Imperfect surface finish on resin infused part

Guys,

I have just de moulded my 2nd resin infusion from the mould. The results are good, but not great.

My laminate consisted of three layers of carbon using the easycomposites infusion resin, peel ply and infusion mesh. The mould was treated with easylease and the part demoulded quite easily. The surface finish of the part appeared a little resin starved with consistent but very slight surface voids throughout the part surface.

I have actually achieved better results from vac bagging. Any suggestions why I'm not getting the perfect finish I was expecting? I had a full vacuum on the part throughout the infusion.

Advice would be appreciated.

Thanks Warren,

I'll try that tip on the next infusion. It's a steep and expensive learning curve!

It certainly can be Crying

I do infusions on almost a daily basis so I don't think there aren't many mistakes I haven't made over the years. Smile

Another little tip is to place a circle of breather cloth and peel ply directly underneath the vac outlet connector. This will act as a choke slowing down the resin when it reaches it. This will give any areas that are lagging behind the chance to catch up without wasting resin into the catch pot.
