Special Issue Information

Dear Colleagues,

Mechanical components and structures made of thermoset and thermoplastic polymer materials with various types of fiber reinforcements are being increasingly employed in aerospace, mechanical, transportation, green energy, and infrastructure engineering. Fibers of glass, carbon, aramid, and other stiffer and stronger materials in both discontinuous and continuous forms are now being utilized as reinforcements at the nano and micro level to achieve superior mechanical properties, durability, and high performance. The present Special Issue focuses on recent developments in (a) the characterization of mechanical and material behaviour at the nano, micro, meso, and macro levels of composite materials using experimental, analytical, and computational methods and techniques, and (b) design approaches using deterministic and probabilistic methodologies for components and structures comprising such materials. This Special Issue welcomes the submission of research focusing on tensile, compressive, shear, fracture, fatigue, creep, impact, and damping properties, as well as the durability and degradation of such materials, components and structures due to temperature and moisture. This also includes studies on nanocomposites involving the atomistic, molecular, and computational modeling of continuum mechanics, experimental investigations, and hybrid approaches. The application of these materials in machine tools, machine elements, mechanical structures, aerospace structures, automobile components, naval vessels, helicopter blades and rotors, and infrastructure will be of interest to this Special Issue.

This paper examines the mechanical performance of fibre-reinforced composite sandwich structures (FRPSSs) for maritime applications, focusing on the impact bending and damage sequence after seawater exposure. Glass-fibre/epoxy facesheets with various PVC foam core configurations underwent low-velocity single and multiple impacts. An in situ moisture-uptake methodology monitored moisture ingress until saturation. Results showed moisture uptake reduced impact bending capacity and bending stiffness to varying degrees. While energy-absorption performance remained largely unchanged under single impacts, significant differences were noted for multiple impacts. Failure analysis confirmed the reductions in some damage modes such as facesheet fracture, indentation, and core shear failures, while core shearing, delamination, core/facesheet debonding, and fibre breakage were identified as the main failure modes. These insights enhance understanding and optimisation of FRPSSs for improved out-of-plane damage resistance in marine applications. Full article
