Special Issue Information

Dear Colleagues,

The engineering landscape is being reshaped by advanced composite materials, which are pivotal in enabling lightweight, durable, and high-performance structures across critical sectors such as the aerospace, automotive, marine, defense, and construction industries. The performance of these structures is inherently governed by the intricate relationship between their internal architecture and their resultant mechanical properties.

This Special Issue seeks to compile cutting-edge research and review articles that deepen our understanding of this critical structure–property relationship. We encourage submissions that investigate key mechanical responses and failure mechanisms, including but not limited to strength, fatigue, impact resistance, and buckling instability. Furthermore, we are particularly interested in recent advances in optimization methods and AI-driven design for enhancing composite performance, such as layout optimization, configuration optimization, and machine learning-based prediction of mechanical behavior.

The primary aim is to create a valuable resource for researchers and engineers, fostering the development of next-generation composites with tailored mechanical performance for demanding applications.

Carbon-fiber-reinforced thermoset polyimide composites have found wide applications in various aerospace areas. In this paper, the influence of carbon-fiber sizing on the thermal properties of polyimide composites was studied. Nonlinear detriment of the epoxy sizing was found to affect the composite’s thermal resistance. Furtherly, the mechanism, possibly responsible for the nonlinear detrimental effect of the epoxy sizing, was investigated through curing kinetics analysis and chemical structure characterization. Thermal curing activation energy change was found, possibly arising from the insertion of a flexible segment into the polyimide chain by epoxy–amine reaction. Based on the proposed mechanism, a strategy to manipulate the thermal resistance was established and verified. By the precuring of the carbon-fiber sizing, the polyimide composite exhibited obvious thermal resistance improvement, indicated by an enhancement of the glass transition temperature by 20 °C, and a weight-loss reduction under thermal aging at 400 °C by 25%. Simultaneously, a good fiber-matrix interface was maintained. This strategy provides a new route to enhance the thermal properties of polyimide composites from the viewpoint of carbon-fiber-matrix compatibility. Full article
