Phenolic Airframe Tubing
PT-1.1PT-1.1
Regular price $17.07Phenolic tubing is a resin impregnated, spiral wrapped, and heat cured tube. It is much stronger than cardboard tubing, with almost 5x the compression strength. It is also a very good base for rockets that will require the strengthening of fiberglass, Kevlar, carbon fiber, or similar materials. For this reason, we recommend phenolic as the appropriate tubing for rockets that are 6.0, 7.5, or 11.4" in diameter, or rockets that will require strengthening for the rigours of transonic or supersonic flight. We also recommend phenolic for transonic or supersonic flights in kits of 1.1" through 2.5" diameter, as phenolic can withstand those flights without strengthening in most instances. PML Phenolic tubing is very heat resistant and is highly recommended for motor mount tubes and minimum diameter applications.

These are nice strong tubes for higher power rockets. They tend to crack and break on rocks, so I use the quick and dirty pantyhose method of strengthening. Use gloss polyurethane and a couple of laminations of pantyhose legs the tube becomes really tough, isn’t much heavier, and I don’t have spirals to fill. Also, pantyhose come in a variety of colors and patterns and look great not painted.
