Hi guys, there is some trick to cut the carbon fiber fabric, and do not fray, I've seen a spray for this that you have to let dry. I'm interested in curved cuts, thanks.

Try a mist of spray tack before cutting. EC sell Fusion Fix and I regular use Aerofix 3 available vis East Coast Fibreglass
I also use an Olfa roller cutter which is great for getting nice clean cuts. You'll also find that using a 240/245g twill fabric will also have a tighter weave pattern so is further resistant to falling apart when cut.

+X[citar]Pruebe con una red de rociadura antes de cortar. Venta de EC Fusion Fix y uso regular Aerofix 3 disponible con fibra de vidrio de la Costa Este También tiene un cortador de rodillos que es ideal para obtener cortes limpios y agradables. También tiene el uso de una tela de sarga de 240/245. También tiene un patrón de tejido más ajustado, por lo que es más resistente que cuando se corta.

the safest way would be to use stabilised fabric. number two, and my favourite, is to use grid tape, wich you can find in any hardware store in the rendering section. works brilliant, is as cheap as it can get.

I have found that, whilst a fabric like EC's 'Pro-finish' can be good for getting neat cuts without fear of the fabric coming apart, the cut edges can still exhibit some fraying if not handled with the greatest of care when positioning.
You also lose a lot of the drape characteristics that might be desirable in moulds with a bit of shape to them, so treating a 'normal' fabric in some way to reduce the chance of fraying can often be a more favourable way forward. It's usually a little more pricey, but the common range of 240/245g twills are so much nicer to work with and trim than most 200g alternatives and also tend to look better when laminated, due to the tighter weave pattern

100% agree Mark.
I don't like commercial set-weave fabrics personally, they lose the benefits of a twill weave fabric. I prefer to use a regular loose fabric, and use spray adhesive when I need to make precise cuts. Often this means you can keep the fabric loose when draping it into the mould, and when it is virtually in place then you give it a quick dust with spray adhesive before making your relief cuts.
I like to stick to 240g fabrics as well. Nicer to handle, and in my opinion a classier appearance than standard 200g wovens.

I think if I used normal 240g fabric with adhesive, one question is the adhesive before cutting the fiber or after cutting it? the short with rotary cuter.

You give it a light spray before you make the cut, and give it 5 minutes or so to slightly lose its tackiness a bit (so it doesn't grip your scissors as much). Make sure you spray the back side of the fabric, not the side that is going to be visible.
For extra stability, you can tack together two layers of fabric. This will let you handle and cut the fabric almost like a pre-preg, but you will lose the drape and flexibility of the dry fabric.
