Hi all, I would like to know how estimate resin consumption over infused foam panels, Do they consider their density?
I’m watching that infused panels are quite heavier than standard bagging panels.
What methods can be used for decrease resin uptake?
Regards and thanks
You cannot avoid resin uptake. It is actually the course surface of the foam that is getting filled. This is done more efficiently with infusion than with wet bagging. For sure the adhesion of the laminate is better when doing infusion.
Basicly the only option to reduce resin uptake is using another foam. Higher density usually means smaller cells, and less uptake. Also there are heat rolled foams (Airex T92 SealX)
T92 SealX appear a great product, I think that only absorb 200g/m2 or less per side vs 500g/m2 (correct approximation?) for standard foams. However It appear difficult to found for my, probably I never have acces to this foam, (I’m amateur level).
Then.
Could higher density to make lighter parts by a lower resin absortion in the foam?
Maybe, Could I use an adhesive film with a preimpregned cloth layer (50g/m2) with resin epoxy (estructural adhesive)?
I should make infusion before this layer will be cured fully, for assure a good adhesion between this layer and infused layers.
