Default Peel plying and compound curvature

Hey all,
Is there any way to peel ply a lay up with a lot of compound
curvature, or a more "stretchy" peel ply variant?

You can also cut regular dacron fabric of the bias and make it work.

There isn't a stretchy peel ply.

Best thing to do is find teflon coated fiberglass "release ply" for
vacuum bagging. Like this

Cut it on the bias, in relatively small pieces. The size depends on
how tight the compound curve is. Overlap them.

What does bias cut mean? (me dummy)
and if it is the peel ply I've been using, how do you cut it period?
It's almost as bad as Kevlar!

Thanks Cam

The reason I go to teflon glass is it's easier to remove. When you're
doing small pieces (playing card size) on a tight curve, dacron drives
you nuts - hard to get started peeling, then you only pull for a
moment and you have to start again.

When teflong glass is overlapped, the top layer barely bonded at all -
like, the bond strength of a post it note. So it's easier to get
started, that's all. Bias cut dacron will certainly work otherwise.

Fabric is normally cut along the thread line, But bias cut is at 45° to
either thread line.
