The video's of these new yachts being constructed dont really explain it very well.


Do they place carbon in the female mould, add resin in the vacuum, then let it cure. Then add the sandwich layer with another layer of carbon on top and repeat the vacuum / resin / cure process?

Layers of prepreg carbon, which already has the correct amount of resin in it, is layed into a female mold, vacuum bagged and cooked so the resin cures. After the first cook, glue film is layed over the cured outside skin and the core (typically nomex honeycomb) is placed on top of the glue film, vacuum bagged and cooked again. Lastly the inside skin of prepreg carbon is layed over the core, vacuum backed, and cooked for a final time.

Nomex honeycomb has served Farr well in the past. Why change?
