Hello, i’m new to composites and i am making a kiteboard. I bought some pvc foam from easycomposites and have glued two sheets together a 20mm sheet and a 3mm sheet to give my required thickness. I used gorilla glue and applied it all over in a zig zag pattern. The bond is good apart from the edges where there are some bits that are lifting as they didnt have glue. I plan to vacuum laminate with carbon cloth and then apply a epoxy coat to finish. 

I am hoping that because i’ve got good bonding overall and because its the same material sandwiched together and i’m laminating around the edges it wont delaminate later. What do you guys think? should i do something to remedy or just crack on?
thanks!
