Carbon nanotube (CNT) materials have excellent mechanical, thermal, and electrical properties that make them interesting for their potential applications in the electronics and aerospace industries. In particular, carbon nanotube paper (CNP)/polymer composites are potential candidates for lightweight multi-functional structural materials with high mechanical performances. CNP can be fabricated by filtering aqueous suspensions of CNT. We confirm that carbon aqueous dispersion can be manufactured using ultrasonication. Our results showed dramatic improvements in electrical conductivity with a percolation threshold ~0.2% of CNT. By significantly improving the dispersion of CNT, we showed that only a very small amount of CNTs were needed to achieve the conductivity levels required for different electrical applications. In addition, we demonstrated that the aqueous dispersion of carbon fiber (CF) could be achieved using an ozone treatment; we also determined that CNT/CF paper could be fabricated by the wet laying of mixed CNT/CF aqueous dispersion as well. CNT/CF papers were embedded in epoxy resin by a resin infusion process to realize CNT/Epoxy composites. We also addressed the electrical conductivity measurements of CNT/CF paper as well as the mechanical properties of the paper and their polymer composites.
