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?
