Special Issue Information

Dear Colleagues,

The past few decades have seen outstanding advances in the use of composite materials in the aerospace industry. Composites have revolutionized traditional design concepts and made possible an unparalleled range of new and exciting viable materials for aircraft structures.

This Special Issue, titled "Advanced Aircraft Composite Structure Design", focuses on the latest advancements and cutting-edge research that contribute to knowledge in the use of composite materials in aircraft structures. Original research papers and review articles dealing with design, research, and development studies, experimental investigations, theoretical analysis, and fabrication techniques relevant to the application of composites, ranging from individual components such as plates to complete composite structures, are welcome.

By bringing together advancements in the development, characterization, and application of composite materials, this Special Issue aims to disseminate knowledge between users, manufacturers, engineers, and researchers involved in aircraft component manufacturing using composite materials.

Composite hat-stiffened panels are widely used in civil aircraft structural design as typical closed-section stiffened components with high load-carrying efficiency. To accurately predict the post-buckling bearing capacity and optimize the tapered termination design of such panels, this paper investigates the failure process of composite hat-stiffened panels with tapered ends through physical modeling and numerical analysis. A nonlinear failure analysis model is established by introducing the failure mechanisms of adhesive interfaces and composite laminates. The modeling method is verified against experimental results, showing discrepancies of 2.7% for buckling load and 3.5% for post-buckling failure load, respectively. Based on the validated numerical approach, parametric studies are carried out to analyze the effects of termination taper parameters on buckling and post-buckling mechanical behaviors. The results indicate that the termination taper design effectively adjusts the stiffness matching between stiffeners and skin and relieves local stress concentration. The optimal taper angle of 120° is recommended, where the failure load increases by 22% to 141.8 kN compared to the baseline configuration, significantly improving its post-buckling load-carrying capacity. The findings of this study can provide technical references for the design of stiffened composite panels with tapered stringer terminations in aerospace engineering. Full article

Two-dimensional C/SiC are promising candidates for use in high-temperature structures in aeroengines and thermal protection systems in the aerospace industry, which will be subjected to loads in various directions during service. In this paper, the in-plane tensile, compressive, and shear mechanical properties of 2D C/SiC were investigated over a strain-rate range of 10−5 s−1 to 10 s−1. The failure mechanisms of the material under different loading conditions were analyzed. The study reveals that 2D C/SiC exhibits nonlinear stress–strain relationships under tension and shear, while it displays a linear stress–strain relationship under compression similar to the quasi-static loading state. The strain-rate strengthening effect is most pronounced under compression, whereas the effect is less significant under tensile loading. The reason for the observed increase in strength is the additional energy consumed by multiple crack initiation and propagation. A rate-dependent constitutive model was fitted, which agrees well with the experimental data for both tensile and shear loading conditions. Full article
