Pultruded Carbon Fiber Tubes - Maximum Rigidity with Minimum Mass
Pultruded Carbon Fiber Tubes are manufactured for maximum rigidity with minimum mass. Pultrusion orients the fibers lengthwise down the shaft for maximum structural rigidity. Carbon fiber contributes to the rigidity while minimizing weight. Carbon is 70% lighter than steel, 40% lighter than aluminum, and three times the stiffness of either for the same weight.
Carbon fiber has a negative coefficient of thermal expansion, meaning it expands as the temperature lowers. The resin matrix, on the other hand, has a positive coefficient. The net result is virtually no expansion or contraction of the composite over a wide range of temperatures.
Pultruded carbon fiber tube is the ultimate push rod since it contains 95% unidirectional carbon fiber running longitudinally and is covered with a light glass scrim. This design offers a high stiffness-to-weight ratio and makes this tube ideal for 1/4 scale aircraft pushrods, slope soarer, and helicopter tail booms, as well as reinforcement rods in lightweight constructions such as model cars, musical instruments, trade show presentations, etc.
