TL;DR: In this article, two foam-filling schemes were applied to strengthen the woven lattice truss sandwich panel (WLTSP), which can effectively restrain the flexural and shear deformation of the fiber pillars in the woven core and increase the flatwise compression resistance.
Abstract: Woven lattice truss sandwich panel (WLTSP) is a novel lightweight multifunctional construction material. To further improve its compression strength and bending resistance, two foam-filling schemes were applied to strengthen the WLTSP. Flatwise compression and three-point bending experiments were performed to reveal the deformation, the failure, the energy absorption, and the foam-filling effect. The results show that foam-filling methods can effectively restrain the flexural and shear deformation of the fiber pillars in the woven-core and increase the flatwise compression resistance of the WLTSP. Foam-filling scheme can effectively increase the flexure ductility and failure load through enhancing the shear and indentation resistances of truss core of the WLTSP. All experiments reveal that the foam-filled woven lattice truss could effectively improve the crashworthiness of the WLTSP. Concrete foam can increase the total energy absorption (EA) but reduce the specific energy absorption (SEA). Polyurethane foam is a much better core-filling material to improve the crashworthiness of WLTSPs.

TL;DR: In this paper, the authors proposed a honeycomb sandwich panel for noise control, which is designed to maintain a sub-sonic bending wave speed in the sandwich panel over as great a frequency range as possible.
Abstract: Honeycomb sandwich panels which have similar mechanical properties can have significantly different acoustic properties. The mechanical properties are panel thickness, static bending stiffness and mass per unit area of the panel. The acoustic performance of the panel can be assessed by considering the panel as either a primary radiator of structure borne noise or as a transmission loss barrier. The differences in acoustic performance of the sandwich panels is determined by the bending wave speed characteristic of the panel. The key to designing honeycomb panels for noise control is to maintain a sub-sonic bending wave speed in the sandwich panel over as great a frequency range as possible. The noise control benefits of a properly designed nomex honeycomb sandwich panel are demonstrated relative to alternative non-optimum designs.

TL;DR: In this paper, a nonlinear explicit dynamic finite element (FE) model using ABAQUS was developed, which can study both the panels' static behavior under typical flexural loading and dynamic behavior under blast loading.
