Thought I would share how I make V weaves. This same method can be use to cut text and logo’s out. To keep the weave straight you just spray adhere another layer of Carbon behind your visual layer. This way when you cut with the Olfa cutter your material doesn’t start to fall apart.
First pic shows the razors under the tows that I want to pull out to give a straight line for the Olfa cutter to follow. Second pic shows them pulled out. Then in the third I layed the backing layers on the sides they will be adhered just for a visual reference on here. Before you adhere them you want to make sure the side you are adhering them too is straight and that’s what the fourth pic shows. Then in the fifth the backing layer has been adhered. The sixth and seventh pic show the same thing just for the opposite side. Once the backing layers are on you can cut away. I didn’t take a pic because my battery’s were dieing but I use the rule as a guide along with the missing tow line so I can just run the Olfa along the edge of the rule. After you have your two pieces cut you want to spray more adhesive on a large layer the size of both pieces, this will be the layer you use to butt the two together on and hold them in place. It shouldn’t be too hard to butt them together because the backing layers keep them pretty straight. The eighth shows the final V weave.
Here is another pic of blue and red hybrid butted together, ignore the dust on it because this isn’t being used for anything just was a piece I made to show a friend how to do it awhile ago and it’s just been sitting in the shop since.
What are you cutting with?
Olfa rotary cutter, the best thing besides a Gerber table to cut material with.

Looks nice Rotorage. Don’t try the rotary on Kevlar or CF/Kevlar hybrids as it won’t even dent the fabric, let alone slice through. 
Maybe they should make a serrated rotary blade ?? Hmmmm.
Thanks. Actually I have used the rotary on Kevlar and hybrids. I have two dozen blades so I just change them constantly to keep a clean cut. I should mention that I get them sharpened alot from a local fabric business. It really helps to use a good amount of pressure and run the edge of the blade against a hard template or rule like I used in the pics above. Sometimes one swipe of the blade isn’t enough and I will run the path twice but you still end up with a clean cut.
You mention the serrated blade. I tried serrated with Kevlar before and had the worst results ever. Maybe I didn’t have the correct size serration? :blink:
Besides the Rotary blades I have a couple sets of Ginger scissors, obviously one for Kevlar and one for Carbon. They work AWESOME for me and were only $35 each I think at Michaels. I like them alot better then the multi hundred dollar scissors that composite shops sell.
Another idea I’ve had for cutting material is to make a reverse air hokey table. Lay material on table, cover with painters plastic, turn on vacuum, trace patterns onto plastic, then go to town with the rotary cutter. I think it would be the poor mans Gerber… 
Or for those of you with a router table you could add the vacuum table if you don’t have one already and find a drag knife or tangential knife to make your own Gerber.
No kidding -(to Kevlar cutting) ? Wow…maybe I was cutting an odd material highly cut resistant ? I used a fresh blade too…wouldn’t touch a strand effectively.
I bought a case of blades on ebay for shelf stock. They worked great for all my CF and E-glass…just no go on the Hybrid Kev.
If you want the V already woven into the material it looks like Soller Composites has some V 4x4 Twill back in stock.

Sorry for the crappy cell phone pic because it doesn’t show the text or surface finish good. The finish is class A and you can see the same method used for making the V can be used to create text. I tried to make each letters thickness 3 rows of 3k for a 9k total width and it’s carbon/Kevlar.
