TL;DR: In this article, the authors present experimental studies on the quasi-static indentation of a rigid indenter into sandwich panels with carbon fibre-reinforced polymer face and polymeric foam core and find that both nose shape and foam core density have large influence on the indentation response of the sandwich panels in terms of absorbed energy, indentation at failure and damage area.
Abstract: This paper presents experimental studies on the quasi-static indentation of a rigid indenter into sandwich panels with carbon fibre-reinforced polymer face and polymeric foam core. It was found that both nose shape and foam core density have large influence on the indentation response of the sandwich panels in terms of absorbed energy, indentation at failure and damage area. A dependency of the indentation load on the supporting condition was observed. It was also found that the difference in indentation resistance between the sandwich panel and its corresponding core material depends on the core density.

TL;DR: In this article, the displacement and stress in a functionally graded core for a one-dimensionalsandwichplate and compares them to that in a uniform core are presented. And the authors demonstrate the signiµ cant reduction in shear stresses at the face-sheet-core interface in the sandwich panel achieved by functionally grading the core properties.
Abstract: Introduction W EIGHT savingsofferedby sandwich constructionsfor structures that require high bending stiffness are signi cant. However, sandwich constructions have not been fully exploited in structuralapplicationsdue to damage toleranceconcerns.The core– face-sheet delamination is a major concern in sandwich construction. The stiffness discontinuityat the face sheet and core interface results in a large increase in shear stresses. Although the core material itself may be able to withstand very high shear stresses, the bond (or adhesive layer) at the interface could be relativelyweaker resulting in interfacial delamination. Results from this study indicate that the interfacial shear stresses can be reduced by varying (functionallygrading) the core properties through the thickness. This Note presents the displacement and stress elds in a functionallygraded core for a one-dimensionalsandwichplate and compares them to that in a uniformcore. The objective is to demonstrate the signi cant reduction in shear stresses at the face-sheet–core interface in the sandwich panel achieved by functionally grading the core properties.

TL;DR: In this paper, a method for rapid fabrication and prototyping of low-density carbon fiber sandwich panel cores based on laser beam cutting (LBC) was presented, where lattice core constructions with oblique and vertical strut morphologies were fabricated from two fiber orientation architectures.
