I need advice how to laminate flat sheet with fiberglass.
There are 3 sheets 25 mm honeycomb already joined so total size is 2.4m x 3.6m.
I am just in the process of covering whole surface with double glass canvas and epoxy but I am afraid that bubbles still
appear beside intensive rolling over with flat aluminum roller.
Should I cover whole surface with plastic sheet and vacuum it or apply something on top ?
I am afraid that bubbles could create the weak points later and cause spot de- lamination.
If too late save that one at least next time I will be better informed.
Looks to me as if you haven't got enough resin on that.
I'd pour the resin directly onto the cloth and use a squeegee instead of a roller, to spread the resin around.
You could be right, but I wanted to avoid filling honeycomb with resin.
I am afraid that resin will leak into cells and fill it.
Quality honeycomb should allow to penetrate , but that cheaper version from Nuplex may leak.
This way I need apply 3 layers of epoxy but only one fiber matte ( every few hours).
This will be my new deck for my electric catamaran
roll out glass on a table covered in plastic sheet (taught - no wrinkles)
Pour on resin and squeegee (that should = minimum resin and no air bubbles)
Lay honeycomb on top of wet-out glass and weigh down with a sheet of 5 ply or MDF so it is contacting the glass well everywhere.
There ya go, no resin dribbling into cells.
Then repeat with other side.
Thanks , I need to do one more for roofing , so I could try this method.
I need to make very big table I think two yellow tongue flooring panes should be enough.
