For this assignment I used my previous mold, made for the moulding and casting assignment, I didn't make a new mold because  I wanted to explore the possibilities of reproducing the same geometry using different techniques the mold was modeled in Rhino there I made an "organic" surface which I later mechanized using a CNC router, I used the software Aspire to program and get the G code.  Despite resins casting and fiberglass processes are different the wood mold was very useful in both cases.

For the composite process I followed the next steps:

-First I coated my wood mold with a  release agent in this case I used a special wax.

- I poured the gealcoat (already catalyzed) all over the surface making sure not to have empty spaces; is very helpful to use a brush to help the gelcoat to distribute homogeneously.

-Once the gelcoat was solid I started placing the fiberglass and the resin.

-After the resin was perfectly catalyzed and hardened, I carefully removed the fiberglass piece from the mold, thanks to the correct application of the release agent  was very easy to take it off.

- The result is a copy of my organic geometry, which is very light, with a remarkably resistance and an exact copy of the desired surface even the little imperfections were copied.
