Matt,

I was wondering the same thing, but I think it is tape to protect the topsheet.

Those are some nice looking skis!

Buuk- Pretty cool. I remember when I had access to Matlab for free in school ... Did you create your own code for the FEM in MATLAB, or are you using another application like Nastran, Ansys, Cosmos ...? If you are using a canned application, how are you integrating the results into Matlab? Also, for...

thanks for posting my link. The 10 post rule is fine - see I'm one post closer to ten.

OK, I finally kicked out a pair. My inaugural pair is called the Ghetto Fly. They are 184cm and ~ 138 - 108 - 128. They have a Pine and Poplar laminated core that is about 9mm thick underfoot. The sidewalls are wood and the tip spacers are glass. For the graphics I used green cotton fabric with logo...

I was finally able to get a couple of my test coupons to bond pretty well by using a belt sander with very coarse stripping paper. Since I've got a ton of it I went ahead and used it as my topsheet for my first skis. I may not have sanded enough on my topsheet and I'm afraid that top-sheet delaminat...

OK, The first round of test coupons didn't bond so well. I did three coupons of Acetate on wood. One cleaned but no abrasion and the other two sanded with a fine or coarse grit paper. I was able to peel off all three, but the abraded sheets did bond better - oh well. I'll probably try a few more thi...

I stopped by the Boeing Surplus Store today and got a ton of clear cellulose acetate sheet for cheap. It is pretty thin (~ 0.5-1mm), very clear, and kinda feels like a slightly softer polycarbonate. My initial search on the web makes me hopeful that epoxy will bond to the stuff. We'll see, if I have...

Interesting discussion here. One thing to point out is it is probably more usefull to compare material modulus/stiffness rather than strength for ski performance. It is my understanding that Carbon Fiber is stiffer than Aramid Fiber which is stiffer than glass fiber (long - tension). And like was st...

That helps a lot - thanks Geoff.

Hi All- I've been lurking around the site for a while now and would like to thank everyone for making this site such a great resource. :D I am getting close to pressing my first pair of skis; I've got my press, mold, core profiler, and most of my materials amassed - except triaxial fiberglass. I wou...
