TL;DR: In this paper, a lightweight C/SiC pyramidal core lattice sandwich panel was proposed and fabricated for potential applications as hot structure and thermal protection system (TPS), and the heat transfer characteristics of the lattice were measured from 600 to 1150°C through an aerodynamic heating simulation experimental system.

TL;DR: In this paper, a method of installing an insert in a sandwich panel for mounting a fastener includes making a hole in the panel and inserting a spacer having a height greater than the thickness of the panel.
Abstract: A method of installing an insert in a sandwich panel for mounting a fastener includes making a hole in the panel and inserting a spacer having a height greater than the thickness of the panel. An entrance rim of the spacer extends above an upper surface of the panel and a setting tool exerts a force on the entrance rim to force it into the hole and to position an upper edge of the entrance rim flush with the panel surface. The spacer can include an annular groove on an interior wall of the entrance rim to facilitate the cold working deformation during an installation in the panel and a hole engaging surface to align and maintain the spacer within the hole. An outer exterior surface of the entrance rim can be indented and coated with a first sealing compound to ensure a watertight seal with the panel. A second sealant material can be provided within the entrance rim for sealing with a head of any fastener extending through the spacer. An improved floor panel with spacer is accordingly provided for aircraft.

TL;DR: In this paper, a continuum model for evaluating partially composite insulated concrete sandwich panel deflections with discrete shear connectors due to differential volume changes such as those caused by differences in temperature between the wythes is evaluated.
Abstract: A continuum model for evaluating partially composite insulated concrete sandwich panel deflections with discrete shear connectors due to differential volume changes such as those caused by differences in temperature between the wythes is evaluated for accuracy by comparison with finite-element analysis. Design equations for computing these deflections are provided. Analysis of sample panels indicates that the continuum model provides acceptable accuracy for calculating thermal bowing of wall panels. The resulting equations show that, for long panels, the amount of thermal bowing in the panels is relatively insensitive to the stiffness of the connectors. This implies that long insulated sandwich panels with low connecting-layer stiffness will experience nearly the same amount of thermal bowing as fully composite panels.

TL;DR: In this article, an extension of the 1,2-order plate theory to a higher order {3,2} theory is presented, where the displacement components at any point on the plate are approximated in terms of weighted-average quantities (displacements and rotations) that are functions of the inplane coordinates.
