Shimming of Metal Assemblies and Fatigue


Please click the source URL above to read the entire web page. Posted below is a snippet of the conversation.

I am looking for the help on choosing the shim material for the Aluminum (mainly 7000 and 2000 series).
Looked back on the previous programs 2000 aluminum sheets are used with the T3 heat treated.
Thinking over using GFRP shim on this assemblies, but strength and the Galvanic corrosion will not be there.
