Has anyone had any success ordering tri-axial fiberglass from anyone. I ordered a couple yards from snowboardmaterials.com but it's still not here and it has been a month. I ordered some other materials from them also and they also took forever to get here... I have all my other materials I'm just waiting on the glass. I'm excited to get my projects started, so I can try a couple of skis out this winter. Any ideas would be awesome.

i recently checked the snowboardmaterials.com site and they put up a note saying that all orders will be delayed until after Christmas or New Years. can't remember the exact details but that's probably what's causing the delay.
maybe someone has some extra that they're willing to sell?
Try some of the boat building guys in Maine. They should be able to give you some scrap, or at least a supplier. Or call vectorply for some samples. Fiberglass supply also has what you are looking for.
Try hamilton Marine in Portland, they will have everything you need. If you make it down here I will fill you in on the progress of my project.

Brian were you able to get triaxial glass through Hamilton... I called the Portland store and they told me that they don't carry triaxial.
Does everyone else get their triaxial glass through snowboardmaterials.com I've seen vectorply on the site before but, I thought you'd have to order in bulk.
thanks for the ideas...

I have been getting some fabrics here. They have always been good to work with. It is a boat building site.
They list lots of biaxial fabrics and only one 22 oz triaxial fabric. I have used a 17 oz. biaxial fabric w/no mat that is two layers of loosely knitted together unidirectional materials.
Is that how the fabrics from snowboard materials are made?
I haven't touched them yet and can't tell from pictures on the site if they are the same.

Anyone have m5 magnetized cap inserts?
I am designing my first set of skis and was wondering what the advantages of using carbon fiber and kevlar would be over fiberglass? Both materials seem to be included in higher end skis, but do they improve the skis enough (i.e. the kevlar helping to damp vibrations and the carbon fiber creating more stiffness) to be worth the extra investment? Any insights would be greatly appreciated.
Thanks,
Renee
There has been a good discusion here about the virtues of carbon.

And some more info from these sites about both.

You need to be careful where you place both materials in the composite. Kevlar does poorly in compression, and in a ski needs to be put under the core. It was stated in the above thread that the carbon is poor in compression, but I have found info in my "boatbiulders manual" that carbon rates very high in compression and poorly in tension, so would work best above the core.
IMO, neither is worth the price for a recreational user. Kevlar is 3x the price of glass and carbon is 2x the price of kevlar (in comperable weight). You could make several sets of glass only skies for what you would spend on either of these two materials.
