Eu quero fabricar uma nadadeira de fibra de carbono, tamanho 90cm por 23cm, já tenho o molde mas não sei qual a bomba de vácuo certa para usar comprei uma mas não funcionou!
Tem alguém que pode me dar essa informação? e-mail eversonsc@hotmail.com Fone: 48 33421099
hell shkssj88, I don't know how to produce a pin-hole free surface using the method shown in this video.
The normal way to produce a nice finish is to is a negative(female) mould for the part. You start by painting a gel-coat or epoxy/polurethane-paint into the mould, let it cure, and then laminate glassfiber+epoxy on top. The gelcoat/paint produces a nice surface. If you google for "pikanto mould" you will find my blog and my latest model-yacht project which uses this technique (not infusion)
It may have been better to use a couple layers of infusion flow netting down the center attached to your epoxy line rather than the sprial wrap, only because you probably had quite a bit more waste resin this way, but at least you were guarateed epoxy would get to the far end quickly!

next time don't put your spiral wrap that close to the vacuum side and use some media flow for resin distribution

google for "sp guide to composites" and read that!

explanation of what's happening would be more useful than music.
