Hi all,

Just a quick one.
I infused some small items recently, approx 300mm x 150mm with:
650g 2 twil (mould surface)
3 layers of 200 unidirectional
Then top layer of 450 2
I then added peel ply and infusion mesh.

The top surface just about wetted out, but the mould surface didn’t wet at all.

Is there a particular problem I’m having or is there perhaps a way to slow the resin flow to allow it to saturate all layers?

Many thanks,

Bill

That's great. Thank you both.

Do you have a photograph or maybe a link to illustrate this 'resin break'?

Thank you very much,

Bill

The peel ply goes under my resin line, across the layup and resin brake area, as well as under my vacuum line. It’s a must for uniform vacuum.

I use spiral wrap for my vacuum line and mirror it to the resin line.

I use peel ply over the resin line, and the vacuum line to protect the bag from sucking in between the spirals. The peel ply also prevents the lines from collapsing at full vacuum (which if you notice in the pic, I didnt take the time to make sure the lines didnt collapse, will work either way).

Alternatives to running peel ply across the resin brake is to take individual tows of glass or carbon and run them across the brake to the vacuum line. Spaced out like 1 inch apart. It’s even slower than using a peel ply brake, but does not effect the speed across the flow media, just the speed of the resin across the brake area. This was my old way, but now I’m lazy and just do full peel ply.
