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

Where the "window" goes there is a 60mm circle of 200gm carbon that has a 30mm circle cut of its centre.
That hole is then covered with 2 plies 100g plain weave glass circles 50mm dia at 90+45
Part is a two stage cure so its then covered with pre preg peel ply
90psi cook
When you do the 2nd stage you put another carbon circle with the centre cut out in the same spot as the first
