Custom/Hybrid wet laying visual carbon?

[Brian_216]

I am finally ready to get building on my visual carbon Gen2 hull. I am wondering how you guys go about doing this and not disturbing the twill? I have a few ideas, 1 brush resin in the mold, lay carbon in dry over it and wet out in the mold. 2 pre wet carbon on the table, squeeze out excess and lay it in wet. Option 2 makes me worry, I know what happens when we wet out fabric and pull it off the table. Im looking for the best way to not disturb the weave. The whole thing will be sanded and cleared after its cured, and any seams or mishaps in the weave will either get an accent color stripe, or decal over them. We also use thickened epoxy with cabosil in the corners of the mold to eliminate fail areas, what can I do when doing a visual layup? Other than resin infusion, Im looking for advice.

Here is an example of the proposed bottom deck layup schedule:

1 layer 5oz carbon
1 layer 5.5 oz kevlar (tear resistant layer bottom deck only
1 layer 17 oz biax glass (1708)
1 layer 19 oz carbon
1 layer 17 oz biax glass (1708)
1 layer 19 oz carbon

This is a guess at this point until we lay up a test panel.
additional 19 oz will go in over mounts, inserts and bond rail

Feel free to discuss.

Good luck with that...

Wet layup of Visual Carbon is actually TONS more work than it's worth, especially on a ski with all the tight compound areas. The minute you start, (after HOURS of prep) You start to say to yourself....WTF am I doing here!!$$!!

After you pull it from the mold, there is actually more time wasted trying to "fix" the imperfections to make it look good.

Not to get into details, but the "Fuctional Carbon" is the more realistic approach for a regular wet lay up....but you know that already.

I found that when laying up large pieces it was easiest to apply a generous amount of resin into the mold and lay dry carbon into it. I actually pre weighed all my resin the the amounts that each layer should take to wet out and applied most of it to the mold / previous layer before laying down the next layer. It was easier working with smaller batches of resin and helped me keep a better resin/cloth ratio.

Are you going to bag it or just hand lay?

IMO your layup schedule looks a little light.
My bottom deck is
20oz 12k carbon
20oz 12k carbon
1708 double bias cloth
1708 double bias cloth
20ox 12k carbon
20oz 12k carbon

Stock superjet bottom deck with bulk head and engine mount inserts (almost 2lbs each) wieghed in at I belive 36lbs

you gotta to spend the time and learn or find somebody to infuse it if you want it visually perfect
good luck as I have been there many times

The way I see it, if it isn't 100% perfect ill paint it, or lay out graphics.. Who knows it may only have a little visual like a carbon rickter and a paint job just showing some carbon. I just want to try it. As far as the layup looking, light we have tested our hulls with 5 layers of 1708 and it was vac bagged epoxy. They feel very strong once cured. I just edited the layup for the bottom adding an additional layer of 1708

Hallo Brian, try to layup the sides off botton visualcarbon. You have flat areas only. You can learn wile do this and next hull you can try an area on topdeck.......

5 layers of 1708? Jesus that thing must be a tank

It's funny you say that, others would argue that's too light. The first ones were 7 layers on the bottom deck. 5 layers has some flex before the decks are bonded.

Have any luck yet on laying the visual carbon Brian?

Didn't get there yet. Placing my order Monday

wow, my master plug pulled from my mold is
3 layers side
4 bottom outer
5 flat middle bottom
ALL 1208

And its heavy!!! more than strong enough

Honestly don't go off what other people say, take there advice and store it but don't let it bother you 5 layers of 1708 is really strong man. What brand glass are you using? And what was the weight of that hull with 5 layers?

A 5 layer hull is close to 80-85 lbs with hood. The 7 layer one we made is like 110.

1708 w/chop or no chop?

More to come we have been swamped between orders and our 40 hr jobs, ya I hate regular work and would much rather be laying up ski's. I will say that there is a nice pile of carbon waiting.

Here is some wet lay Carbon Kevlar on one of the Brawler hulls

Does carbon lay about the same as fiberglass of the same oz? I thought you had to vacuum bag carbon.
