Completed final mold.

Argosy International. The layup was
done by a team member crawling in
through the cockpit opening and
manually applying each layer.
Cleanliness was maintained by the use
of hairnets and lint-free suits. Each ply
shape was designed so the plies easily
fit over complex geometry, improving
efficiency with minimal overlap and
ensuring the overlaps occur in different
locations for every layer. The plies were
cut using a computer numeric-control
fabric cutter. A copy of the layup guide
and a ply checkoff sheet are always
accompanied by the manufacturer to
prevent mistakes.
To achieve a sandwich structure,
three cures were required-the first for
the outer face-sheet, the second for
the bonding of the honeycomb, and
Layup process.
third for the inner face-sheet. When
the cure for the final part was done, the
drill bushings that are laminated in the mold were used to jig
and guide the drill for the attachment holes in the final part.
Afterwards, the mold was finally unclamped, releasing the
final part.
The T31 monocoque would not have been possible without
the blood, sweat, and tears of everyone that was involved in
the project. Countless hours of sanding and late-night layup
shifts are some of the best memories that I will take away,
along with the priceless engineering experience. n
