Interesting thought ... but would 1/4" glass would give you anywhere near
the same strength as 1/4" aluminum? What sorts of applications have you
done
and when would you not use them. I'm thinking glass backing plated would
be
fine where there is no pressure being applied?

You could use them in pretty much all places you would use aluminum backing
plates. You might make them a little thicker than comparable aluminum
thickness (say on the order of the bolt diameter x 0.4 as rule of thumb).
I would not use glass backing plates in areas where small dimensions are
important. Your last sentence doesn't make sense to me - why have a fitting
where no pressure could be applied?

Glass (especially G-10) backing plates are SOP on racing yachts.

Another plus to G-10 backers just occurred to me-
Metal (and g-10) backing plates are hard to taper at their edges, so they're
bound to have stress risers at their edges. With G-10, a little feather of bog
and another larger layer of glass will taper the stiffness out evenly into the
panel. Tidy, too.

G-10 pressure laminates (built correctly)are up to 40% stronger than 6061
tempered aluminum.

I've been buying G-10 from McMaster-Carr, where 1/4" G-10 is about $23/ft^2.
Anybody got a lower-cost source?

Make them yourself during laminating with scrap amounts of resin/cloth.
G-10 is nothing special, just consistent and convenient for a commercial
builder but a home builder can do well by just having precut pieces of cloth
to use on left over resin.
