Hi, so I have this mould that will be used just one time and theb scrapped.
It is made with epoxy gelcoat and a few layers of 200gsm cloth laminated with epoxy.
I want to infuse the part and I think the mould is too flexible for the job.
What do you suggest as the cheapest way to stiffen it?
I was thinking about breather cloth impregnated with cheap polyester resin but maybe you have better and cheaper ideas?
Thanks for any advice!

Yeh the forces involved in print through are very strong. It is typically more an issue for elevated temp tooling, you tend to get away with it more for ambient stuff, but it can still catch you out. I've had 1 or 2 bonnet moulds that were 10mm thick rapid tooling reinforcement and they still suffered print from the support structure. Will see if I can find the photos.
