Do you like my Carbon Fiber?

[Slant]

HI, Just found some unidirectional 8.9oz carbon fiber. Does any one have an opinion of how well it would work for this fiber used as one layer and maybe using some triaxial glass on the other layer?

I am using vertical grain bamboo cores and I am trying to keep the boards light as possible for the strength.

Thanks for the input

I see it comes in a 24" width. The problem with unidirectional is that it is very difficult to cut it into smaller widths and keep it together. I tried it before and as soon as I cut it, the fibers started falling away.

I haven't tried it yet, but I was thinking if I taped the area that I was cutting, it would hold the fibers together. Or, you can just look for material in smaller widths.

Thanks for the heads up. Maybe if I cut it to the length I want and keep the width the same throughout (ski width) and try to cut along the lengthwise strands. I think I'm gonna give it a shot anyways...

It should hold together when split lengthwise into six inch strips because it has the hot melt binder in the fill direction.

I use similar uni-carbon in my ski lay up, two layers of 4.5 oz, one above and one below the core (vertically laminated bamboo). I also use 20 oz biaxial glass (+/- 22 degrees) as my bottom most layer and 20 oz triaxial (0, +/- 45 degrees) as my upper most reinforcements. I think the carbon adds "pop" to the skis.

If it has that to hold the fibers in place then you should be okay. Mine didn't have that, and it caused problems.

whats the thicknesss of the core? This sounds like a retarded stiff ski.
Am I wrong here or does that sound like a grip of glass and carbon?

well maybe not, 8 oz carbon, one bi, and one tri, interesting. high end dood.

Spray a mist coat of spray adhesive (3m77) which ill hold the fibers together, stop fraying and not not screw up the epoxy. I do this when using uni for model airplane wings.

If you are using a uni-axial layer you will want to have either a +/- theta biax on that same side or another triax layer for torsional stiffness.

I would be careful if you are spraying an adhesive on the fibers in ski applications - you could jeopardize the fiber to matrix bond strength.

just ordered some carbon from carbon sales . com great communication and good prices.
