Special Issue Information

Dear Colleagues,

Under the macro-control of the "double carbon" policy, the research and application of material recycling technology and new lightweight materials are imminent. There is an urgent need to solve the technical difficulties that are a general concern in the process of automotive lightweighting technology and industrialisation. Lightweight materials often have different physical and chemical properties from conventional steel and require special machining and joining processes. For example, the forming and cutting of carbon fibre composites require high-precision equipment and complex process control, while the welding of aluminium alloys is prone to defects such as porosity and cracks. In addition, lightweight design requires comprehensive consideration of many aspects of vehicle safety, comfort, and durability. How to achieve multi-objective optimisation in lightweight design is another difficulty in lightweight technology research. A solution to these pain points requires interdisciplinary cooperation and innovation, including joint efforts in a number of fields such as materials science, manufacturing processes, and design optimisation.

The scope of this Call for Papers includes, but is not limited to, the following topics:

  • Design and property control of high-strength and high-toughness materials;
  • Design and property control of light alloy materials;
  • Research and application of integrated design methodology of microstructures, materials, and processes;
  • Research on cooperative optimal design methodology for ultra-large structural/functional topology;
  • Optimisation of structural parameters driven by deep learning augmented agent models;
  • A high-precision simulation method for the integrated manufacturing process of ultra-large components;
  • Power battery system and body integration design method;
  • Design and manufacture of high-strength steel integrated double door rings;
  • Design and manufacture of ultra-large complex thin-walled structural die castings;
  • Integrated design and manufacturing of composite structure automotive components.

Carbon–Kevlar hybrid composites are being increasingly recognized as suitable materials for aerospace, automotive, and construction applications due to their unique combination of strength, toughness, and safety. Prior to their use, extensive testing and validation are essential to ensure that these composites meet the specific safety and performance standards required by each industry. In this study, the mechanical performance and behavior of five different types of Carbon–Kevlar hybrid composites were investigated. In addition to microstructural investigations, mechanical tests were also carried out, including tensile, bending, impact, and micro-hardness tests. The investigated composites were Carbon–Kevlar hybrids without orientation, with a symmetrical orientation, and with the addition of TiO2 nanoparticles at weight percentages of 3%, 4%, and 5%. The results showed that the mechanical properties of these composites could be significantly influenced by different fiber orientations and the addition of TiO2 nanoparticles. In particular, the addition of TiO2 nanoparticles increased the tensile strength, hardness, toughness, and breaking strength. Of the composites tested, the composite reinforced with 5% TiO2 nanoparticles exhibited the highest mechanical performance, with a 79.8 Shore D hardness, 406 MPa tensile strength, 398 N/mm2 flexural strength, and 10.1 J impact energy. These results indicate that Carbon–Kevlar hybrid composites reinforced with TiO2 nanoparticles have excellent mechanical properties that make them highly suitable for armor plating, helmets, and vehicle armoring in particular and a wide range of other industrial applications in general.
