TL;DR: In this article, the free vibration analysis of composite sandwich cylindrical shell with a flexible core using a higher order sandwich panel theory is presented. But the analysis is restricted to the case of composite shells.

TL;DR: In this article, an ant colony optimisation (ACO) algorithm was used to search a design space that was defined by sandwich theory and a material database in order to identify constructions that were optimal with respect to low mass and low cost.

10 Jul 1998TL;DR: In this paper, a honeycomb core was obtained from a woven fabric prepreg with a cover factor of 95% or more and a small porosity in the skin panels fabricated by the cured prepreg and has excellent surface smoothness with few pits and depressions.
Abstract: A woven fabric prepreg comprising at least [A] a woven fabric as reinforcing fibers, [B] a thermosetting resin or thermosetting resin composition and [C] fine particles of a resin and having a cover factor of 95% or more, and a honeycomb sandwich panel, comprising skin panels fabricated by said woven fabric prepreg and [D] a honeycomb core can be obtained. The woven fabric prepreg little changes in tackiness with the lapse of time and has moderate drapability, being excellent in self adhesiveness to the honeycomb core when used as skin panels of a honeycomb sandwich panel. Furthermore, the honeycomb sandwich panel obtained has a small porosity in the skin panels fabricated by the cured prepreg and has excellent surface smoothness with few pits and depressions on the surfaces of the skin panels.

TL;DR: In this article, the authors employ finite element analysis (FEA) to derive equivalent stiffness properties of sandwich structures with various types of cores, different from conventional continuum cores and honeycomb core.

TL;DR: In this paper, a prefabricated concrete sandwich panel, with insulating material acting as a structural layer able to transfer the shear stresses, is discussed, using an in-pressure casting technique.
