Help with identifying this glassing process

Hi all!

I've been building my boards for some time now and always looking for new and interesting ideas.

Found the German manufacturer - Carved, with an interesting pattern on the wood and hoping you can identify what that might be?

They are laying some kind of webbing here:

The core is also perforated and by the look the tiny, hardly visible webbing is there (on the right hand side, black ticker one might be a printed topsheet):

Two questions:

1) What is a webbing?
2) The perforated core, is it for better bonding the top sheet and epoxy excess flow?

What do you recon?

Thanks

Fiberglass veil??
I have seen this perforated balsa or poplar in the wakeboard contruction. Process fllow of epoxy like you said as its vacume.

I don't know if that is the glass you can see, but maybe it is.
The photos on this page suggest that they create a grid of shallow lines on the core as well.

the "handmade" tab

I am not sure what effect that net of fibre would produce as they sound like they are using 800-900gsm fibreglass as well

Interesting. I am not sure either. The perforated core might be ok, but placing this veil looks like too much work of no real benefits.

Thanks for the link.

I think the black is carbon fibre laid at 45/-45. I think I read it on the site somewhere that this board uses carbon fibre for torsional stiffness.

True,

if you go on "Custom boards" than "PXT 4 Custom" there are two models like "X-Carbon Custom" and "Wood Custom"

Again, not sure where on Earth one would find a carbon veil like that. But as they say:
" Perfection of the torsion rigidity
by uniquely laying
diagonal Carbon fiber strings"

Maybe it's a hand made layup...?

I think Wagner uses that carbon layup too. I think I saw some a Burton when I was there too.

Most important point to remember is that they have very good marketing. One example is their 60 degree biax fabric... ;)

The cores are perforated and the grid are small channels for better resin flow, they probably use infusion but im not 100% sure about that. Therefore the webbing is maybe only for the vacuum process and removed afterwards. It is not visible in the finished board. They don't use plasic topsheets. No idea about the black webbing, didnt see that one in real life.I guess carbon rovings...

Cheers Christoph

Edit: It's on their website: "diagonal Carbon fiber strings"

Nice finding Christoph, danke.

Tried to find this product on vectorply.com, no joy (or I'm blind:).

MM, would you know? Ta[/url]

I think this is the manufacturer of the carbon webbing: http://graphitemaster.com/

Still unsure about the light webbing in the first picture. Probably something secret from the aliens they bought from a mongolian shepherd :D

Cheers, Christoph
