I have a very stupid problem and feel too ashamed to ask it. Since I started working with carbon i had this problem, remember i taught myself. As everyone knows as soon as you cut a carbon sheet its starts to disintegrate. So i learned you have to tape down an area before you cut it. ok this works very nice, but say for example you want to make a seam or a joint somewhere in your part or tool, then the tape is in the way, the weave doesn’t conform like it should, and impregnating doesn’t happen like it should. How do you manage to make a practically invisible seam, without a weave that unravels? Remember I’m referring to wet lamination or infusion here, not prepreg.
One of the things that bother me the most, you get some carbon hoods with a distinctive “V” seam right in the middle of the hood. How do you manage to make that?
Thanks for the help guys.
Spray adhesive and light glass fabric. Most times a light layer of spray adhesive is enough.
You could try a stabilized(dissolvable binder) twill weave, don’t know if you can get that in south africa.
I use a lot of backing film like paper/foils. Wet out on the backingfilm, then cut, apply on your mould, and get the backingfilm off.
we get a product called ‘epoxy coated carbon fibre’. but i was told it only prevents weave distortion. Is there someone out there that can illustrate this procedure with pictures?
Another way is to wet out an oversized piece on some plastic sheeting or bag material. Then put another sheet of plastic on top and squeegee out any air bubbles. Then trim to size. This helps give crisp edges on wet layups.

Someone did a tutorial on V-weave products. Had a load of pictures ho to do it. Who can find the thread?
Didn’t evan just fold the fabric to do this?
