The uses of square composite tubing are as limitless as your imagination. Our shaped tubes are perfect for designs where "clocking" is important. Standard dimensions allow you to use standard components. Carbon fiber filament. Carbon fiber filament is made up of carbon atoms organized into a crystalline structure. Because of its very high stiffness and strength, it is widely used in the aerospace and automotive industries. It has one of the highest strength-to-weight ratios in existence — higher than both steel and titanium.

The negative Poisson’s ratio effects of the CFRP 3D DAH auxetic metamaterials are analytically studied by the energy method. 3D finite element models based on Modal The damping ratio is dependent on the amplitude as a result of the random orientation of CNTs in the epoxy matrix. The natural frequency shows negligible influence on the damping properties. The forced vibration test indicates that the damping ratios of the CFRP composites increase with increasing CNT content in both the 1st and 2nd vibration modes.
