Fabrication and characterization of aligned CNT/C composites
Source abstract
Abstract
Long aligned carbon nanotube (ACNT) arrays over 4 mm thick were prepared by chemical vapor deposition by adjusting processing parameters. ACNT/C composites were fabricated by densifying the ACNTs with chemical vapor infiltration, and were characterized by SEM, PLM, XRD, TGA and Raman spectroscopy. It was found that the pyrocarbon was mainly of the rough lamella type for ACNT/C composites compared with the typically smooth lamella type for traditional carbon/carbon (C/C) composites, in spite of using the same process. Pyrocabon around CNTs showed a high degree of crystallization. The temperature at which ACNT/C composites began to show a weight loss in air was about 50 ℃ higher than that for C/C composites.
