As others have said sucking and see
Most will work together no problem
At the moment am doing some f1 pod fronts
6 different materials (1 glass 5 carbon)
Woven an ud 
4 different weaves
3 different resin systems
Works fine

Very interesting. Why are you having to use different resin systems (apart from because of glass and carbon)?

Most teams can't get all their materials from one supplier

That an young composite designers like to appear really clever an inventive an make it as complicated as possible
Lot to be said for KISS
but no we have a part with flat tow,u/d,glass,satin weave an 2x2 twill all for a bit of bodywork !

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.

You learn something new every day :-) I can only base my comments on my own experiences and agree with you that testing is the only way to find out. We need to ask the OP why he needs to mix epoxies? Probably best not to as even testing, unless under long term laboratory conditions, will tell you the actual bond strength and longevity of the bond. My mix was on a non critical car interior panel.

Where the pod goes there is a transponderCarbon mucks up the signal so it has a little glass window thou you would never know once its painted
