Updated Project Risks

● FieldTex and NexoTherm collaborations● Possibility of packaging, sewing and manufacturing the garments

ourselves ● Research on additional vendors

Materials Consideration● Inside layer: moisture management

○ Goal: move perspiration away from the body○ Material that will wick moisture away from skin○ Solution: synthetic fabrics

● Outside layer: insulative and lightweight○ Goal: trap air to maintain insulation of cooling packs○ Solution: Natural fibers or classic fleece○ Synthetics including Thinsulate

● Continuing research on materials for both applications and working with FieldTex on initial materials so that they can be tested

PCM Consideration● PureTemp 23

○ Paraffin based○ Best properties based on PureTemp data○ 326 KJ/Kg of cooling○ Purchased unencapsulated sample○ $20/lb

● NexoTherm PCM○ Unknown properties○ Petroleum based○ In possession of encapsulated samples○ $200/L

Updated PrototypesThermaCollar ThermaBelt

FieldTex Collaboration● Local manufacturer of soft-sided cases (bags, vests, straps, etc.) for

military and medical applications● Capacity to manufacture short runs or large quantities

○ Designers and over 85 sewing machines in house

● All three prototypes can be easily made - will initially focus on belt● FieldTex will provide proposal and prototyping quote● Materials available in house for prototyping

○ Velcro compatible material for outside○ Multiple material ideas for inside (lycra, mesh, heating pad slip cover material)

FieldTex Prototype Proposal● Lead time to produce and ship a sample: 3 weeks● Lead time for a production order: 4 - 6 weeks● Sample cost: $50

○ Firm pricing for production order will be given once sample is made

Test Plans

Test Plans

Project Plan for Detailed Design Phase● Complete outstanding design items - finalize designs by the end of MSDI● Continue preliminary testing - gather as much data and information as

possible by the end of MSDI● Vendor consideration for garment prototypes

○ FieldTex meeting○ ABVI meeting

● Plan for MSDII○ Preliminary timeline and schedule of activities

● Detailed Design: 11/23 - 12/10○ Complete Design Process - 12/9

■ Test plans■ Laptop decision and purchase■ Garment design consulting with ID team

○ Preliminary Testing - 12/8■ Test all purchased materials to ensure they meet requirements■ NexoTherm vs. PureTemp vs. ice

○ MSD II Planning - 12/8■ Preliminary project timeline■ Budget discussions with extended team

○ Ongoing updates - 12/9

Activities to be completed by the end of MSDI

Timeline: Phase VDetailed Design

Deliverables for end of MSD I - Status updates● Completed test apparatus design

○ Critical path: ■ Approval to work in BME labs ✔

● Preliminary testing completed and data collected○ Critical path:

■ Approval to work in BME labs ✔■ Water-based prototype received from ID Team ✔■ PCM Company delivers materials and/or prototype ✔■ Testing protocol written ✔
