I am wanting to infuse a 5mm thick PVC foam sandwich and I am asking myself if having the foam grooved on one side only but also with drilled holes will work ok.

Foam down with the grooves against the mould/outer laminate and then a full surface flow medium on the inner skin side which has no grooves, flow medium outside the peel ply.




I hope this makes sense. ??

Anybody else infusing thin foam cores?

The foam I use is just drilled at about 50mm c/c each way (6mm core), I only have a couple of layers each side and not had an issue

I could test this out.

I am still concerned about the overall speed. Is it fast enough to get an area done. I am doing 3.2m2

Don't know, the largest I've infused is 1500x500
