System and method for manufacturing panels for use in wind turbine rotor blade components
A system for manufacturing a panel includes a forming assembly having opposing press plates and at least one platen assembly arranged between the opposing press plates. The platen assembly includes first and second platens connected together via at least one elastic deformable member. Further, the forming assembly is operable in a heating mode and a cooling mode. Moreover, the first platen is maintained at a predetermined temperature range during each of the heating and cooling modes. During the heating mode, the elastic deformable member(s) is compressed such that the first and second platens contact each other. As such, one or more layers of material to be consolidated are held by the forming assembly as the forming assembly applies heat and pressure to the layer(s), thereby consolidating the panel.
1. A system for manufacturing a panel, the system comprising:
a forming assembly comprising opposing press plates and at least one platen assembly arranged between the opposing press plates, the at least one platen assembly comprising first and second platens connected together via at least one elastic deformable member, the forming assembly operable in a heating mode and a cooling mode, the first platen being maintained at a predetermined temperature range during each of the heating and cooling modes;
wherein, during the heating mode, the at least one elastic deformable member is compressed such that the first and second platens contact each other, and wherein one or more layers of material to be consolidated is held by the forming assembly as the forming assembly applies heat and pressure to the one or more layers of material to be consolidated, thereby consolidating the panel;
the opposing press plates having an entry end where the one or more layers of material enter between the opposing press plates and an exit end where the consolidated layers of material exit from between the opposing press plates in a direction of travel of the one or more layers of material through the forming assembly; and
wherein the second platen comprises, at least, a first portion and a second portion, the second portion extending outside of the opposing press plates adjacent the exit end of the opposing press plates, the second portion cooled independently of the first portion.
2. The system of claim 1 , wherein, during the cooling mode, the at least one elastic deformable member is relaxed such that the first and second platens are spaced apart from each other via an air gap.
3. The system of claim 2 , wherein the air gap ranges from about 1 millimeters (mm) to about 25 mm.
4. The system of claim 2 , wherein the second platen comprises a plurality of channels for circulating a cooling fluid therethrough during the cooling mode, wherein circulating the cooling fluid through the channels lowers a temperature of the second platen.
5. The system of claim 1 , wherein the second platen further comprises a thermal barrier between the first and second regions.
6. The system of claim 1 , wherein the forming assembly further comprises a plurality of elastic deformable members connected between the first and second platens, each of the plurality of elastic deformable members being recessed within at least one of the first and second platens.
7. The system of claim 1 , further comprises first and second caul plates, wherein the at least one platen assembly comprises a first platen assembly arranged above the first and second caul plates and a second platen assembly arranged below the first and second caul plates, the first and second platen assemblies each comprising the first and second platens.
8. The system of claim 7 , wherein the first and second caul plates are continuous belts that rotate through the heating and cooling assemblies.
9. The system of claim 7 , wherein the second platens comprise rounded edges.
10. The system of claim 7 , wherein the opposing press plates are integral with the first platens of the first and second platen assemblies.
11. The system of claim 1 , further comprising one or more spacers for controlling a final thickness of the panel, the one or more spacers positioned within the forming assembly.
12. The system of claim 7 , further comprising a spool, wherein, upon cooling, the panel is separated from the first and second caul plates and spooled onto the spool.
