got some, ill test it soon. seems heavy. seems like it would work best between base and fiberglass. any ideas montucky?

I bet the fleece is to help keep the epoxy under control. Maybe its giving them flatter bases? I doubt it provides much structural effect or dampening benefit.

Have you used any innegra yet? I built a pair a couple years ago with a layer in it. I built an identical pair minus the innegra to compare it with, and then I sold that pair like an idiot. I really liked the skis, and put 40-60 days on them, but I'm not sure how much the innegra effected the skis other than making them heavier.

This is my comment BTW and I meant to mention I have some innegra if you want some. I think its a standard weave about 4-6oz in weight.

Sounds/Looks like it is being used to protect the structural integrity of the FG layer.

PH, if you'd be willing to put a small sample in a small envelope, I'd be interested in seeing it.

"Structural integrity" is a buzzword Rich :) I don't quite follow what you mean?

Haha - not meant to be. Apologies if that's how it came off.

I thought there were two interesting points in the data/research. The first was the relatively high strain to failure percentage. The second was the impact test results/examples. In the absence of a 'catch all failures' titanal layer, within the Kastle example, I was assuming this was their solution? Could be quite wrong ... who knows what they mean by fleece???

Preserving the integrity of the FG layer (base) is not something we've really discussed. It not the biggest concern when home building, but different solutions are captured in various videos/online resources and I'm interested in finding a solution. Perhaps I was just trying to give a new thread a heading?

Very keen to know your thoughts about the material Twizz!

At first glance I just hear a tiny voice in my head saying "heavy!".

So by structural integrity, you're thinking impact resistance. That makes sense, but I would think there are better solutions for that (biax kevlar), and I personally don't think base impact is a common failure point for skis/boards.

But like you said, who knows what they mean by "fleece". I'm envisioning a cut-off piece of my sweater sleeve stuck inside my ski, and I know it's not that thick!

I've heard engineers in aerospace say things like "this will improve structural integrity", and sometimes you have to poke that a bit more - what does that even mean? :)

When I read 'fleece' this is what I thought of: http://www.freemansupply.com/AirtechUltraweaveB.htm

We use this stuff all the time at work but as a process material. It never ends up in the finished product. It's used to control the resin bleed out and resin flow during cure. Maybe this fleece is used to ensure full resin coverage over the edge teeth? I've heard a rumor of a local builder using some cloth "filter", that is sort of fleece-like, for this very reason. I think they were using thin strips over the edges. Anyway they got flatter bases and the edge teeth didn't show through the base anymore.

Could this matetial be used instead of the edge rebbet?
added weight for dampening and ease production?

I think it could be. Those skis are very heavy!

The kaestles are very light I'm not sure what numbers you see but 2000g per ski at those lengths/widths is not very heavy.

Just held them in my hand and they felt heavy. Maby the numbers show different..

I stopped doing an edge rabbit since I have a 3" wide strip of CF under my core in all of my skis. Not quite as thick as the edge teeth, but it's close.
