Dear Colleagues,

Multi-functional composites and metamaterials have increasingly attracted many scientists and industrialist’s attraction. Many engineering areas such as aeroscope, mechanical, civil, automotive,  construction, and marine have employed this group of materials for various applications recently.  These materials are meant to perform a variety of functions apart from the primary structural function which provides structural enhancement such as strength, stiffness, and stability while non-structural functions provide energy harvesting, self-healing capability, control of wave propagation, and other physical phenomena, sensing and actuation, thermal conductors for efficient heating and cooling a system, and even sometimes as a protective layer, etc. Many of the recent developments focused on multi-functional composites and metamaterials to enable devices that achieve much higher performance and efficiency than conventional offerings. This Special Issue aims to present the latest achievements and comprehensive development,  improvement, characterization, and applications of multi-functional composites and metamaterials in multi-disciplinary fields. The papers published in the Special Issue are expected to present new results and concepts of these structures and materials with a main focus on the gradual transformation of scientific progress into new technologies, which, as a rule, not only have significantly improved characteristics are also safe for human health and the environment.  Generally, topics in the Special Issue include but are not limited to the analytical formulation and different aspects of computational and experimental characterization of this group of novel materials and structures. Industrial-scale case studies, finite element modeling, additive manufacturing studies, nano-scale simulations, and machine learning approaches are also welcome to this issue. 

I cordially invite you to submit your contributions to full papers, communications, and carefully written review papers to this issue. All submitted manuscripts will undergo a rigorous review process and will only consider publications if they meet journal standards.

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. Journal of Composites Science 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 1800 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.
