Your design looks pretty amazing! That said, having riden CF decks for the better part of the decade, I can tell you that pure carbon fiber boards are a poor choice for skateboards. One of my composite decks is 100% carbon fiber and foamcore; while it is incredibly strong and responsive, it transmits all of the road vibrations, and your feet are literally numb after riding. And this is with shock risers and plush wheels. This was a ~$350 deck… and now it basically just sits in the corner.
Compare this to a board I ride every day… Rayne Demonseed Deelite. It has carbon fiber stringers with fiberglass plies laid over a wood/bamboo frame with foamcore. It is light and strong, but still has great vibration dampening characteristics. My point here is that it is not as simple as “carbon fiber all the things!!!”
Carbon fiber is a high strength, high modulus (stiffness) material. Using a flexible resin doesn’t change these inherent properties. You’d be better off incorporating other fabrics, such as fiberglass and kevlar, which have high strengths but lower modulus.
