Good morning all you composite people!

I've been trying to use masking tape on my lovely expensive fabric (210g carbon/kevlar twill) both to mark it out for cutting (ie drawing on the tape, not the fabric) and to prevent the edges thus formed from fraying.

I've tried el-cheapo masking tape from a certain major UK DIY retailer; it sticks too well and I makes a mess as I peel it off.

I've tried both orange and green "frog" tape (I had both colours lying about) and that certainly doesn't stick too much. In fact it hardy sticks at all and lifts off whilst I'm trying to cut along my lines.

What else do people use/do to mark fabrics and protect the edges please?

Thanks,
Robert.

The only thing you could use the way you are doing it is something like Airtech Airhold, which is a double sided tape used for positioning materials for infusion. It is designed to stay within the stack and so doesn't affect interlaminar bond strength.
