A Carbon Fibre Rod suitable for a range of applications including modelling and prototyping. The rod exhibits amazing dimensional precision and light weight. Telescopic action can be achieved by matching the diameter of the rod with a tube with the corresponding inner diameter.
This carbon fibre rod (available in a range of sizes) is ultra strong & light, and great for general modelmaking, robotics, prototyping and RC hobbyists. The very small diameters (<3mm) have a reasonable amount of flex (not much, especially in short lengths) whereas the larger diameters I imagine are extremely stiff.
