

1 . A tool for manufacturing a sandwich composite material component, the tool comprising:

a lower tool having a surface configured to receive materials for forming the sandwich composite material component; and

an upper tool having a sealing edge and a cutting edge;

wherein the upper tool and the lower tool are configured to be separated to an open position and to be brought together to a closed position, the upper tool and the lower tool defining a cavity when in the closed position; and,

wherein the sealing edge extends farther from the upper tool than the cutting edge extends from the upper tool such that the sealing edge is configured to contact the materials for forming the sandwich composite before the cutting edge, and the sealing edge and the cutting edge extend around the entire perimeter of the cavity.

2 . The tool of claim 1 wherein the surface configured to receive materials for forming the sandwich composite material is a planar surface.

3 . The tool of claim 1 wherein the surface configured to receive materials for forming the sandwich composite material includes a protective barrier.

4 . The tool of claim 1 wherein the lower tool includes at least one locator configured to indicate correct positioning of the materials for forming the sandwich composite material component relative to the surface of the lower tool.

5 . The tool of claim 1 wherein the cutting edge is configured to trim excess material from the materials for forming the sandwich composite material component.

6 . The tool of claim 1 wherein the upper tool and the lower tool apply a compressive force to the materials for forming the sandwich composite material component.

7 . The tool of claim 1 wherein the upper tool and the lower tool apply heat to the materials for forming the sandwich composite material component.

8 . The tool of claim 1 wherein the upper tool includes a shaped form configured to impart a shape to the materials for forming the sandwich composite material component.

9 . The tool of claim 1 further comprising at least one applicator configured to apply a substance to the materials for forming the sandwich composite material component.

10 . The tool of claim 1 further comprising at least one pin configured to be inserted into the cavity and through which a vacuum is applied to the materials for forming the sandwich composite material component inside the cavity.

11 . The tool of claim 1 further comprising at least one injector configured to be inserted into the cavity and through which a substance is injected into the materials for forming the sandwich composite material component inside the cavity.
