I know that microwaves are sometimes used to cure epoxy but does
cured epoxy absorb microwaves? More practically put: can I use
epoxy to glue some parts of a double quad for 2.4GHz?

Your best source of information here will be the manufacturer.

Next best will be to put a test object (made of things that don't absorb
microwaves) glued with the epoxy in your microwave with a cup of water and
heat it until the water boils. If the test object isn't uncomfortably hot,
the epoxy probably is OK for use in your quad. Microwave ovens here in
the US seem to run around 2.45 GHz, which is fairly close to your working
frequency, so the test will be a fairly good indication.
