Special Issue Information

Dear Colleagues,

Over the past few decades, high performance and multi-functional polymer composites have become the most versatile materials in the automotive industry. Thanks to their low weight and designable properties, polymer composites improve the efficiency of the automobile in terms of lower fuel consumption and carbon emission. The composite modification of inorganic materials, natural fibres, one-dimensional materials and polymers has further expanded the application field of polymer composites in automotive components. With the increasing requirements of high properties, long servicing life and high efficiency, the design, synthesis, modification, processing and recycling of polymer composites are facing great challenges. Developing advanced polymer composite technologies to meet the new requirements is an urgent issue. Therefore, we propose to set up a Special Issue titled “Advances in Polymer Composites for Automotives” to publish articles on the design, forming processes and industrial application of advanced polymer composites, so as to provide a centralized communication platform for relevant researchers and promote their application.

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. Polymers 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 2700 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.

In the present research, coaxial one-side resistance spot welding was performed to join Al5052 and CFRP sheets with different welding currents. The mechanical performance of the cross-lap joint was clarified experimentally. The cross-section of the welded joint and the fracture surfaces was subjected to multi-scale characterization. The fracture behaviours and mechanisms of cross-lap joints are discussed in detail. The results showed that the thermal degradation of CFRP was detected on the cross-section under a 6000 A welding current and the O element was enriched in the decomposed area. The joining zone could be divided into four subregions according to their morphology, which were defined, from outside to inside, as the squeezed zone, the adhesion zone, the cohesion zone and the decomposed zone. After welding, the O-C=O bond disappeared on the CFRP surface while the O=C-N bond was detected on the Al5052 surface. The cross-lap joints demonstrated brittle and ductile fracture behaviours in a cross-tension test, which included two sub-modes: brittle-transition mode and ductile-degradation mode. The transformation of failure modes had a relationship with the heat input and corresponding joining zone composition. The maximum cross-tension load was about 1279 ± 40 N with a welding current of 5600 A. Full article
