碳纳米管的直接纺丝产生具有明显令人鼓舞的机械性能的纤维。虽然最好的强度（2.2 N/tex）和刚度（160 N/tex）有望与已建立的碳纤维竞争，但断裂时吸收的最大能量（46 J/g）略高。纤维由非常长的双壁纳米管组成，其直径惊人地大（在5-10 nm范围内），其塌陷以给出狗骨横截面。
The direct spinning of carbon nanotubes yields fibres with distinctly encouraging mechanical properties. While the best strength (2.2 N/tex) and stiffness (160 N/tex) promise competition for established carbon fibres, the maximum energy absorbed at fracture (46 J/g) is somewhat higher. The fibres consist of very long double-walled nanotubes of surprisingly large diameter (in the 5-10 nm range), which collapse to give a dog-bone cross section.
