Infusion speed

Hi all,

Just a quick one.
I infused some small items recently, approx 300mm x 150mm with:
650g 2 twil (mould surface)
3 layers of 200 unidirectional
Then top layer of 450 2
I then added peel ply and infusion mesh.

The top surface just about wetted out, but the mould surface didn’t wet at all.

Is there a particular problem I’m having or is there perhaps a way to slow the resin flow to allow it to saturate all layers?

Many thanks,

Bill

I think it is your uni materials too.

You can add a layer of a woven cloth in between the uni layers to help the resin pass through better. 

Does anyone have a suggestion for the material/weight of the material to use in between layers?

Anything woven or stiched  as long as it creates a new feed path through in-between the uni layers.
