Summary

Composite materials have garnered significant attention in various industries due to their lightweight nature, high specific stiffness and strength, and tailored mechanical properties. There are many issues that need to be addressed in the analysis and application of aircraft structure design, such as manufacturing processes, deformation, failure, fracture and life problems, etc.

The Special Issue aims to provide an overview of the latest innovations related to structure, design and mechanism of flight composite materials. Contributions range from new theories and formulations to analyses and novel applications. Emphasis is placed on design and mechanics aspects at the flight composite materials and structures. The Issue focuses on experimental, numerical, and analytical studies on different aspects of flight composite materials and their applications.

This Special Issue is devoted to original research and review papers on key topics related to flight composite materials and structures. Topics of interest include but are not limited to design of new composite materials and structures (metamaterial, toughening composites, electromagnetic shielding and electro-thermal functional composites, etc.), standard and non-standard experimental methodologies (tensile, compressive, bending, shear, delamination, impact, fatigue, crash, vibration, etc.), study on mechanism, fracture and damage (damage characterisation and modelling), applications of numerical techniques for advanced modelling, multiscale modelling, structural optimisation methods for lightweight design of flight composite structures.

    Abstract In this work, a comprehensive numerical study of the low-velocity impact (LVI) behavior of QUAD laminates vs. Double-Double (DD) stacking sequences has been performed. Finite element models were drawn, and analyses carried out in Abaqus/Explicit employing continuum shell elements (SC8R) for the plies, cohesive elements (COH3D8) for the delamination interfaces, and the built-in Hashin damage criterion for intralaminar failure. Two different impact energies (50 and 100 J) were applied using a hemispherical impactor mass of 6.25 kg, and the impact histories were investigated in force-time, displacement-time, and energy-absorption responses. The QUAD layup provided the stiffest… More >
