1. Preliminary Detailed Design Review
P17701 ABVI Upcycling: Cotton Insulation
Lucas Jackling, Mitchell Goepel, Samantha Kon, Denning Crenshaw

2. Agenda Objectives for this design phase
Detailed run-through of material requirements (BOM)
Discussion of product test plans
Plans for next phase
Questions/Concerns

3. Objectives for Detailed Design Phase
Develop project Bill of Materials (BOM): “What do we need?”
Acquire prototyping materials to get started
Order larger quantities of shredded cotton: primary material resource
Research product testing, develop simplified tests for comparing prototypes

4. Update on Shredded Cotton Procurement
Team determined that middle material seen at left is very similar to Bonded Logic shred material
Therefore, acceptable to order more and use to make prototypes
Have 50 lb of middle and right shred on the way from Fiber Conversion

5. Tentative Bill of Material (BOM)

6. Prototype Form Designed in Solidworks
Will create a 7” x 7” x 3½” thick prototype
Made out of 2x4s and plywood board

7. See additional handouts for detailed test reports
Product Test Plans
See additional handouts for detailed test reports

8. R-Value Test
An insulation prototype will be sandwiched between two pieces of insulation with thermocouples in between
The temperatures are recorded after a given amount of time
Using heat transfer principles the R value will be solved for and compared to current insulation products

9. Smoke Development and Flame Spread
An insulation specimen will be placed in a fire-proofed location
A flame source will be applied for pre- determined amounts of time
Recordings will be made to identify smoke developed and flame spread

10. Sound Transmission Test
5 sides of a box will be made of acoustic insulation
This will ensure that most of the sound exiting the cube will be through our prototype
The last side will be our prototype insulation
A speaker playing a constant tone at given frequencies for a set amount of time
The microphones will register a difference between inside the box (with the speaker) and outside the box (transmitted sound)

11. Fungal & Bacterial Growth
An insulation prototype will be subjected to water
The prototype will then be placed in a container and covered in a constant temperature environment
After a period of days the fungi and bacteria will be measured

12. Corrosion Test An insulation prototype will be subjected to water
It will then be placed on a copper plate
It will be maintained at a constant temperature for a given amount of time
The copper will be visually inspected for blemishes

13. Moisture Absorption Test
The mass of the prototype will be measured
Then, the prototype will be submerged in water
It will then be taken out of the water until it stops dripping
The change in mass will be recorded

14. Full-sized Sag Test
Prototyped insulation will placed into a structure that resembles the shape and size of wall studs.
Humidifier will pump moist air into sealed test apparatus.
The distance the insulation sags will be recorded and then analyzed.

15. Plans for Next Phase - Detailed Design
Acquiring raw material to begin prototyping
Running additional feasibility tests (product and business)
Developing bill of materials
Developing test plans
Researching additional topics as needed
