PML carbon fiber tubes are not filament wound. They are convolute wrapped ("roll wrapped", similar to the way G-10 tubes are made) using actual aerospace quality carbon fiber cloth. The cloth we use is a very tight satin weave common in aerospace applications. Fiber orientation is 0/90 degrees and has a fiber/resin ratio of 60/40% by weight (40% max resin content). The laminate is cured under high pressure and at temperatures of nearly 260 degrees F. This fabric and wrapping method gives our components the most strength in the two dimensions that are most important in rocketry; hoop strength and column strength. This fiber configuration also allows a certain degree of flex to make it much more impact resistant.
You may have heard that carbon fiber is very strong but somewhat brittle. That is NOT the case with our airframes and components. The secret is in the type of resin used to bind the carbon filaments, the method of wrapping, and the temperature during cure. We are rocket guys. We know what a rocket goes through in storage, transport, flight, and recovery. We`ve experimented with many resin/fabric combinations to create the perfect balance of strength, rigidity, and impact resistance.
Another bonus......Carbon fiber components are beautiful! Most people wouldn`t paint a carbon fiber rocket. All that`s requires to bring out the beauty of carbon fiber is a nice shiny clear coat. But if you do want to paint it, no problem. The standard finish is 240 grit, sanded.
ULTRA-LIGHT SERIES COMPONENTS
All Ultra-Light Series airframes have a wall thicknesses 0.040" This series is perfect for competitions where very low weight and high strength are top priorities.
Save money by flying Ultra-Light carbon fiber!
"Carbon fiber components cost more than standard components, how would I save money using carbon fiber?"
The savings becomes apparent at launch time. As an example, most 3" diameter rockets require a full G or H motor just to get them off the pad. Using our Ultra-Lite carbon components you can fly a 4" diameter rocket to high altitudes using the same motors! This also means you can fly a huge rocket Pre-Cert or with just a Level 1 cert. Or, if you do want to use larger motors, the Ultra-Lite series allows you to use the long burn motors to achieve much higher altitudes than ever before.
PREMIUM SERIES COMPONENTS
All Premium Series airframes have a wall thicknesses 0.056". This series is perfect for all flight profiles including high thrush, high velocity applications where low weight and super high strength are top priorities.
About the same weight as our phenolic yet stronger as our Glass-Wrapped Phenolic Tubing. High strength combined with great impact resistance makes the airframe tubing an excellent choice for any rocket. Premium Series components are preferred for trans-sonic and super-sonic flight.
The days of the 100+ pound Level 3 rocket are over!
Until now Level 3 rockets were very heavy. The process goes like this: "I want to get my Cert Level 3 using a small M motor. This rocket needs to be strong. To make it strong, it will be heavy. Because it is so heavy, I need to make it stronger. Now it`s even heavier so I better make it stronger..." Before you know it, your rocket won`t fly on that "baby" M you planned to use. The per-launch price just went through the roof! How would you like a Level 3 rocket that you can also fly on a much less expensive L or even K motor? Well now you can!
EXTREME SERIES COMPONENTS
We have no idea why you would ever need an airframe this strong, but maybe you`re crazier that we are! These Extreme Series airframes have a wall thickness of 0.074" and are crazy- strong! Going for record breaking speeds and/or altitudes? These Extreme components are for people that leave nothing to chance.
"Carbon fiber is a super high strength material that is very light weight. It's always the clear winner in any competition."
PML CARBON FIBER COMPONENTS
Public Missiles Ltd. offers a line of airframes, couplers, and nosecones made from the same high-tech aerospace materials and construction techniques you`ve read about in the science and aerospace magazines. Carbon fiber is amazingly strong yet extremely light. Now you can take advantage of the long burn motors as well as the super fast burners!

Tube Cutting & Slotting
PML can slot and cut any of our airframes for you based on your spec. Just let us know what you need done in the text boxes in each item catagory before adding the item to your cart
--- Carbon Fiber Airframes ---
If you need a particular tube cut or slotted, order that tube separately (Quantity 1). Otherwise all tubes will be cut and/or slotted the same way.
--- Carbon Coupler Tubes ---
(use with all airframe types)
If you need a particular coupler tube cut, order that tube separately (Quantity 1). Otherwise all tubes will be cut and/or slotted the same way.
