Hollowboard kitesurfing

Hi all,
the aim of this work is to obtain a light, confortable and cool kiteboard
Instead of use an usual PU or wood core I tryed to generate something similar to honeycomb.
At first it needs a lot of meters of carbon’s tube… so you have a roll a lot…
For the top and botton sheet I chose the carbonkevlar for its elongations properties.

I show you some picture and a quick video with the building process.

Some photo

looks awesome!

Cool it is, but how’s the wheigt?

I just started taking a mold out of a surf kiteboard. Want to do it hollow aswell except where the pads are. Your core looks interesting

very nice, i like the golf ball effect

how many layers each side ? and what weight of cloths used ?

also, did you just have a bow and no rocker on the board ? did you just sand the tubes to the desired thickness ?

ciao

Great job and I enjoyed the video as well.

how many layers each side ? and what weight of cloths used ?

2two layers carbon kevlar 200 gr/m2 on the bottom 1layers Carbon kevlar 200 gr/m2 + 1 layer 200 glass 200 gr/m2 on the top.

also, did you just have a bow and no rocker on the board ?

The board has about 20 mm of rocker

did you just sand the tubes to the desired thickness ?

Yes, but it’s not so easy .

but how’s the wheigt?

The naked board is about 1,8 Kg

This week end i’ll start the work for a new one!
