A method of partially insulating an interior space of a pre-formed fluted core panel is disclosed herein. The fluted core panel includes a first facesheet, a second facesheet spaced apart from the first facesheet, and webs between the first facesheet and second facesheet. The interior space is defined between the first facesheet, the second facesheet, and adjacent webs. The method includes positioning a spacer in a first portion of the interior space, positioning a membrane between the spacer and a second portion of the interior space, and positioning insulation in the second portion of the interior space. Additionally, the method includes pressing the membrane against the spacer, curing the membrane, and removing the spacer from the first portion of the interior space.

A method of layerwise solid freeform fabrication is disclosed. The method comprises, for each of at least a few of the layers, dispensing and hardening at least a first modeling material and a second modeling material to form a core region and one or more envelope regions at least partially surrounding the core region. In some embodiments, the ratio between the elastic moduli of adjacent regions, when hardened, is from about 1 to about 20.

Provided are a porous structure and a method of fabricating the same. The porous structure may include an aluminum oxide containing at least one of fluorine and phenyl group. For example, the porous structure may be formed from alumina which contains fluorine or phenyl group. The method of fabricating the porous structure may include preparing an aluminum precursor including at least one of fluorine and phenyl group; providing a precursor solution by mixing the precursor with a solvent; and forming the porous structure having 3-dimensional network structure including the aluminum oxide containing the at least one of fluorine and phenyl group from the precursor solution through gelation.

The biodegradable composite insulation material is made from date palm leaf fibers and powdered okra. The date palm leaf fibers have a concentration of between 50 wt % and 90 wt % of the biodegradable composite insulation material, and the powdered okra has a concentration of between 10 wt % and 50 wt % of the biodegradable composite insulation material. The biodegradable composite insulation material is prepared by mixing date palm leaf fibers and powdered okra, in the above concentrations, to form a mixture. This mixture is then wetted with water, added to a mold, and heated under pressure to form a compressed article. The compressed article is then dried to form the biodegradable composite insulation material.

A method for forming a vacuum insulated structure using a prepared core material includes preparing a powder insulation material defining a bulk density, pre-densifying the powder insulation material to form a pre-densified insulation base, crushing the pre-densified insulation base into granular core insulation to define a core density of the granular core insulation, disposing the granular core insulation having the core density into an insulating cavity defined within an insulating structure and expressing gas from the interior cavity of the insulating structure to further densify the granular core insulation to define a target density. The granular core insulation defines the target density disposed within the insulating structure defines the vacuum insulation structure, wherein the target density defines a density in the range of from approximately 80 grams per liter to approximately 350 grams per liter.

A method of manufacturing a hybrid insulating panel includes providing a mold of a frame, dispensing a first foam material in a liquid phase in the mold, and placing a beam in the mold. The method includes curing the first foam material to form an integrated frame, in which the integrated frame includes the beam at least partially surrounded by the first foam. Further, the method includes dispensing a second foam material into a panel cavity to form a panel body. The panel cavity is at least partially defined by a side of the integrated frame. The method includes curing the second foam material to form a panel body, wherein the panel body is secured to the integrated frame.
