Week 8 Progress Report
Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Reinforcement hoop components completed
Waistband belt seal completed
Reinforcement ring segment tested using 3 point bending test
Waistband belt seal tested
Began wire outlet research
Accomplishments from Previous Week
Fabricated curing frame
Fabricated 5 ring segments using the carbon fiber sleeves (using curing frame)
Conducted a 3 point bending test on an old carbon fiber ring segment
Finalized design of ring segment connections
3D printed 5 segment connections
Sewed cloth pouch onto waistband belt
Tested pressure leak with waistband belt and foam insert
Researched wire outlet addition to top plate
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Order a small amount of neoprene to replace the cloth pouch (Jen)
Replace cloth pouch on waistband with neoprene pouch (if neoprene arrives in time) (Jen)
Order memory foam samples to test with waistband belt (Jen)
Assemble and test a full reinforcement ring (Jen and Jackie).
3D print rope fixture connectors (Brian and Jackie).
Order wire outlet hardware (Geoffrey)
Install wire outlet onto top plate (if hardware arrives in time) (Geoffrey)
Conduct multiple FEA analysis on carbon fiber rings with different numbers of layers and directions (Brian).
Buy more insulation foam for ring segment layups (Jackie).
Reinforce 3D printed connection segments with carbon fiber sheets (Jackie and Brian)
Fabricate and test 2-segment ring design (if time allows) (Jen and Jackie)
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Analyzed critical ring deformation load using elastic stability analysis suggested by Prof. T.
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Can test the strength of our ring segments with a UTM possibly, or with a one point load - we conducted a 3 point bending test on a ring segment
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
N/A
Risks and Areas of Concern
Stability and potential failure of connection joints.
If the reduction in pressure leakage will remain the same (or comparable) if we increase the maximum pressure difference
Resources or Information Required but not Available
N/A
Schedule
On schedule with waistband seal and reinforcement ring design and manufacture. Pressing on wire outlet design on the top plate.
Budget (list amount spent and amount remaining)
