copper head gaskets

hi all just trying to find out some things, were can i get copper sheets from to make a gasket, and what do they use in the centre of a double copper gasket is it some kind of foam, also how is the gasket stuck to the foam, any help would be most appreciated as im at a bit of a dead end her at the minute

isnt the head gasket made like a sandwich? eg copper what evers in the middle the copper, then punched out?

Cheers Steve

quote from Wiki
Composite -- an older technology. Typically these are made from asbestos or graphite but are more prone to blowouts than newer gaskets. Asbestos gaskets are becoming increasingly rare due to health concerns.[2]

it was a layer of copper at the top and one at the bottom, but something black in the middle ??????? ideas

if it was black/grey i would say graphite, dont go snorting it either way

hmm dark blue/balck could be Asbestos, whats it for?

but it looked like foam, it was brand new recently so would not have been asbestose, anymore ideas

ah its new should have said

modern stuff is compressive gasket material, the copper helps to keep it all together under the duress of its duties, the material is a modern composite, probably containing things like silica/silicon (glass) and other high temperature fibres.
