Special Issue Information

Dear Colleagues,

The use of structural composites in high-performance applications (e.g., aerospace, automotive, sports, energy, defense) has increased significantly in recent years driven by the strong need of structure light weighting. The development of new advanced polymeric materials and structural fiber reinforcements have strongly supported the move to light weighting. However, there have several associated challenges, especially with regard to the success of achieving the complex geometrical shapes and features of composite components, as well as reducing the overall cycle time to control the related costs during the processing of composites. 

The major challenges that arise during processing are mainly due to the increased deformation rate and the viscoelastic nature of the resins influencing the cure cycle of polymeric composite materials. Such issues have been actively pursued by world-wide researchers at various size scales, including the fundamental scientific work on applied research at component level in high-performance applications. In this context, property characterization of a wide range of composite materials forms is a key area of research that is directly linked to the quality of composite components. The choice of accurate measurement techniques and correct relevant processing parameters can create a huge difference in the outcome of forming processes. Similarly, the analysis of modified and new forming processes to enhance the rate of production and maintain a consistent quality of components has been a major focus of researchers and academics to generate state-of-the-art knowledge.

The aim of this Special Issue is to provide an adequate platform to researchers to disseminate high-quality recent research findings of experimental, modeling, and simulation work related to forming processes and property characterization of high-performance composites. The Special Issue encompasses a wide variety of research work in terms of structural composite application, material forms and scales, nature of scientific work, technology readiness levels, etc.

Carbon fiber reinforced plastics (CFRP) are widely used in aerospace and new energy vehicles due to their high specific strength and flexible design ability. At present, the traditional forming process of CFRP curved surface components has problems of low mechanical properties and long processing time. In this paper, a new method of hot gas forming was proposed to obtain CFRP components. By applying high temperature and high-pressure gas on one side of CFRP, the material was forced to deform and solidify at the same time. A special device for hot gas forming was designed and developed. The curing behavior and mechanical properties of original CFRP plates were studied. The main defects and the corresponding control methods of hot gas forming parts were analyzed by forming spherical parts, and the feasibility of the hot gas forming process was verified. Taking the battery cover plate of a new energy vehicle as the research object, the influence of forming temperature, gas pressure, pressurization rate and other process parameters on the mechanical properties of complex CFRP components were analyzed. The mechanism of both strength and efficiency improvement was analyzed. The results showed that with the increasing of gas pressure, the tensile strength and forming efficiency of the CFRP curved components were improved obviously. Under reasonable forming parameters, the tensile strength of the obtained parts was increased by 37%, and the forming efficiency was increased by 58%. The fiber bundles were distributed more evenly and compactly under the hot gas forming. This showed that the use of hot gas forming had good potential in the preparation of high-performance CFRP parts, which was helpful to improve the processing efficiency and forming quality of CFRP curved parts in the aerospace and new energy automotive fields.
