Hi Arsouille,
That really is getting to be a very high quality looking product. I think yours are the first photos that I've seen of an infusion using the coloured fabric and I'm amazed how great the weave looks. The coloured fabrics (a bit like carbon/kevlar hybrids) usually show weave distortion much more obviously but the weave looks incredible. Great work putting that in so neat. I guess being a fairly flat shape helps a lot with that.
I'm still slightly puzzled by the air bubbles. They really are looking *tiny* now. Do they exist only at one side of the infusion (I can see that they're mainly at the very edge and in the main part they're past the 'trim line' but are they ocurring mainly at the vacuum end of the project? - If so then it might be (in your case) worth purging considerably more resin through. That is to say leave both the vacuum line and the resin line open quite a while after the resin has reached the vacuum line at the other side. If it's the resin at the 'front' of the advance that's harbouring the bubbles then purging it through (into the catch-pot or at least the vac line) might get rid of the problem. Once you've purged through in the manner you'll need to clamp of the resin line and then let the vac line pull down for a little longer to get some of the excess resin out of the laminate.
I hope this helps but the problem still must be being caused by something else that I'd love to get to the bottom of for you allthough it seems to be escaping all of us at the moment. Infusion projects that we do at EC (and Carbon Mods) really don't display any air bubbles like this so it certainly can be done!
All the best, Matt
