I managed to break my HF board due to XPS delamination and planning to make a new one with EPS core as it bonds better with epoxy.
I want the rails to be bulletproof as I tend to hit it with my harness hook before waterstarts. Should I use UD carbon fibre or kevlar tape?
The layup would be 2x160g glass (or 200g) top and bottom and a few layers of UD carbon tape under the foil for additional support (4 bolt foil mount).
Is it Ok to mix glass and carbon under the foil for more stiffness or should I stick with glass reinforcements only? The carbon is way less flexible then the glass so at extreme load the carbon could break before the glass?
