Fig. 11 shows the fractographs of the composites at differentball-millingtimes. Although thecompositefabricated with 2 hball-millinghad lots of CNT clusters (Figs. 3a and 5a), no obvious holes were observed on the fracture surface (Fig. 11a), and the fracture surface was characterized by small dimples and large tear ridges (Fig. 11b).

Production Methods for Carbon Nanotubes Including Arc

Ball millingand subsequent annealing is a simple method for the production of CNTs. Although it is well established that mechanical attrition of this type can lead to fully nano porous microstructures, it was not until a few years ago that CNTs of carbon and boron nitride were produced from these powders by thermal annealing.
