对单壁富勒烯纳米管沿管轴方向排列的碳纤维的理论杨氏模数进行了估算。在无限长的管子的极限下，纤维可以具有与钻石相当的杨氏模数。利用纳米管纤维的这一特性，我们研究了一种由层状纳米管纤维和金刚石组成的新型碳复合材料。这种复合材料被发现是一种高模数、低密度的材料，对剪切和其他变形相当稳定。
Theoretical Young's moduli have been estimated for carbon fibers composed of single-walled fullerene nanotubules aligned in the direction of the tubule axis. In the limit of infinitely long tubules, the fibers can have a Young's modulus comparable to that of diamond. Exploiting this property of nanotubule fibers, we investigate a new carbon composite composed of layered nanotubule fibers and diamond. Such a composite is found to be a high-modulus, low-density material that is quite stable to shear and other distortions.
