Ideal infusion with delay added:

[riff42]

I’ve been meaning to post some pics of a standard infusion method with peelply delay. In these photos, everything is straight forward, and I hope easy to understand. Distro media is smaller than the part, and covering the inlet. Peelply is bigger than needed, but shows you the delay area. This allows air to leave the part, and when infusing, it lowers the risk of sucking up resin, it also allows the microvoids in the tows to get saturated, and the resin to continue to flow, albeit slowly. Bagging shows pleats on the opposite side of the tubing. None are needed perpendicular to the tubes, since it’s a thin part. Bagging is also on the large side, I didn’t do this part. Peelply is also covering the spirals, so the edges don’t cut the bag.
Caul plate infusion is the same, except add a plate on top (same size, or slightly smaller than part), and don’t use any distro media (except maybe around the infusion side. I use peelply around the infusion and vent side, just covering the corners of the plate.

Enjoy.

Nice. Why does it look like you have two tubes in the resin bucket?
Since this is on the subject of infusions. What’s the highest CPS you have infused? I thought I read a post from you awhile ago about needing to heat the resin to a few hundred degrees just to get it to the right cps. The highest I’ve ever used was around 1000cps at room temp and it took 45min.

I did not do this infusion, but it looks like they used a short tube to mix the resin. That is done often around here, since our wood sticks don’t mix large batches well. And some people don’t KNOW we have wood sticks
I have no idea about the highest I have infused. The one epoxy which I think you are mentioning is 1000cps at 50c, and down to 300 at 70c. Geltime was 21min at 150c, so at that temp, it was much lower than 300.

This was the stuff…after the bucket was on its side for 20min.

Yummy Maple syrup! That’s the stuff I was talking about.
