It won't withstand boiling water?

The epoxies used in homebuilts - cured at room temperature - generally
start to soften around 200 degrees F. It varies with the epoxy and
with what temperature any one part has been exposed to before - you
can post cure many epoxies by subjecting them to higher temperatures,
and get their transition temps up, by as much as 70 degrees F.

The epoxies used in the 787 are cured at much higher temperatures to
begin with.

But this can't be too difficult for Boeing to explain. All they have
to say is "our fiberglass is treated to handle as much heat as
aluminum" or something similar, if that is indeed true.
