I'm looking for an appropriate epoxy for the small samples that I'll use for impact testing. Thin infusion epoxy (600 cps, sometimes less) looks like it would work well: easy wet-out, will leave the layup and get into the bleeder reliably, etc. Can an epoxy be too thin for this purpose? Can it be so thin that not enough stays in the layup to transfer the loads between reinforcment fibers?I'd like to try out bagging against a mylar sheet for a smooth top surface (see what that costs in weight), but perhaps a very thin epoxy won't even fill the weave in a fully compressed layup.
Thoughts and tips welcome.
