I’m sure some of you have seen the Carbon Dry Japan products before. But here is a video close up of one of their wheel overlays.

If you scroll down to the bottom of the page you can see they list prices. I converted 80,000JPY to USD and it came to $982, that’s just for one car wheel. http://www.carbondryjapan.com/protec_en.html

So anyone going to try this?! :stuck_out_tongue: I’m sure someone has to have a spare sports car wheel laying around.

so lets talk about how this is done?

ive tried overlaying some intricate shapes before and i cannot get them to conform to the shapes as well as this.

982 sounds about right, maybe a little low priced.

Think about having to overlay the backside of a wheel like that.

we quote wheels between 2K and 4K a set depends on complecity, and time. An all carbon fiber mfg’d set will run around 12K a set. we haven’t done a set yet, maybe some day.

Carbon dry i think uses prepreg… i may be wrong but it wouldn’t hurt to cure an aluminum part at 200F without changing the heat treating of it. the only thing i can think of is possibly the wheel would ecpand ( no damn ecs key) during heating and the carbon … well it wouldn’t.

they used a single piece of twill for the entire top of the spokes. and guarantee they cut it or cut relief cuts in that piece before appling the cf. The wheel was done in at least 12 pieces or more.

ah thanks mate, exactly (aprt from the technical words) my thinkings

#5

I counted 16 pieces. At least thats how I’d do it.

1x top layer
7x for the inside spokes
1x or 2x for the well
7x for the back side of the spokes

It has to be pre preg. It would never come out that smooth if it was wet laid up and then coated / sanded several times.

I’m thinking if its pre preg, then peel plied perfectly with no pleats, then vacuum bagged with a billion pleats, and then a few coats of clear with wet sanding in betwee

That looks amazing! But I’m not sure I understand about the amount of pieces used, I know carbon isn’t very giving on curves but with so many pieces of carbon wouldn’t it cause more issues or be messy trying to deal with so many bits? I tried to look for join lines but couldn’t see any…

#7

Very nice job but I would be worried carbon to come apart from the wheel while spinning 7.0000 rpms

^^Wheels typically turn under 1,000 rpm even when on the highway.

^^^ HAHA!

To the question about not seeing any lines. If you match the weave its very difficult to see parting lines. Especially on
a computer screen.
