Carbon Fiber Chainplates

Zednotzee · 30-10-2009, 18:38

I read a recent review of the Hanse 630e which, as it turns out, uses carbon fiber chainplates. This seems like a great idea- no more corrosion issues. Is anyone considering something like this for a refit? Are there any disadvantages to a carbon fiber chainplate?

I have seen those on another design, glassed into the deck, and it looked like something I want to have and the only disadvantage I can see is the money they cost or the time to build them yourself... but our chainplates are attached on the outside of the hull and easy enough to care for in steel.

cheers,
Nick.

we spec'd 'em for a recent cat build, and love 'em. for new build, the process was NOT that complex. for a refit, i'm not sure. attached is a "pic" that shows how we did it.

That pic is the side of a quarter, makes it hard to tell

Basically, they were made from fiber bundles wrapped around a thimble. Great for spreading stress on cored hulls. I used them on a honey comb hull for that reason.

It did not take any longer than potting holes and bonding backing plates, really, and was very compact. They can easily be built WAY stronger than they need to be, eliminating many engineering concerns. I would prefer to use them in combination with a lashing, vs a SS fitting.

Mine are composite, but unidirectional fibreglass, not carbon. TBH I think carbon might save a couple of kilo's, compared to glass ones, but not more than that.

sorry... trying to make pic actually viewable.

Seen on Schionning, probably the way to go in a new build plastic but not as a retro.

Thanks everyone. I had just assumed these would be a bolt-on replacement, like an aftermarket carbon fibre car hood.
It would seem these are quite state-of-the-art. My only positive internet search results are two threads on this forum!
The other thread linked to this, if anyone's interested:

Worth noting in that link that they have a 316 s/s tube sleeve in the chainplate as I do on my anchor bridle attachement points, but I was told to wrap the S/S tube with fiberglass first as there can be some corrosion or disimilar material issues

I wonder what happens in a lightening strike?

If ya gonna have fiber chainplates, you are going to HAVE to have fiber rigging also....no more worries about lightening......well at least less worries

Cat man do: you did it right, they did it wrong. I have had galvanic corrosion between carbon fiber and metal... it ain't pretty!

cheers,
Nick.
