and cured at elevated temperatures. Anyone know what I am talking
about or where I can buy this thing?

I am basically looking for a way to avoid having to hand make long
lengths of fiberglass tapes for noncritical applications. But it has
to cure fast at room temperature like any standard epoxy so the
premixed ones won't work.

Thanks!

Prepregs are literally pre-impregnated with catalyzed resin.
They are kept from hardening by being kept at low temperature.

It has nothing to do with pressure - certainty not from
something as flimsy as a squeegee.

Sounds like you need to hit the books.
There are LOTS of tehm.
Try Amazon?

I am very familiar with the standard prepregs and how to work with
them (as I indicated on the original post). But the type I am thinking
of is an unusual type. It has the resin and hardener separated by a
thin membrane inside the glass, and when you squeeze it hard the
membrane ruptures and mixes the two components *(I think the color
also changes to indicate proper mixing). If you have a reference or
vendor for this item, I would appreciate any info.- Hide quoted text -

I have seen what you are discussing in a clay like form but never in
an impregnated glass. The concept sounds great but I can't see how
you would ever achieve a good and consistant mixture.
