Review on advances in porous Al composites and the possible way forward
Porous aluminum (Al) composites are lightweight and high-strength materials composing of Al as a matrix material with some strengthening reinforcements and pore-forming agents that result in the formation of new material with superior physical properties and energy absorption capacities.

| Summary: | Porous aluminum (Al) composites are lightweight and high-strength materials composing
of Al as a matrix material with some strengthening reinforcements and pore-forming
agents that result in the formation of new material with superior physical properties
and energy absorption capacities. This work gives an overview of the porous Al-foams
developed thus far, including the foaming agents and space holders, their properties,
production techniques, and applications. First, it deliberates the foaming agents and space
holders responsible for the foaming and formation of pores in the composites followed by
the mechanical properties of the foams. Al has huge potential for applications that require
lightweight, high-strength, and high-energy absorption capacity materials, especially in
structural construction and automobile manufacturing. Although Al-foams have been
successfully used in automobiles for crashworthiness, lightweight structure, and other
functional applications, the development of Al foams with enhanced characteristics and
properties has limitations. This review discusses various reinforcements used for
improving the characteristics of Al-foams. This review also provides an overview of various
commercial foams and their contribution to several applications. Finally, it attempts to
reveal impediments in foam production with suggested solutions for overcoming the
problems in this area. |
