| Abstract Scope |
Aluminum-Carbon Nanotube systems are of great military interest in the field of high performance, lightweight structural materials. Traditional methodologies for fabricating these composites involve wet mixing through solvents or direct wetting of nanotubes with molten aluminum. The work presented in this paper will focus on producing composites using dry powder mixing methods. Mixtures of aluminum and multiwall carbon nanotubes (MWCNTs) were used to produce nanostructured composite powders via high-energy milling. These powders were then consolidated using an instrumented hot isostatic press (HIP), which allows for real-time monitoring of sample densification. This process minimizes the exposure of the nanostructured powder to high temperature, and as a result, the microstructure of the final product can be controlled. Imaging of the consolidated pieces show MWCNTs sandwiched between aluminum lamellae, which is evidence of the retention of the nanostructure imparted during the high-energy milling process. |
