The performance comparison between carbon fiber tubes and metal tubes is roughly as follows:

- Lighter than metal tubes including titanium
- Very low thermal expansion coefficient
- Many times harder than metal pipes
- Times the number of steel reinforcements by weight
- More resistant to corrosion than metal
- Can withstand more load cycles than metal
- Strength directional design
- Carbon fiber has low heat transfer rate

The comparison of specific performance parameters in the above table is only based on the general attribute range and should not be used for specific product design purposes.

The strength and stiffness of carbon fiber pipes is difficult to directly compare to metal pipes because there are many possibilities for fiber orientation during the lay-up of carbon fiber materials, while the strength, stiffness and weight of composite pipes are determined by fiber modulus, fiber orientation/placement and used. But for metal pipes, their performance only depends on the material types and dimensions of the pipe itself, and does not involve directional factors. This is actually a major advantage of carbon fiber tubes over metal tubes. In the table above we have divided the chart to show the properties of the fiber itself as well as the epoxy resin and fiber matrix. This does show the importance of the resin/fiber ratio, as too much resin does cause important problems. The resin/fiber ratio of our pipes has been proven to be optimal over many years.
