The final decision was to dye the epoxy used for the top fiber, and to leave the bottom carbon fiber clear. The dye was selected because it was easy and minimized the amount of extra layers needed. Additional graphics could be incorporated into future boards.
===Layup TechniqueProcess Selection===Under ResearchUsing Granta CES, three possible processes were selected. Autoclave, vacuum bagging, and hand layup. Hand layup was chosen as it has the lowest associated cost. Significant research was done into the layup techniques in order to try and perfect our process, but hands on practice could help in the future. Below are some videos that were used, along with many not listed. The general layout was first using UV epoxy between the foam and fiber. We did not have enough sunlight, so this step would be eliminated in the future. Next, normal 2-part epoxy was layered over the carbon on the bottom of the board. While 3/4 of the way hardened, the fibers were cut even with razors. The board was then flipped and the two layers of fiber with epoxy between and on top were added. Next, the entire board was sanded smooth and wiped clean. A final hot coat of epoxy was added to ensure a smooth finish, and then a surface coat (not epoxy) was added. [https://www.youtube.com/watch?v=_73JZE1B730 Glass Layup]
