Aluminum has few mechanical strength and high ductility because it has many
sliding planes. Its low mechanical resistance excludes it for use in structural
applications, but alloyed with other metals can improve its mechanical
properties. Since its discovery by Ijima in 1991, carbon nanotubes (NTCs) have
been considered an ideal reinforcement material to enhance the mechanical
properties of materials in both polymers, ceramics, and metals, in which one of
the principal goals is to obtain materials light but with high resistance. In the
development of metal matrix composite materials, carbon nanotubes have
emerged as ideal nano-scale reinforcers due to their significant aspect ratios,
Youngs modulus, tensile strength, and chemical stability, as well as their low
density. In this investigation, an Al-4% Mg weight composite material was
synthesized, reinforced with 0.5% weight of NTCs, previously synthesized by the
pyrolysis spray method, purified using an acid solution and dispersed in an
amino trimethyl phosphonic acid solution. The NTCs were dispersed in the
metallic matrix using planetary mechanical milling. With a ratio RWP 10:1 for a
permanence time of 2 hours. The results obtained show that. It is possible to
have a homogeneous dispersion in the matrix without the formation of
agglomerates, in the same way, the aspect ratio of the reinforcing material can
maintain.
