Advancing Sustainable Lightweight Structures: The Strategic Role of Reinforcements

About this Research Topic

Background

Reinforcements are pivotal in propelling the evolution of sustainable lightweight structures, dramatically enhancing their structural performance, lifespan, and environmental credentials. This Research Topic is dedicated to uncovering and expanding our understanding of how reinforcements-ranging from advanced fibres to nanomaterials, enable a new generation of eco-conscious, high-performance structures based on fundamental solid and structural mechanics principles

Key Research Themes

1. Optimizing Strength and Structural Integrity

Lightweight matrices, such as polymers and composites, often require reinforcements (e.g., carbon fibers, glass fibers, or engineered nanoparticles) to confer adequate load-bearing capacity. Research submissions are encouraged that address novel reinforcement strategies, mechanisms of load transfer, and multi-scale strengthening effects that replace or outperform heavier traditional materials.

2. Weight Minimization and Material Efficiency

Achieving structural performance with less material is central to sustainability. This theme explores current advances enabling designers to realize robust, load-efficient structures with reduced embodied material through innovative reinforcement architectures, directly impacting resource consumption and logistics.

3. Enhancing Durability and Service Life

Improving longevity is integral to sustainable design. Reinforcements can significantly improve resistance to environmental degradation, moisture, UV exposure, and chemical attack. Contributions exploring durability under real-world conditions or accelerated ageing are welcome, with a focus on lowering the total lifecycle impact.

4. Energy Efficiency and Passive Design Synergies

Lightweight reinforced structures are inherently more energy-efficient in transportation and use. This track welcomes research on integrated design approaches that leverage reinforcements to optimize thermal insulation, reduce energy demands, and facilitate the adoption of energy-generating or energy-saving systems.

5. Innovative Design and Architectural Freedom

Reinforcements not only enhance performance but also unlock new design possibilities. Submissions showcasing how reinforcement strategies enable creative geometries, complex forms, or multifunctional structures, without compromising sustainability, are particularly encouraged.

6. Environmental and Circular Economy Impacts

The right choice and application of reinforcements can drastically cut a structure’s carbon footprint, especially through reductions in primary material use and transport. Studies addressing recyclability, end-of-life solutions, and life cycle assessment (LCA) of reinforced lightweight systems are essential for advancing circularity and resource efficiency.

7. Economic Viability and Life Cycle Costing

While the upfront investment in advanced reinforcements may be significant, reductions in operational, maintenance, and logistical costs often yield a positive long-term return. Submissions focusing on comprehensive economic analyses, incentives for sustainable investment, and cost optimization frameworks are sought.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

  In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?

  Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.
