Abstract
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.
