Hi all. I’d like to show you my lasts work about composites.

I’m  very found in Hydrofoil kiteboarding, so in the past 10 years I do some models

This is the last one. The idea was to build something different  from the models on the market, an hydrofoil easy, stable, and possibly fast.

 Some pictures:

In this video you can see the first trials.

In this one the building process for the board.

Can you tell something more about molds you are making? From which material do you make those green molds?
When you are molding elements (wings) from solid carbon, how are you calculating amount of carbon to be put inside (if you put too much it will loose shape? if to few, it will loose strength?)? Did you think about making wing from two separates parts (infusion) and then glueing them together?
Does your mast have wooden core, or it is also solid carbon?

Hi, the molds were made with       https://www.easycomposites.co.uk/epoxy-tooling-gel-coat
I think it's easy and smart material for the mould surface. The thickness and the strenght of the mold is given by several layer of glass fiber (chopped and some woven scrap) and epoxy resin. Fot the TBar's moluld I add also some wood.

When you are molding elements (wings) from solid carbon, how are you calculating amount of carbon to be put inside

It's a little bit empirical, in other experiences, I noted how many layers (and their weight/m2) I used and the thickness reached for planar objects.

Did you think about making wing from two separates parts 

It's what I do

and then glueing them together?

In my opinion isn't enough, You have to join also with a fabrics.

Does your mast have wooden core, or it is also solid carbon?

It's full carbon, various pattern and some Hight moulus.

I am a little bit confused - here you are opening mould with wing and right before you were presenting stack of prepared layers of different size. This suggest that it was made in single process. i guess that it requires specific amount of material to be put inside.
Making it from two separate parts (infusion?) would require such precise dosing of material. (wing form two halves might be hollow inside?)


You mean full like this

or more like this

but fully hollow?
