Many industries use honeycomb composites extensively, including the aerospace, automotive, furniture, packaging, and logistic sectors. A specific type of composite material known as a sandwich is created by joining two stiff but thin skins to lightweight dense core. The strong bending stiffness overall low density are made possible core material's larger thickness despite its typical strength. ...

In this paper, the bending performances of sandwich panels with corrugated triangular, honeycomb, aluminum foam, pyramidal truss, double sine (DSC), and 3D re-entrant auxetic cores are assessed compared, both experimentally numerically. Three-point experiments were performed on corrugated, truss core identical face-sheets height. The experimental numerical results compared well for honeycomb co...

Abstract Sandwich panels’ exceptional mechanical properties and low density, owing to their multifunctional characteristics innovative design, made them a popular choice in numerous industries. panels with cellular cores are known for energy absorption properties, which make effective absorbers high-impact scenarios such as accidents or explosions. For advancing research on sandwich panels, it ...
