The purpose of Group 15’s project is to pick a manufacturing
process for a composite part. Thus,
the selection is not a specific design but rather a plan on how to choose
the optimum process. The group is
researching different methods and materials continuously to be more
informed. A summary of basic
research can be found in the “Manufacturing Research” section
(included). This section is a living
document that will be updated as research continues and decisions are made.
Group 15 has
narrowed down the world of composites and decided to focus on four main
areas; reinforcing material, resin, bonding process, and curing. The possibilities for each area as
follows:
·
Reinforcing
material
o Glass Fiber
o Carbon Fiber
o Glass Fiber
·
Resin
o Polyester
o Epoxy
o Vinyl ester
·
Bonding
Process
o Resin Transfer
o Contact Molding
o Vacuum Bag
·
Curing
o Autoclave
o Room Temperature
With research, the group will combine
the best of these areas to create four fuselages. These will be tested with a drop test at
different angles and velocities to simulate different landing and crashing
situations. These models and their
performance will be compared to expected properties in order to narrow the
field. Any unusable design will be
removed at this time. The group will
then rebuild and test practical design to ensure consistency. A selection will be made from information
gathered from these constructions and test.
After a selection is made the group will get quotes from
manufacturers on small-scale to large-scale production of this fuselage.
