Carbon Fiber airframes and components are available for advanced amateur and professional applications.
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 that can propel your rockets to much higher altitudes than the fast burners!
PML carbon fiber components are not filament wound. They are convolute 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. The laminate is cured under high pressure and at temperatures of nearly 160 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 little wet sanding and a nice shiny clear coat. But if you do want to paint it, no problem. The standard finish is 150 grit, sanded. Feel free to mix and match components from the 4 different series below to get the perfect balance of weight and strength required for your particular project. HOWEVER, BE AWARE THAT THE COMPONENTS ON THIS PAGE DO **NOT** FIT OTHER PML PRODUCTS (Example: our FNC-6.0 does not fit the 6 inch carbon fiber tubing on this page, or vice versa.)

PML has offered `glass-wrapped phenolic tubes (FGPTs, on the Airframes Page) for many years. These are used for Level 3 and Mach+ flights. Many people have indicated that they would rather wrap their own tubes using the same fiberglass and carbon fiber fabrics we use. Now you can! PML is proud to introduce our customers to a variety of fiberglass and carbon fiber fabrics for just about every purpose. With these fabrics you can wrap your own tubes, make nosecones, molds and many other structural items. The fabrics are compatible with most if not all industrial and hobby epoxies and adhesives.
Check back to this page often as we will be adding many new items. In the very near future we will be releasing a line of carbon fiber components including airframes, nosecones, and other items.
