Hi there,

I've made a mould to produce Carbon fibre loops, the dimensions of the grooves are 5x5mm, which is the intended cross section dimensions of loops.
Initially I had an idea of taking carbon fibre loops out of mould and vacuum bagging them then i realised the might change the square cross section of loops which i want to keep.

So I wonder if vacuum bagging to whole mould with fibres in grooves will be efficient in this case or grooves too small?

And do you recommend any special arrangement of vacuum bagging materials?

Hi Fred,

What I'm making is carbon fibre loops. I make them by winding 12K carbon tows around mould many times.
So far I got  low fibre volume, (about 45% fibre, 55% resin) as I didn't use vacuum bagging.

Now I'm thinking of use vacuum bagging but as you can see in the photo the grooves are quite narrow (5mm width, 5mm depth) so I wander if vacuum bagging will make difference! as not sure if  peel-ply+breather+vacuum bag layers can stretch to apply pressure on each groove.

Thanks
Mohamed
