Carbon
nanotube reinforced aluminum (Al) composites were produced by hot-press
and hot-extrusion methods. The interfacial structure between the carbon
nanotube and Al was examined using a transmission electron microscope
(TEM) and the mechanical properties were measured by a tensile test.
TEM observations have shown that the nanotubes in the composites are not
damaged during the composite preparation and that no reaction products at
the nanotube/Al interface are visible after annealing for 24 h at 983
K. The strength of the composites is only slightly affected by the
annealing time at 873 K, while that of the pure Al produced in a similar
powder metallurgy process significantly decreases with time. These studies
are considered to yield experimental information valuable for producing
high performance composites.
