Problems using closed cell foam core

Hi all

I've been lurking on here for a while and have recently started making some parts for a project car.  I've started using resin infusion hoping to get a more uniform finish and like everybody (I guess) I occasionally get voids where I havent gotten my cloth in to the corners but I'm also getting surface voids along the edge of where I have used closed cell foam as a stiffener.





The above is 2 layers of 200g carbon, the stiffener then another 200g layer on the back, any advise on what I'm doing wrong would be appreciated.

Thanks

Thanks for the input guys.

I did consider chamfering the edges of the foam but completely forgot again until after i'd finished my leak test!  best make a check list before i attempt another.
