Abstract

A system for manufacturing a panel includes a support frame, a first caul plate arranged atop the support frame, a second caul plate arranged atop the first caul plate, and a heating assembly having a housing defining an inlet and an outlet. The housing includes one or more heaters. The heater(s) is configured to generate heat and the housing is configured to generate a first pressurized gas film. Thus, one or more layers of material to be consolidated may be placed between the first and second caul plates and drawn through the heating assembly as the heating assembly applies pressure to the one or more layers of material to be consolidated via the first pressurized gas film in combination with applying the heat via the one or more heaters, thereby consolidating the panel.

First claim

What is claimed is:

1. A system for manufacturing a panel, the system comprising:
a support frame;
a first caul plate arranged atop the support frame;
a second caul plate arranged atop the first caul plate;
a heating assembly comprising a housing defining an inlet and an outlet, the housing comprising one or more heaters, the one or more heaters configured to generate heat, the housing configured to generate a first pressurized gas film;
wherein one or more layers of material to be consolidated is placed between the first and second caul plates and drawn through the heating assembly as the heating assembly applies pressure to the one or more layers of material to be consolidated via the first pressurized gas film in combination with applying heat via the one or more heaters, thereby consolidating the panel; and
wherein the first and second caul plates are hinged on one side thereof to facilitate removal of the panel or reinserting one or more additional layers of material.

2. The system of claim 1 , further comprising a cooling assembly consecutively aligned with the heating assembly for solidifying the panel.

3. The system of claim 2 , wherein the cooling assembly is configured to apply a second pressurized gas film directly against the first and second caul plates while a chilled air stream is circulated in the cooling assembly.

4. The system of claim 2 , wherein the one or more heaters comprise at least one of radiant heaters or lasers.

5. The system of claim 2 , wherein the first and second caul plates are continuous belts that rotate through the heating and cooling assemblies to allow for a continuous process.

6. The system of claim 1 , wherein the heating assembly further comprises at least one optical window arranged adjacent to the one or more heaters, the heat from the one or more heaters passing through the at least one optical window and heating the one or more layers of material to be consolidated.

7. The system of claim 1 , wherein the one or more heaters further comprises a plurality of first heaters and a plurality of second heaters, the plurality of first heaters arranged below the first caul plate, the plurality of second heaters arranged above the second caul plate.

8. The system of claim 1 , wherein the heating assembly further comprises one or more sealing members between the housing and the first and second caul plates, the one or more sealing members providing a sealed environment that maintains a desired pressure of the first pressurized gas film against the first and second caul plates.

9. The system of claim 8 , wherein the one or more sealing members comprise a first sealing ring and a second sealing ring between the housing and the first and second caul plates.

10. The system of claim 8 , wherein the one or more sealing members comprise variable height seals, wherein the one or more layers of material to be consolidated further comprises one or more fiber and/or resin layers having a variable thickness, the variable height seals accommodating the variable thickness.

11. The system of claim 1 , further comprising a spool, wherein, upon cooling, the panel is separated from the first and second caul plates and spooled onto the spool.

12. The system of claim 1 , wherein the first and second caul plates are constructed of at least one of steel or titanium.

13. The system of claim 1 , wherein the support frame further comprises a plurality of rollers arranged adjacent to the inlet and/or the outlet of the housing of the heating assembly for assisting with drawing the one or more layers of material to be consolidated into and out of the heating assembly.

14. A system for manufacturing a panel, the system comprising:
a support frame;
a first caul plate arranged atop the support frame;
a second caul plate arranged atop the first caul plate;
a heating assembly comprising a housing defining an inlet and an outlet, the housing comprising one or more heaters, the one or more heaters configured to generate heat, the housing configured to generate a first pressurized gas film;
wherein one or more layers of material to be consolidated is placed between the first and second caul plates and drawn through the heating assembly as the heating assembly applies pressure to the one or more layers of material to be consolidated via the first pressurized gas film in combination with applying heat via the one or more heaters, thereby consolidating the panel; and
wherein at least one of the first caul plate or the second caul plate further comprises one or more stiffening ribs to enable handling thereof.

15. The system of claim 14 , wherein the one or more stiffening ribs are positioned outside of the heating.
