I came across a nice knife the other day which had a handle made out of “30k” carbon fiber. I can’t understand the weave, and how this structurally would be strong?
Can someone explain why the carbon fiber looks like this? This is a very high end knife.
There are spots it looks like it was twill weave and other’s that remind me of a harness weave. I would say twill if I had to pick one.
It looks like that because it was probably just a lot of plys layed up to make a thick plate or “stock” that was then cnc machined to the shape you see. That’s why it has the neat look.
The “30K”… No clue maybe just a marketing name.
It looks like a 3k fibre but it has been sanded/machined to cut through the layers giving the interesting patten. Should be ok strength wise.
^ What he said.
Thats real cool!!! However, if I saw that when I was overlaying one of my parts for a client, I’d freak out and start over.
Good way to use offcuts.
I would say that looks like 2x2 twill 3k that was layed up as a thick plate and was then machined to its current shape. a very messy job to do! Looks very nice tho.
I only have experience creating very thin laminates.
Would infusion, wet layup or compression molding be the easiest way to make a ‘thick plate’ like this?
I want to add some customization to my existing knife, since i have some spare twill lying around. But am unsure on which method I should go for.
If it’s going to be machined, wet layup and bag would be the easiest.
That said you don’t want to hit a void or resin rich spot and have it crack.
I’d infuse it veeeery slowly.
+1000 This is sanded, that’s why take this surface. If you are sand one twill way part you will have the same results. I done this many times.
Grafil makes a 30k tow. However, that is a LARGE assed tow.
