Special Issue "Composites for Wind Energy Applications"
A special issue of Materials (ISSN 1996-1944).
Deadline for manuscript submissions: closed (31 December 2017)
The drastic expansion of the renewable energy sector is an important precondition for reducing fossil fuel dependency and preventing global warming. Europe seeks to achieve 20% electricity supply from renewable sources by 2020, increasing offshore wind energy capacity by 21% annually. Such an increase in wind energy generation can be realized practically by installing parks from large and extra-large wind turbines off-shore.
The requirements for wind turbine materials are very strict, far stricter than those for automotive and aerospace materials. While a car can be easily repaired at the nearest service station, and airplane materials can be rather expensive, a wind turbine must be cheap (to ensure competitiveness against common energy sources) and sustain 20 or more years of work without failure (due to the very high costs of offshore repair). Due to such extremal requirements, the development of wind turbine materials represents the forefront of composite development.
Wind turbine blades should sustain a combination of extreme mechanical and cyclic multiaxial loading of variable amplitudes, with environmental and thermal/high humidity/erosion effects. This leads to unexpected failures, with resulting downtimes, loss of revenue, increased operational and maintenance costs, with view of the decreased accessibility of off-shore parks.
Currently, most widely-used composites for wind turbine blades are glass fiber/epoxy composites, while investigations using carbon, aramid and basalt fibers, thermoplastics polymers, and bio-based and nanoengineered materials are under way, and also have the potential of yielding practical applications in the long run.
In this Special Issue, recent works and state-of-the-art overviews on the development, modelling, properties, and manufacturing of composites for wind turbines are presented.
We invite prospective authors to submit their manuscripts for this Special Issue. Full papers, communications, and reviews are all welcome.

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 papers will be 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. Materials 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 1600 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.
