Are prepregs from different suppliers cross-compatible?

n Group: Forum Members Posts: 8, Visits: 145	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

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 ! Oh, yes, I live by KISS whenever possible. Why the glass, as this has different characteristics to carbon which some say are incompatible when subjected to high stresses.

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
