wood/carbon core matrix
Posted: Sun Jan 04, 2015 5:53 am
Just got back from the French Alps and some good skiing with the kids - did some nice off piste at the beginning of the week but it crapped out thereafter.
Just thinking about a new build also - in particular core construction. In the past and as per I use a vertical laminates. I am currently considering an ash/spruce combo for my next skis. The lay up would be thus
base
15.5oz biax
3.5oz UD CF (full width)
Core (11mm)
3.5oz UD CF (full width)
15.5oz biax
fabric
Topsheet
So far so normal, although a critique of the lay up would be appreciated. I am hoping that the light biax glass would be offset by the carbon in terms of flex, torsional strength and pop etc.
This leads me to my question - have any of you ever tried interleaving the original core lay up with UD carbon between the strips of wood? so the core lay up would go (using epoxy to bond):
Ash
UD
Ash
UD
Spuce
UD
Ash
UD
Ash
That would then be sliced as normal to produce two planks for the cores. On a couple of my surfboards, the central stringer has a line of carbon down each and it is just an extension of this idea.
Any input greatly received - I have done a pretty thorough search but haven't been able to find anyone posting about this.
