Hi
I've started basic layups and struggled a little cutting carbon cloth.
At the moment I'm using 200g 2x2 Twill 3k Black Stuff Carbon Fibre (1000mm).
Low Cost Carbon Fibre for General Use
Easy Composites' Black Stuff™ products are a range of no-frills carbon fibre reinforcements woven to a more basic specification and which do not carry our usual full certification. Black Stuff™ carbon fibre is intended for use in non-visual applications, backing layers, mould making and general commercial use. It is not suitable for critical cosmetic applications, aerospace use or other uses where a CoC or fibre certificates are required.
In mechanical properties and general handling Black Stuff is still a great performing all-rounder and is actually comparable to the general purpose carbon fibre sold by many suppliers.
This 200g, 2/2 twill Black Stuff™ fabric is woven from genuine 3k carbon fibre (Formosa TC35 3K) with a specification and mechanical performance similar (but not as good as) our standard range of carbon fibre fabrics however it does not undergo visual inspection and is woven at a higher speed and therefore some imperfections can be expected. Black Stuff™ also uses a slightly lower modulus fibre than our standard 3k carbon.  
These are my first efforts so using cheap carbon to practice with.
I have proper shears from easy composite. First attempt was messy, second attempt today I taped area with I was cutting with masking tape. This was a big improvement but found it easy to deform raw fabric.
Is best to use one long piece or maybe 4 25cm pieces? I then found the masking tape was too good so cut once on the glass plate.
Is cutting with scalpel a better practice? What effect does leaving masking tape have on the infusion?
Thanks for taking time to read my post
