I am researching the most economical way for us to source carbon fiber pre-preg for our prototyping shop. I was wondering if there are any cross-compatibility issues I need to be aware of when it comes to laminating prepregs from multiple suppliers. Specifically, I want to cure UF3325 TCR™ RESIN from Composite Envisions with Easy Composites' XPreg XC110 Resin. Is there an easy way to tell if these epoxies are compatible?

Thanks,

Nathan

At the very least you need to consider pre-pregs with very similar cure profiles.  Significantly different cure profiles is asking for trouble as one part will cure before the other and hence delamination and weak inter laminar bonds are quite easy to see why they might happen.  Also with resin flowing at different temperatures, you may well get a poor surface finish.

Unless the manufacturer of a  pre-preg system has tested or designed it work with some other systems (can happen with surface layers for example) then you would need to do your own tests to see if it works properly.
