Carbon Fiber?

Got a bunch of this from a buddy for free, claiming it to be carbon fiber. I literally can not snap this small 1/8" scale in half or even bend it for that matter. So makes me think it may be CF. But its only black on one layer on the top and bottom. And white inside. Could this still be CF?

Probably CF with some sort of core material. This is how they do cf in industry keep weight down.
The core material is often a weak foam or honeycomb material and needs to be sealed up/covered to protect it.
 
Ok. Well its not foam. It looks the same as the black just its white. Not sure if they will make decent knife scales. Lol. Unless I can dye it.
 
Carbon fiber can come in different colors. This may have been used for a particular application that requried the two colors. I say use it as is.
 
Hm. ok. I just hope I can make it look decent as I have enough to do at least 50 full complete handle sets!

does the white stay white when you make it wet?
Isn't it just the coars scratches that make it look white?

If the core is white see it it as e special feature that others don't have
 
The core could be nomex. Sometimes nomex is layered with CF to add flame resistance. Think race car construction.
 
Looks like itchy stuff that needs to be worked under water, or with a very serious respirator.

I'm leaning towards this too; try getting the rough scratches out and throwing some water on there; if it shows up the same color/appearance, then you just need to get it past the early shaping stage and it should be ok.
 
I have some materials left over from a bullet proof wall for a court room in my town it was white and looks like cf.
so I took some of the scrap home. Long story short looked it up on the mfg. Website and I believe it said it was a blend of kevlar and fiber glass its very dense and heavy . Unknown if it could be used as a handle material.

I was under the impression that Kevlar can't be dyed (or bleached) white. Perhaps it's another aramid fiber?

Also, Kevlar becomes damaged by uv ( I think) light, which will discolor it from its natural yellow.

A blend should be yellow and white, although I was also under the impression that ballistic use is in its cloth form. The type (49?) of Kevlar used in conjunction with cf would be structural.

I'm totally willing to concede if anyone knows any of the above to be incorrect. Just random memories from doing research on thread (leather work) and cut/abrasion resistant motorcycle apparel.

Anything with an epoxy base can be damaged by UV unless it is coated. Kevlar is supposedly very hygroscopic so it REALLY needs to be sealed.

I have Kevlar rope but it has a covering of another fiber for the UV problem. But Kevlar does stop a 44 mag quite well !!
 
Be very careful with unknown materials. It's often not worth the risk. ask me how I know....

I got what I thought was a scrap piece of brass from work.

After fighting to grind it and being shocked at the wear resistance of it I did a little research.
Turns out it was berilluium copper

Bad bad bad
