+x dcfoster - 2/25/2019 11:30:55 PMIm having a similar issue, but its also leaving some of the epoxy on the mold surface. Ive added mesh to increase flow upon entry and created a resin break to slow down exiting epoxy into the catch pot. Also im using an infusion epoxy yet I keep getting dry patches. Im using a blue carbon/nylon cloth for the visible layer and then a +/- 45 biax for the underlayer. This is for a fuel door for an Acura. Ive never had this issue before, even with small parts but I keep getting it with this. Could it be since its winter that its too cold? I made sure to put my epoxy in front of a heat source to warm it up and noticed it gassed alot less when mixing, I also let it sit to degass for the 15min I usually wait to make sure the infusion molding is properly sealed and not leaking (the epoxy I use has a long pot life). Yet it only made less dry spots but still have them. Pics included.Original poster. sorry to thread jack, figured since you already have a thread open it just makes sense to keep all the 'dry fiber' issues in one thread.

I would guess it's related to the spray tack. Either too much or a kind that does not dissolve properly in epoxy.To the original poster - could you share a picture of the vacuum setup? Normally this kind of things can be solved with the right infusion setup...
