I am thinking to try a vinyl ester  infused soric and carbon mould for use with pre preg processing.

Laminate might be 6 layers 400g carbon each side of a 4mm soric (maybe 2 of 4mm soric in areas) to make a thicker stiffer mould.

Anybody tried using a soric mould like this? I know there maybe be air left within the soric cells but it all very well supported? Heat/expansion??

Or should I use a few layers of flow mesh or shade cloth and leave in the centre of the laminate? This would mean no air in the laminate leaving a core of resin/plastic mesh.
