Has anybody heard any thing about further developments with this:

This technology would probably lend itself to windsurfing and make a fairly tough everyday board. A highly polished alloy board would look dead sexy too!

Reckon we should email him and ask him where he is in development and can it be adapted to Windsurfing boards(his email is on bottom of article)

Would be great to have a realy strong windsurfing board. We recently damaged two of our boards within a week of eachother.

Imagine how quickly it would corrode from the inside if it let in any water.

good point shane !

then they might have to look at cathode and anodes running through the board to give it neautral charge in the metal when in contact with salt water!!!!
just like the technology they use when constructing bridges over salt water !

geez did i get too technical then !

Sorry to say after building composite ships for the Australian Navy and doing impact and destructive tests on steel v’s aluminium v’s composites. I personally would not go near aluminium for a sailboard. Composites are much much more resistant to flex, impact etc.
I recon the Aluminium on a sailboard would crack like a dry riverbed in the middle of the desert.

sounds like the board is sinking before it is even on water !!!!!!!

It is composite, isn't it? as there is a mechanical bond with foam core

quote:

The 0.6mm thick aluminium skin increases toughness but keeps an ability to flex, creating a smooth and comfortable ride.

They have a higher resistance to impact and do not suffer fibreglass rot, delamination and ultraviolet degradation.


One of the keys to the invention has been the perfection of a secret technique to apply molten aluminium to the foam core without melting the foam.

And importantly the skin forms a mechanical bond, rather then a weaker chemical bond as is the case with fibreglass.



interesting development. see how he goes

Oh look, I got a star!

Do I wear it on my lapel, epalette or forehead?

The patent specification can be found at:
http://pericles.ipaustralia.gov.au/aub/pdf/nps/2003/0227/2002300981A1/2002300981.pdf
He has let both his Australian patent applications lapse. I suspect he has run out of money for the project because patent protection would be quite important if this had any real commercial legs.

I wouldn't be holding my breath on this one, guys. It might be a good idea, but it has to compete with some pretty well established and proven technology. And I can't imagine that applying molten aluminium to a foam core wouldn't be one hell of an expensive process. How much energy would it take to melt aluminium?

It would be an interesting process, I imagine the aluminiuim must be sprayed on if it's .6mm thick.

Trouble is most current windsurfing boards have a double carbon sandwich (not just a foam blank with a single outer layer like this).

Aluminium is a great material but I agree with Moose, I don't think .6 of a mm would even be close to a double carbon sandwich in terms of flexural strength and crack resistance.

I imagine it would dent very easily at .6mm. I can't quite work out how you would get a good seal around the deck fittings and finbox etc. It would corrode, and it might be a bit tricky to repair.

Apart from that it's a great idea for anyone who wants to look like a giant fishing lure...




PS where's my cat gone?
