TL;DR: In this article, a shim is disposed between the upper and lower composite panels around a portion of the periphery of the composite sandwich, which is then disposed over an inner layer of foaming adhesive.
Abstract: This invention is directed to a high strength, lightweight honeycomb core composite sandwich panel Typical composite sandwich panels comprise a honeycomb panel disposed between upper and lower composite panels In this invention, a shim is disposed between the upper and lower composite panels around a portion of the periphery of the composite sandwich The shim is disposed over an inner layer of foaming adhesive

Abstract: Honeycomb sandwich structures have been extensively investigated in the past decades. A kind of innovative honeycomb sandwich with ceramic tile (ceramic sandwich), was investigated here for its bending behavior by using finite-element model implemented in Abaqus/Explicit code. In our studies, a series numerical simulations of three-point bending were carried out for the ceramic sandwich and conventional aluminum honeycomb sandwich. Their numerical models were validated by experiments. As confirmed that the ceramic tile largely enhances the stiffness of the structure, which contributes a lot to the promotion of the bending resistance capacity. Parametric studies were performed to further investigate the effects brought from the ceramic tile and honeycomb core in terms of changing the thickness of ceramic tile, the thickness of honeycomb wall, the length of honeycomb cells. It was found that the bending performance heavily relay on the geometric configuration of the present sandwich panel. In addition, the ceramic sandwich with reinforced honeycomb core also shows better mechanical behavior in the simulation. All these achievements provide more likelihood of designing composited high-performance sandwich.

TL;DR: In this paper, the effect of the adhesive joint between the honeycomb core and the face sheets on the load transfer and static response of sandwich panels was examined. But the adhesive joints were not modeled by three-dimensional solid elements.

TL;DR: In this article, the authors measured the underwater blast response of free-standing sandwich plates with a square honeycomb core and a corrugated core, and the total momentum imparted to the sandwich plate and the degree of core compaction were measured as a function of core strength, mass of the front face sheet (that is, the wet face) and time constant of the blast pulse.
