Fiberglassed phenolic tubing is extremely strong and able to handle nearly any flight profile you can imagine. It comes to you pre-glassed, initially sanded, and almost ready to paint.

When to use Fiberglass Wrapped Phenolic Tube:

For any rocket expected to exceed 0.85 mach.
For any rocket that may encounter rough handling or hard landings.
When a little extra weight is not an issue and a lot of extra strength is required.
