I am working on product that is comprised of aluminum sleeves affixed to carbon fiber tubes with structural adhesives. We have tensile tests that show we have more than enough strength for normal use. However, I am looking at the
200 degree service limit for the adhesive and wondering just how hot this part might get say, sitting in the sun out in Phoenix in the middle of summer..... It's winter here in Calif. so hard to collect data. I might ship some parts off to a friend in OZ to collect data as it's summer there. But thought I'd ask if anyone here might have done any testing of this nature and know.I have approx 3/4"dia by 2" long aluminum, bonded to 1/2" carbon fiber. This resides near an engine, so worst case would likely be a hard run through the desert, then being parked with this part in direct sunlight while taking in heat from the engine.
Once I have an good idea what temps we might see, I can specify in the next tensile test that the parts be heated to this temp before being pulled.
Thanks,
Jon
