You either need to seal the flanges with something before bolting them together, or you will need to envelope bag the entire thing. Envelope bagging I find quite unreliable for infusion due to the propensity for leaks, especially on larger complex moulds like this, so I try to avoid it. for sealing the flanges, the easiest and most reliable way I've found is to use an RTV silicone gasket maker (do NOT use an adhesive caulking silicone, these will bond your flanges together regardless of release agent). The downside is this is a bit difficult to clean up after the infusion, so it becomes a bit of a pain to reuse the moulds. Another way I do it is to run a 'bead' of gelcoat all around the flanges, and then bolt the flanges together before the gelcoat cures. This is significantly easier to clean up, but doesn't seal as reliably as the silicone gasket. Using either method, don't forget to seal up your bolt holes as well.

The only doubt I have is how to arrange the taky tape all around the perimeter, without any leakage, especially where the vertical and horizontal flanges join or in other parts where there are fairly tight curves. Maybe it's my inexperience that makes me see the problem!Another way I had thought of to proceed with the infusion was to slightly cut out the upper flanges to create a bead of a couple of cm along the entire perimeter to apply the taky tape. This way I would only have to finish the top flanges and would only need to seal the bolt holes. What do you think about it?I hope I explained myself.
