Dear Colleagues,

Composites are multiphase or hybrid materials which, when combined, display noticeably different properties from conventional materials. Nanocomposites with metallic, ceramic, or polymeric matrices reinforced by nanoparticles have been the subject of intense research. These nanocomposites show significant improvements in various properties, exceeding the values of composites containing micron-scale reinforcements.

The greatest challenges facing the development of nanocomposites for wide application are the cost and availability of nanoscale reinforcements and the complexity of the synthesis and processing methods of these nanocomposites. As with conventional composites, the properties of nanocomposites are strongly dependent on the properties of the reinforcement material, their distribution and volume fraction, as well as the interfacial bond between the reinforcement and the matrix.

Carbon nanotubes, due to their extraordinary properties, are excellent candidates for use as reinforcements in nanocomposites. Interest in research on this subject continues since the expected promising results of these nanocomposites have not yet been obtained due to several challenges that need to be overcome.

The main challenges in this field are the development of cost-effective production techniques that provide a dense and homogeneous dispersion of reinforcement through the matrix and lead to a strong interfacial bond between the matrix and the reinforcement.

This Special Issue aims to publish research papers and reviews that cover recent developments on the production, characterization, and properties of “Metal Matrix Composites Reinforced with Carbon Nanotubes”, as well as their potential in future applications.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Metals is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
