Soric infused mould for pre preg use?

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.

Ok I'll probably do this.

Vinyel ester gel, csm vinyl ester skin layer, infused vinyl ester 5 x 400g carbon each side of 1-2 layers of 4mm soric.

100C cures for the pre preg parts.

This is a proper rigid layup. Is this for one of your boat hull moulds? Interested to know what you're doing that needs such a mould!

This mould is for a yacht boom, it's 2.5m long and 400mm wide including flanges but only a 25mm high profile so it's kind of long and flat like. I wanted a core for stiffness and carbon for a stable oven mould. The 12k 400g is cheap anyway so 4 or 5 layers each side wont break the bank.

This part was from temp moulds and now we will make better moulds.
