Large panel infusion.

Here is my last infusion. 40"x30"x1.5" webbed rod foam core (square rods of foam, wrapped in glass web, and bonded top and bottom with scrim), and 0/90 layers of uni carbon.
Infused the middle first, till the resin hit the gap, which let the bottom flowfront to catch up. When it finally hit the edge disto. media, I let them infuse, as I clamped off the middle. Took only about 30min. VER thinned with about 10% styrene.
One tiny dryspot on the bottom, which will be recoated with VER and later tabletop casting resin for a nice finish due to the crappy table tops we have. Milled finish, with MANY scratches.

and what is this for? A table top?

Pretty cool expiratments you get to do. Got a question though.

Any concerns about the styrene not being able to off gas due to being in a closed environment?

Im thinking its gotta be similar to bagging acetone thinned epoxy. Tiny spheres of unevaporated trapped gas remain permanantly in the layup.

Yup. Had almost dumpstered core, and a roll of carbon that has no use in life.
Now they do
Thinking about going to Ikea and getting some sort of modular leg system. They got everything.

Interesting thought, but i think due to being in a vacuum, it automatically degases itself in the bag. I never degas my VER before infusing, because it does it automatically. You can see the gas bubbles in the flow front, then it stops a few inches in.
