Carbon Fiber airframes and components are available for advanced amateur and professional applications.
All new, completely re-engineered carbon fiber components!
We`ve spent the last year redesigning and building new equipment and molds to bring you the highest quality components on the market with super fast turn-arount times. The entire manufacturing process has been updated and the sizes have been tweaked to closely match our other products. We also added some new nosecone shapes in both carbon and glass (in case you need RF transparency for you NC mounted payload).
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 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 little wet sanding and a nice shiny clear coat. But if you do want to paint it, no problem. The standard finish is 180 grit, sanded.
