Special Issue Information

Dear Colleagues,

Composite materials play a crucial role in, for example, the aerospace, automotive, construction, and marine industries. These materials offer significant advantages, including a high strength-to-weight ratio, excellent corrosion resistance, fatigue durability, thermal stability, and a high temperature resistance. They enable flexible design optimization allowing for the creation of complex structures and the integration of multiple functionalities, thereby providing customized, efficient, and innovative solutions across various sectors. Composite materials are composed of matrix materials reinforced with fibers or particles.

Despite nearing their final form during manufacturing, composite materials require precise secondary processing. Challenges commonly encountered during processing stem from diverse material compositions, leading to issues such as rapid tool wear, uneven cutting forces, and complexity in selecting processing parameters. Mechanical and thermal damage like delamination and ablation are prevalent due to these multifaceted processing methods; they significantly impact the service life and processing efficiency of the final products. Composite materials are considered difficult to process due to their complex structures and anisotropic properties. To address the characteristics and process requirements of different materials, such as fiber orientation and laminated structures, and to ensure quality and performance stability during processing, the theory and technology of ultraprecision machining and non-traditional machining continue to deepen. This is crucial to meet the pressing demands of advanced equipment manufacturing.

In order to advance material processing technologies and expand application areas, this Special Issue aims to help researchers present the latest developments and technologies in the field of composite material processing. The collection will encompass various domains, including theoretical analysis, finite element simulation, and experimental validation.

In the assembly process of aerospace parts, drilling is essential for carbon fiber-reinforced materials. However, due to the extreme thermal sensitivity of these composites, continuous drilling often leads to irreparable defects such as hole wall burns and exit delamination caused by concentrated cutting heat, resulting in the scrapping of parts. To address this issue, this paper explores the impact of temperature characteristics on drilling quality, providing guidance for optimizing the composite drilling process. A simulation model for single and continuous drilling was established to analyze the temperature distribution on the tool surface during drilling. A drilling temperature measurement system based on thin-film thermocouple technology was developed, enabling real-time online temperature monitoring. Continuous drilling experiments were conducted, analyzing the correlation between maximum drilling temperature and hole quality. Results show that temperatures from −25.75 °C to −9.75 °C and from 182 °C to 200.75 °C cause significant exit damage, while optimal hole quality is achieved between −1.25 °C and 168 °C. Full article

Recognizing the lightweight nature and superior tribological properties of Al-based metal matrix composites, this study introduces a novel analytical model based on polynomial approximations, offering new insights into the mechanisms of dry friction in AlSi10Mg-SiC composite materials. Key findings highlight a significant reduction in the coefficient of friction (COF) and oscillation amplitudes in SiC-reinforced composites, indicating superior tribological performance compared to their unreinforced counterparts. This behavior is attributed to the effective distribution of SiC particles within the aluminum matrix, which mitigates the stick–slip motion commonly observed under dry sliding conditions. Importantly, the model using polynomial approximations is noted for its simplicity and ease of implementation in practice. The study’s conclusions not only underscore the benefits of SiC reinforcement in enhancing wear resistance but also contribute to the broader field of materials science by providing a robust framework for the predictive modeling of COF in various composite systems.

Affiliation: Robert Gordon University
Abstract: The demand for composite materials is surging across industries like energy storage, aerospace, automotive, and healthcare, fuelled by their exceptional attributes such as high strength-to-weight ratios and resistance to corrosion. However, machining these materials presents significant challenges due to their heterogeneous and anisotropic structures, leading to complex tool-workpiece interactions, rapid tool wear, poor surface quality, and environmental concerns. This review explores recent advancements in machining techniques for composite materials, with a particular focus on addressing key challenges and leveraging artificial intelligence (AI) solutions. It serves as a comprehensive resource to enhance machining practices in modern composite manufacturing by optimising machining parameters. The paper concludes by pinpointing significant research gaps in hybrid machining and AI-driven strategies, suggesting promising avenues for enhancing high-precision surface machining of fibre-reinforced composites and propel-ling the field forward.
