4. Preparation of Vacuum Bagging Materials
Required Materials:
- Peel ply (light-blue)
- Release film (should be light red, make sure it's perforated)
- Bleeder fabric
- Vacuum bag material (Stretchalon 800, resistant to up to 400F)
- Ruler
- Scissors
Prepared vacuum bagging materials
Vacuum bag was too big (32" x 38")--> make smaller next time
Waited to cut excess off peel ply, release film and bleeder fabric until started vacc bag
5. Tip-to-tip Layup
Mark centerlines on tube and CF cutouts
...
For the tip-to-tip layup, we used a total of 6 boats of epoxy. Each boat weighed (INSERT MASS)118g, not including the mass of the epoxy boat itself, so the total mass of epoxy used was (INSERT MASS)for the tip-to-tip layup was 708g.
6. Vacuum Bagging
Vacuum bag was 32 x 38" (this is TOO BIG, make smaller next time. For the test fin can though the bagging was too SMALL, so find a good middle ground)
...
Positioned fin can horizontally as shown, because there wasn't enough vertical space in the oven we used. This may have caused the fins to splay (weight of the tube + epoxy loosening --> fins move), so in the future we should position it vertically. (try taking out the rack, for example)
8. Post-processing
Vacuum bagging materials were difficult to remove, but not impossible
