Wrapping Peel Ply Around Spiral Tubing For Infusion

If your resin is flowing in though the spiral wrap and you have only peel ply between the inlet spiral and your laminate then the resin flow will be 100% impeded from going anywhere fast other than through your spiral wrap.

The inlet piping or medium must have a decent contact and flow path to get into your laminate and any core or other flow mediums.

Some (including myself) will use peel ply only in contact with your outlet side vacuum channel/spiral tube/or other so that the resin front will near stop at your vacuum perimeter without filling your vacuum channel/piping/plumbing/spiral wrap.

It’s called a peel ply breaker, no need for wasting money on products like MTI hose.

Hanaldo is incorrect as the peel ply only will maintain a vacuum continuity, it’s no good for resin flow if your talking about having peel ply only on your inlet side.

Apologies, my post was misleading. I meant that it does not impede the flow of air in the vacuum channel. Then with regards to the inlet, I wrap mine to protect the bag, though I haven’t had any issues with my bag being punctured when I don’t do it.

Wasn’t intending it to sound like it should be used on the inlet instead of or without flow media.
