Which is stronger for bending: tube or rod?

Hi,

I crashed my RC airplane (again!) and broke the 6x4mm carbon fiber tube in the wings.
I'm looking at replacing it with something stronger this time. The stresses are bending only - no tension or compression length-wise.

Which of the following would be the best?

  • 6mm carbon rod,
  • 6mm (4mm inner diameter) carbon tube,
  • 6x4mm carbon tube with a 4mm rod inside?


Thanks,

Mattias

I suggest you use customized tube with optimized layup angles. These available standard sized tubes may not meet your requirement.
