Characterizing Fabric Breathabilities for various SoCal Climates

What?

● A setup dividing tank into two sealed chambers for timing humidity transfer through fabric

● AME431b Mechops Course 6-week Junior Year Project

How?

● PTC OnShape for part design and iteration

● 3D Printing with TPU for cartridge function, Laser Cutting for top and shutters

● Iterated 4 times to verify best possible seal despite quick 2 week turnaround

Results:

● Success: Minimal additional sealing utilized, operational shutters to begin data run 

● Allowed for 10+ hours DAQ without seal degradation

● Data concluded polyester as the most breathable for better breathability in SoCal climates
