Waterproofing Prototyping

Material: Protective Rubberized Cotton Flannel
Total Test Time: 8 minutes
Checking Interval: Every 2 minutes
Depth: 2 feet 8 inches
Waterproofing Test of the Protective Rubberized Cotton Flannel

Waterproofing Test of the Protective Rubberized Cotton Flannel

Results: After 8 minutes of testing, there was no water in the jar. Tested material again after taking one side of cotton off (placing rubber on outside of jar). This also passed this test as no water went into the jar after 8 minutes of testing.

Fabric Area: 21 cm x 21 cm

Original Fabric with Two Sides of Cotton:

Fabric After Removing One Side of Cotton:

Decision: We will use the fabric with only one side of cotton as it is more lightweight and still waterproof.
Next Step: Stitching Waterproofing

Test Plan Summary

The complete test plans can be found here. The testing priorities are summarized in the design review material section, as an attached PDF. Our main goal for this phase is to verify that the material we purchased will suffice, and that our design will perform as expected.


  1. Ensure test plans are in place
  2. Ensure that all applicable test standards have been cited (e.g., ASTM)
  3. Ensure all ordered materials have been received
  4. Ensure team has space and equipment necessary to begin building and testing
