I want to use 2mm Lantor Soric for building a model boat and I want to place the infusion spiral in the middle of the part. Do I need to cut the Lantor Soric in halves just below the infusion spiral or will the resin flow through it?
On all videos I have seen, the resin starts flowing from the edge, but I am not sure if I can put the spiral on top.

Resin flows through Soric very well so you will not need to cut through it at all.

I read in the description How to use Soric SF: https://www.easycomposites.co.uk/lantor-soric-sfAs soon as the resin reaches the edge of the laminate it will infuse quickly through the canals in the Soric SF and through the rest of the laminate. The rest of the infusion is undertaken just as normal.
I think it says that the resin is better flowing through the canals than through the surface of the Soric, so I am wondering whether it's advised to cut it along the infusion spiral. Otherwise, the resin would reach the edge of the Soric after the whole part is infused, because the infusion spiral will be placed in the middle.

The canals go right to the surface of the Soric as well as all along it, so there is no need to cut the Soric. As long as the resin has a path to flow, either from the end of the Soric or down through the middle then along, it doesn't matter. Once the resin gets to the Soric, it will flow plenty well enough.

Thanks! One more question. I see I don't need to use peel ply or infusion mesh with Soric, but I am worried that the infusion spiral would stick to the laminate, because it will be filled with hardened epoxy that has been flowing through the gaps. Does this happen? Should I separate the spiral with peel ply?

+xThanks! One more question.

Does this happen? Should I separate the spiral with peel ply? Yes, put peel ply or release film under the spiral. You only don't need to use it when you aren't putting anything directly on top of the laminate, ie. flow mesh. If you've got any consumables that you want to remove after the infusion then you need to use a release film or peel ply.

If the part is larger, I would not rely on the flow propertys of the soric. During my own experiments I didn't see any flow advantage compared to the same laminate without soric. A guy named Matthieu libeert made a YouTube video about that, backing my results. He basicly failed an feet long infusion, just relying on the flow propertys of soric

Also, peel ply on the whole part would be an good idea, as long as you can't put down the vacuum bag without pleats. The resin will flow in every little corner, and will leave your part with a thousand "resin razor edges" on the back. I have some nice little scars from this on my fingers.
I do a lot of infusions, and a good amount of the with soric, but I allways use peel ply and flow mesh all over the part.

A guy named Matthieu libeert made a YouTube video about that, backing my results. He basicly failed an feet long infusion, just relying on the flow propertys of soric An important point to make about Mat's infusion is that he did not have the resin inlet on top of the Soric, he had it in front of the Soric with no flow media. I'm a big fan of Mat's, I love his videos and he makes some great posts on here. But he made some mistakes in that Soric infusion that led to the failure, it wasn't the Soric that caused the problems. I use Soric and 3D PET Core as flow media all the time, and have done infusions as large as 1 piece bodywork for a GTO Monaro door slammer (so roughly 3m x 1.5m) without any flow media. You just need to be aware that it does flow a bit slower than green infusion mesh, so you need to account for this in your feed setup. If possible, it's always better to infuse from the middle of the part out to the edges, rather than across the distance of the part. If you aren't going from the middle or directly on top of the Soric, then you do need flow mesh on the edges of the part to facilitate resin flow into the Soric. If you are concerned about your pot life, then you need to mix smaller batches rather than trying to do it all in one hit.

How long did it take you for this infusion?
I disagree, that it was mat's fault. He shows, that the inlet was that resin rich, he could easily lift the bag. So the soric obviously had more than enough resin to feed from. Still, the flow front was almost frozen. And my results totally back that up. Pet core is a different story. The flow channels are wider and far more stable. Especially for the thicker ones. Still, no comparison to a flow mesh.
