do you think it is possible to build a surfboard with the infusion on both sides and a eps core inside?

The eps foams usually used for surfboards are not strong enough to withstand a full vacuum.
I'm not saying it's impossible, but certainly complicated and won't give you really an advantage.

     Sorry, but vacuum bagging doesn't apply any pressure to a solid material. In principle, the bagging film applies just the same pressure to the foam, that the atmosphere would do without the bagging.....

             Yes obviously it doesn't on a solid. The problem is though, that the EPS foam has not perfect closed cells, is inhomogeneous and degasses, so it will crush your foam.

     I infused samples with cheap eps in the past. But as it's so cheap I bagged a small sample of foam yesterday. 7mm strong. Sunk in 1/10th mm right away as I applied vacuum and then stayed there for...

             you got me curious there and i just ran the same test as well and the foam was completely fine. I was sure i tested that once years ago and crumbled the foam, but i do not know what i did back then.....

                 I crushed a windsurf board many years ago. It seemed fine at first but then I left it for some hours and when I came back the whole deck had collapsed. I think maybe if you had a harder foam and/or.....

                     let the pump run after that statement and now after a couple of hours the core is quite a bit crumbled. certainly not usable for anything really. So i revise my opinion again and stand by what i said...

     My foam is still exactly as before. Pressure is still at 8 mbar. Seems like not every foam, maybe even most foams can take it. Hardness is not a criteria, the foam I used is a wobbly as eps foam can....
