Ideally looking for multidirectional layer circular tubes (multidirectional best for drivetrain members since likely undergoing different stresses & also easier for calculations; circular tubes since stronger than square and not much mounting necessary for drivetrain members). This means likely twill weave roll wrapped or maybe braided depending on expected forces/stresses. Also depending on forces/stresses, tube OD guesstimating between 1.25 to 2" (32 to 50mm).
...
Possible options based on online available selection of finished tubes:
- Plain Weave
- Only one size available: 20mm x 18mm x 1.2m ($25.58)
- Twill Weave
- Range from 13mm to 32mm OD, from 0.75mm to 1.5mm thickness
- Largest and longest available: 32mm x 29mm x 1.5m ($77.11)

Rock West Composites
Much larger online selection, but prices are much more expensive even considering the 15% student team discount.
