Here's a nice article about the way that Lotus stick the Elise chassis
together from bits of aluminium - they use a specialised epoxy resin.

As it says for some reason the industry is very cagey about giving full
details of the types of epoxy used in different applications. The Lotus
glue is an odd one, a heat cured epoxy. That wouldn't work for large
aircraft. The Wings on most modern aircraft are bonded using an
epoxy-polysulphide adhesive (I think, but I'm not sure).
Apparently they still rivet each joint to stop a peel type failure.
Yes, called the "chicken rivet".
Fascinating article.
Most glues are good in shear, bad in peel..that's why tenoned joints are
used..
