Microscopic analysis of metal matrix composites containing carbon Nanomaterials

Abstract

Metallic matrix composites reinforced with carbon nanomaterials continue to attract interest because of their excellent mechanical, thermal, and electrical properties. However, two critical issues have limited their commercialization. Uniform distribution of carbon nanomaterials in metallic matrices is difficult, and the interfaces between the nanomaterials and matrices are weak. Microscope-based analysis was recently used to quantitatively examine these microstructural features and investigate their contributions to the composites' mechanical, thermal, and electrical properties. The impacts of the microstructure on these properties are discussed in the first section of this review. In the second section, the various microscopic techniques used to study the distribution of carbon nanomaterials in metallic matrices and their interfaces are described.

“…BAHL and BAGHA [19] used 2D FE analysis to study the interfacial effects between the reinforcements and the metal matrix and reported that the cohesive layer behaved the same as the matrix before damage. KIM et al [20] analyzed various interface techniques and microstructure analyses to study their effect on the material properties of the MMCs. MAURYA et al [21] reviewed the reinforcements that are usually added to the Aluminum MMCs.…”
