vac infusion Q:

General Composites Discussions Composites Talk
#1

hey guys, what is the size of mold that you would have to use more than 1 inlet and 1 vac out let port?

Size of mold is 4.5 by 2 ft
Vac using pulls 20 microns at 6cfm

Or would you just use the activator that has the longest cure time?

also has anyone used the spirel tubing wraped with peel ply around the outside of the mold to aid in flow?
any tips on use?

thanx for any help…[/quote]

You’ll probably need more than one inlet but never more than one vacuum port.

That wouldn’t be a bad idea. It’s very common in large layups.

I’ve used spiral tubing lightly sprayed with 3M 77 adhesive and rolled peel ply over it. Worked like a charm.
