Wow infusing panels that complex and that size good work!!! Looks like a near perfect finished part.
How many infusion inlet and outlets did you have and what size?
Also are you using a pressurized resin system or just the good old bucket?
I have tried a few times to infuse panels like that but have not had the best of outcomes, nothing like the quality of your panels. I have even had dry areas the resin has not reached.
When you lay in the dry carbon are you using some tack spray of some sort. I have been using AirTac as recommended by my supplier but I am not sure about it. I am thinking it might be stopping the carbon and proceeding layers from forming into the corners nicely.
Maybe you have some photos of the panels being infused?? :-)
Who are you getting all you infusion material from?
Sorry for all the questions but when I see work that good I have to ask questions :-)

I won't lie, they are complex parts and they are not simple to make... Lots of time.
Not having breaches and getting the resin everywhere is quite hard and takes planning, I put in loads of extra resin entry points at places I'm worried about or far from what I consider the natural flow and to date I have only had one 2 dry point issues and I solved them by adding resin entry point during infusion. Not ideal but doable.
Lots of pictures on my photobucket account, here is one of the tub being infused... I envelope bagged it, the bag was 5m long by 4m wide :-)

Is that the top of a vacume tank with the gauge on it, that i can see in the backgoundNot having breaches and getting the resin everywhere is quite hard and takes planning, I put in loads of extra resin entry points at places I'm worried about or far from what I consider the natural flow and to date I have only had one 2 dry point issues and I solved them by adding resin entry point during infusion.

how much vacume are you able to pull, did you have any issues with the core material collapsing?
fantastic work. i too would love to see some more photos of the vacum tanks, pumps, resin pots ect.

One trick i would say helps with vacuum infusion, is to pull the entire bagged part down to a vacuum BEFORE you allow the resin to flow into it. This ensures that the vast majority of the trapped air is removed before the resin flows in to replace it, and helps avoid dry corners etc. The easy way to do this is use those cheap brake pipe clamps to simple crush the plastic tubes feeding the resin into the mould. Opening / closing them helps control the flow of resin into the part as well.
