Abstract

This study presents an integrated approach, combining numerical, and experimental methods, to investigate the mechanical performance of low-carbon steel and polyketone composite plates. Fabricated via hot pressing, these multi-material clad plates were subjected to forming, uniaxial tensile, peel, and lap-shear tests to assess both bulk and interfacial mechanical properties. Detailed microstructural analyses provided insights into the behavior of the interfaces under mechanical stress. Numerical simulations paralleled experimental work, setting a foundation for future studies to explore different configurations and interfacial conditions of such multi-material systems. Integration of a polymer layer significantly enhanced the mechanical properties of the clad, showing an 8.21% increase in specific strength over traditional metallic clads and underscoring potential performance benefits for structural applications. Issues such as delamination and debonding during forming were identified as areas for improvement. The strong correlation between simulation results and experimental data confirms the model’s reliability, making a significant contribution to the development of steel-based clad composites. This research provides crucial insights for the application of steel-polymer composites in sectors such as electric vehicle manufacturing and related structural uses.

钢-聚合物-钢复合材料复合层的失效行为：力学性能和微观组织演变

本文采用数值与实验相结合的方法研究了低碳钢与聚酮复合材料板的力学性能。通过热压制造，这些多材料复合板经受了成形、单轴拉伸、剥离和搭接剪切试验，以评估体积和界面力学性能。详细的微观结构分析提供了对机械应力作用下界面行为的见解。数值模拟与实验工作并行，为进一步研究多材料体系的不同构型和界面条件奠定了基础。聚合物层的集成显著提高了覆层的机械性能，比传统金属覆层的比强度提高了8.21%，并强调了结构应用的潜在性能优势。在成形过程中，分层和脱粘等问题被确定为需要改进的领域。仿真结果与实验数据具有较强的相关性，证实了模型的可靠性，为钢基复合材料的发展做出了重要贡献。这项研究为钢-聚合物复合材料在电动汽车制造和相关结构用途等领域的应用提供了至关重要的见解。图形抽象

期刊介绍： Metals and Materials International publishes original papers and occasional critical reviews on all aspects of research and technology in materials engineering: physical metallurgy, materials science, and processing of metals and other materials. Emphasis is placed on those aspects of the science of materials that are concerned with the relationships among the processing, structure and properties (mechanical, chemical, electrical, electrochemical, magnetic and optical) of materials. Aspects of processing include the melting, casting, and fabrication with the thermodynamics, kinetics and modeling.
