Metal Matrix Composite: Fabrication Technology, Mechanical Properties, and Applications

Dear Colleagues,

The modern science of composite materials was born in the 1960s after Tony Kelly published his fundamental results obtained by experimenting with metal matrix composites (MMCs). At the same time, Bill Watt and colleagues invented the process of producing carbon fibres, which were almost an ideal component for a composite after being held together by a polymeric binder. Since that time, carbon fibre reinforced plastics (CFRPs) have become major materials for aerospace applications replacing metal alloys in some structures and significantly contributing to an advance in their characteristics. In fact, this was necessary because metal alloys were approaching their physical limits and could not be a base for the further essential perfecting of some products. To date, MMCs have been in the shadow of CFRPs because, first, CFRPs are cheaper as a result of cheaper fabrication technologies and, second, their usage allows many crucial problems to be solved. Today, CFRPs are matured materials; their present grade is rather similar to that of metal alloys a half a century ago. Therefore, further vital perfecting of some machines is impossible without an improvement in the properties of structural materials. This can be achieved by using MMCs that combine the best properties of metal alloys and CFRP. This Special Issue of Metals aims to help material scientists and engineers to determine the present state-of-the-art of metal matrix composites and materials for the future.

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.
