Special Issue Information

Dear Colleagues,

This Special Issue will focus on the materials science of polymer-based composites utilized in automotive components. It will address the chemistry, structure, properties, and performance of polymeric reinforcements and matrices employed in various vehicle parts (cars, buses, railways, etc.). Significant emphasis will be placed on the incorporation and effects of nanoscale and microscale fillers in enhancing specific functional properties (e.g., mechanical strength, thermal stability, barrier properties, electrical conductivity, flame retardancy).

We invite contributions detailing the processing techniques and conditions crucial for achieving targeted material characteristics essential for diverse automotive applications. Dedicated papers are encouraged on specific component areas such as exterior panels, interior trim, seating structures, brake components, flooring, springs, wheels, and battery enclosures. Research integrating fundamental theoretical models describing structure–property relationships with experimental data is particularly welcome.

This Special Issue is timely, given the automotive industry's challenges, including resource constraints, environmental imperatives, and the need for accelerated material development cycles. It aims to provide a foundational resource for researchers in academia and industry developing next-generation composite materials. The collection will serve as a valuable reference for understanding the materials science principles underpinning advanced automotive composites.

With the global shift towards alternative fuels and electric/hybrid vehicles, discussions on the inherent advantages of lightweight polymeric composites for weight reduction, energy efficiency, and life-cycle sustainability are highly relevant. The potential for novel lightweight composite materials enabling future automotive designs will be explored. Challenges and opportunities from a materials perspective will be discussed in detail. We look forward to receiving your contributions.

The research presented in this work focuses on the structural optimization of a multilayer CFRP (carbon fiber reinforced polymer) laminate integrated within a railway carbody frame. The primary objective is to implement a systematic design methodology aimed at achieving significant mass reduction while preserving the mechanical performance and safety margins required by railway standards. To this end, a multi-stage optimization framework was developed to explore the sensitivity of fiber orientation on the laminate’s failure behavior, directly coupled with high-fidelity finite element models for objective performance extraction. The investigation was initially conducted using an asynchronous optimization strategy, where the orientation of each individual ply was decoupled and analyzed independently. This phase revealed that a tailored, ply-specific approach is essential to address the varying structural requirements across the laminate thickness. Through this methodology, an optimal sequence of 36°/54°/126° was identified, achieving a significant 40.83% reduction in the Tsai–Wu failure index compared to a standard 0°/0°/0° baseline. Subsequently, a synchronous rotation analysis was performed to compare these results against conventional single-orientation design strategies. While the synchronous optimum was identified at 54°, it yielded a lower failure index reduction of 24.81%. The comparison highlights a further 16% performance gain enabled by the asynchronous method. Finally, the validation confirmed that these in-plane improvements were achieved without compromising interlaminar integrity, as the interlaminar shear stress (ILSS) remained constant and safe. This framework provides an objective and rigorous tool for the railway industry, replacing empirical design methods with a high-performance, data-driven approach. Full article
