A method for joining two components includes positioning a thermoplastic polymer portion of a first component adjacent a thermoplastic polymer portion of a second component such that the first and second portions form an interface. At least one of the portions includes a microstructure having a plurality of closed cells, each cell containing a void and each cell having a maximum dimension extending across the void. The method also includes exerting pressure on the thermoplastic polymer portions to form a bond at the interface that holds the portions together. The plurality of closed cells, and especially those adjacent the surface of the thermoplastic polymer portion that form the interface, help isolate thermally and/or chemically the surface from the remainder of the portion.

1. A method for joining two components, the method comprising: positioning a thermoplastic polymer portion of a first component adjacent a thermoplastic polymer portion of a second component such that the first and second portions form an interface, wherein at least one of the portions includes a microstructure having a plurality of closed cells, each cell containing a void and each cell having a maximum dimension extending across the void within the cell that ranges between 1 micrometer and 200 micrometers long and wherein a plurality of the cells has a temperature equal to ambient temperature and includes gas in their respective voids in an amount sufficient to exert pressure on the microstructure; andafter positioning the polymer portion, exerting pressure on the exterior of the thermoplastic polymer portions to form a bond at the interface that holds the portions together, wherein the positioning and exerting the pressure occurs before the gas in the voids equalizes with the surrounding environment such that the pressure from the gas in the voids helps the microstructure resist the pressure exerted on the thermoplastic polymer portions. 2. The method of claim 1 wherein the plurality of closed cells each has a maximum dimension that ranges between 1 micrometer and 50 micrometers. 3. The method of claim 1 wherein at least one of the thermoplastic polymer portions includes a skin having a surface that defines an exterior surface of the portion and that forms the interface with the other thermoplastic polymer portion. 4. The method of claim 1 wherein the at least one thermoplastic polymer portion that includes the microstructure that has a plurality of closed cells, also includes a skin having a surface that defines an exterior surface of the portion and that forms the interface with the other thermoplastic polymer portion. 5. The method of claim 1 wherein the thermoplastic polymer portion of the first component and the thermoplastic polymer portion of the second component each includes: a microstructure having a plurality of closed cells, each cell containing a void and each cell having a maximum dimension extending across the void within the cell that ranges between 1 micrometer and 200 micrometers long, anda skin having a surface that defines an exterior surface of the thermoplastic polymer portion and that forms the interface with the surface of the other thermoplastic polymer portion's skin. 6.

The method of claim 1 wherein the pressure exerted on the thermoplastic polymer portions cause the portions to fuse at the interface. 9. The method of claim 1 further comprising heating a surface of at least one of the thermoplastic polymer portions, which forms the interface, to a temperature close to the surface's melting temperature, without causing a remainder of the portion to melt, before exerting pressure on the thermoplastic polymer portion. 10.

The method of claim 10 further comprising cooling the interface to solidify the bond. 12. A method for making a panel, the method comprising: positioning a first thermoplastic polymer sheet adjacent a second thermoplastic polymer sheet such that the first and second sheets form an interface, wherein at least one of the sheets includes a microstructure having a plurality of closed cells, each cell containing a void and each cell having a maximum dimension extending across the void within the cell that ranges between 1 micrometer and 200 micrometers long, andwherein a plurality of cells has a temperature equal to ambient temperature and includes gas in their respective voids in an amount sufficient to exert pressure on the microstructure; andafter positioning the thermoplastic polymer sheets, exerting the pressure on the thermoplastic polymer sheets to form a bond at the interface that holds the sheets together, wherein the positioning and exerting the pressure occurs before the gas in the voids equalizes with the surrounding environment such that the pressure from the gas in the voids resists the pressure exerted on the thermoplastic polymer sheets. 13. The method of claim 12 wherein the first thermoplastic polymer sheet and the second thermoplastic polymer sheet each includes: a microstructure having a plurality of closed cells, each cell containing a void and each cell having a maximum dimension extending across the void within the cell that ranges between 1 micrometer and 200 micrometers long, anda skin having a surface that defines an exterior surface of the thermoplastic polymer sheet and that forms the interface with the surface of the other thermoplastic polymer sheet's skin. 14. The method of claim 12 wherein while pressure is exerted on the thermoplastic polymer sheets to form a bond at the interface, the pressure inside each cell is equal to or greater than the pressure exerted on the thermoplastic polymer sheets. 15. The method of claim 12: wherein the first thermoplastic polymer sheet and the second thermoplastic polymer sheet each includes:a microstructure having a plurality of closed cells, each cell containing a void and each cell having a maximum dimension extending across the void within the cell that ranges between 1 micrometer and 10 micrometers long, anda skin having a surface that defines an exterior surface of the thermoplastic polymer sheet and that forms the interface with the surface of the other thermoplastic polymer sheet's skin; andfurther comprising heating each surface to a temperature close to the thermoplastic polymer's melting temperature, without causing a remainder of first thermoplastic polymer sheet and a remainder of the second thermoplastic polymer sheet to melt, to help each skin coalesce with the other to form the bond at the interface. 16. The method of claim 15 further comprising cooling the interface to solidify the bond. 17. The method of claim 12 wherein the pressure exerted on the thermoplastic polymer sheets cause the sheets to fuse at the interface. 18. The method of claim 12 further comprising: positioning a third thermoplastic polymer sheet adjacent the second thermoplastic polymer sheet such that the third and second sheets form a second interface, and wherein the second sheet lies between the first and third thermoplastic polymer sheets; andexerting pressure on the third and first thermoplastic polymer sheets to form a bond at the second interface that holds the sheets together. 19.
