Preparation of Vacuum Bagging Materials

Prepared vacuum bagging materials

Tip-to-tip Layup

Mark centerlines on tube and CF cutouts

CF didn't meet up in certain places (ends of tubes, some were barely large enough to cover the fins)

...

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)

Oven Cure (ATTACH SOP)

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.
