Hi everyone,

I am from Lafayette Motorsports and I am trying to implement carbon fiber A-arms. We manufactured aluminum plugs that inserted into the carbon fiber tubes with a bond gap of 0.011 in. The epoxy that I used is Loctite 9340 Hysol with glass beads with a diameter of 0.007 in. Each of the surfaces was roughened and cleaned prior to application of the epoxy. I let the epoxy cure for 4 days and then tested it in the Tensile tester, and the epoxy began to pull apart at 500 lbs. Is there a better process or epoxy that I should use in order for the epoxy not to slip at such a low force? Any other suggestions would be greatly appreciated.

Thanks for your help.
Brendan
