Towards Toughened Composites: Present and Future Challenge

Dear Colleagues,

Composite materials are characterized by high specific mechanical properties, especially in-plane properties, while their out-of-plane properties have been always a major challenge that limits utilizing the full potential that such material systems can offer. Several design parameters should be addressed in order to enable the spread of the technology even further into industrial applications in areas such as automotive, aerospace, marine transportation, and renewable energy structures. One of the key properties, required in the aforementioned applications, is the toughness of composites materials.

Thus, the aim of the proposed Special Issue is to shed more light on the different but essential toughening mechanisms and techniques of composites. This can be achieved via various approaches including but not limited to: matrix toughening, introduction of nanoparticles or nanotubes, use of thermoplastic veils, and all possible ways of 3D reinforcement such as stitching, tufting, z-pinning, and 3D weaving. The experimental and computational characterization of such relevant toughening mechanisms and their associated failure modes; the proposal of new cost-effective, reliable manufacturing techniques; and non-destructive evaluation of the damage are all key subjects that this Special Issue aims to cover.

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. Materials is an international peer-reviewed open access semimonthly 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.
