TCook Posted September 8 Share Posted September 8 Hi I’ve tried an infusion using release film instead of peel ply to help stop any bridging that could be causing print through. Which you can still see in the photos. However the main issue is the vast amount of voids. You can see big sections under where the foam core is but also on the faces where there isn’t foam. I used a perforated release film and wasn’t filled with confidence during the infusion. The flow over the top of the film was perfect however it seems there isn’t enough resin getting through into the layup. any ideas on how to fix this issue? Admittedly I might’ve infused too fast for the film but I have had issues with it in the past even when infusing slow so I’m wondering if there is a way to improve? Any advice on the resin pooling print thought would be appreciated also. I’ve chamfered the foam at 45°, used a roller and spray tack to make sure the carbon isn’t bridging however it still has print through. It is still a lot better than the print through I had with the peel ply. The print through also printed onto the mould surface? Quote Link to comment Share on other sites More sharing options...

Missed this one! @John Kimball or someone else might have some input 😀 Quote Link to comment Share on other sites More sharing options...
