Hi.

Which light weight flexible core material(nomex, 3d core pet, soric, etc) would you recommend(3-5mm) for ooa low temperature prepreg part(light weight monocoque)? I plan to use 2/2 twill 3K carbonan for outer layers + 6K inner layer and a core inside.
Would the core material require any adhesives or is it as simple as laying it on top of inner layer and proceed with second inner layer, outer layer then bagging and vacuum curing the whole thing at 1 shot?

Mtm28b is core bondable., there are others
That's the only one I can think of off the top of my head and that is an old school resin bath an roller pre preg.
All the new OOA systems are hot rolled so all your resin is as far from your core as it's possible to get
Make some samples and do some peel tests.
You'll soon see how well things stick without film glue.!
Seen LOTS of stuff on YouTube but it's mostly from idiots who haven't got a clue
For core you really want a supported film glue rather than in supported
Thin nomex you will get away with 150gm
Not that heavy
Thanks for the input. It is a steep leraning curve!
Any good sources for film glue that is not too expensive and works with nomex?
