Process for Insert Tensile Test

1. Cut CF tube into ~3-5 inch sectionsCreate Aluminum inserts

   1. 0.004-0.012 in gap

   2. Leave shoulder length for Instron machine to grab

   3. Have a length of about [some] inches that will adhere to the inside of tube

2. Cut the Carbon Fiber tubes into about 3-5 inch sections

   1. The tubes are 5 feet long, so we can get at least 12 tests from one tube

3. Prep the surfaces

   1. The aluminum inserts will be sanded, degreased, submerged in etch solution for 3 minutes, then submerged in non-diluted Alodine solution

   2. The CF inner part will just be sanded and degreased

4. Add Epoxy

   1. We may test mixing the epoxy with small glass beads to properly center the insert, or use of Flashbreaker tape

   2. Slather chosen epoxy on the insert and inner part of CF tube

5. Insertion

   1. Slowly push insert into tube and let cure for 24 hours.

6. Testing

   1. After putting the insert into both sides of the tube, attach to Instron machine

   2. Pull until failure
