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

Not all epoxies are the same and they dont all play nicely together. Before the X-Preg system, I tested co-curing several brands of pre-preg together in an attempt to find a unidirectional material I could use with EasyPreg. Not one of them worked. They all cured fine, but they all delaminated from each other. You could peel the various brands apart like they had release film between them.

There's no hard and fast rule for this sort of thing, but it is always safer to assume that they will not be compatible and do some tests. I highly doubt the manufacturers will know what other systems theirs may be compatible with, theres just too many variables to know that - the reply will always be "we dont know, you'll need to test it yourself". You may get lucky and find a combination that works, but nobody is going to be able to tell you for sure - you need to test it all yourself and be comfortable with the results you get.

had the exact same experience in my shop...
