• Mechanical Tests

  • Tensile Test- needed for plug

    • How to test it

    • Probably not needed since the push rod will be under constant compression

  • Flexural Test

    • three-point and four-point bend testing according to ISO 14,125, ISO 178, ASTM D 790, and ASTM D 6272

    • parameters for this test are the support span, the speed of the loading, and the maximum deflection for the test

  • Impact Test

  • Compression Test

    • End loading

    • Sheer loading

    • ASTM D 695, ASTM D 3410, and ISO 14,126.

    • information on elastic limit, proportional limit, yield point, yield strength, and compressive strength

• Strength at high temperatures (Summer)

• Fatigue Failure?

Plug Testing

• Adhesive

• Adhesive thickness (Depends on Diameter of Insert)

• Adhesive depth (Depends on Length of Insert)

• Steel or Aluminum?

• Buy or Manufacture?

• CF prep styles

• Metal prep styles

• CF prep depth

• Length?

• • Loctite

    • EA E-40HT

    • DP420

    • DP460

• Tube and metal prep

• Aluminum stock for insert

  current inserts are

  • Check for appropriate lengths

  • Gap 0.35004 - 0.5 inches deep

    thinking process:

  • carve a tube with some clearance of OD from ID of tube

  tap the carved out part to make a threaded insert

  012 in

  • Carved aluminum, tapped for fitting a bearing insert

  • create shoulder only for grabbing in tensile test

ASTM D 695 (compression test)
