A method of redefining an opening in a composite component comprises filling the opening with a filling material, where the opening is defined in a body of the composite component and opens onto a surface defined by the composite component, and redefining the opening such that the opening extends into the body. Some methods comprise removing an existing coating from the surface of the composite component prior to filling the opening with the filling material and applying a new coating to the surface prior to redefining the opening such that the opening extends through the new coating and into the body. An exemplary composite component comprises a body, a surface with a coating thereon, an original opening defined through the body and filled with a filling material, and a new opening defined through the coating into the body, which may be defined at a new location from the original opening.

The application discloses a high-whiteness MGO substrate, a preparation method thereof and a decorative board having the substrate. The high-whiteness MGO substrate includes a surface layer and a substrate, wherein the substrate is prepared from a forming agent, a lightweight filler, a modifier and water in parts by mass as follows: 40-49 parts of light burned magnesium oxide powder, 18-25 parts of magnesium sulfate heptahydrate, 16-25 parts of a polyvinyl alcohol solution, 16-20 parts of a plant powder, and 0.5-2 parts of a modifier; the modifier being obtained by mixing citric acid, phosphoric acid, and sodium sulfate in a mass ratio of 10:3:6.

A manufacturing method is disclosed herein. The method includes arranging a preform with a plurality of clamping assemblies, the plurality of clamping assemblies disposed along ends of the preform; and forming the preform into a shaped body, the forming including: incrementally tensioning the preform around a surface of an inner mold line using the plurality of clamping assemblies; and drawing the preform into a set of forming beads of the inner mold line.

An intermediate member is a member which is directly or indirectly sandwiched between a first object and a second object. The intermediate member includes a plate-like supporting member having a lower surface which is one main surface opposed to the first object and a plurality of ceramic blocks fixed on an upper surface which is the other main surface of the supporting member in a state of being separated from one another. Thus, in a state where the plurality of ceramic blocks are collectively held by the supporting member having relatively high shape retention, by disposing the intermediate member between the objects, it is possible to easily arrange the plurality of ceramic blocks between the objects with high positioning accuracy.

Various methods and assemblies are provided for producing composite components having formed in features. For example, a method may comprise depositing a composite material on a base tool; bringing a feature forming tool into contact with the composite material; and processing the composite material with the feature forming tool in contact with the composite material. The processed composite material forms a green state composite component. The feature forming tool comprises a sheet having one or more elements for interacting with one or more elements of the base tool to form one or more features of the composite component. In some embodiments, the method also may comprise sealing a bag around the feature forming tool and the composite material after bringing the tool into contact with the composite material and removing the bag and the feature forming tool from the green state composite component after processing.

A method for manufacturing a thermoelectric material is provided. According to the method, a first shaped body is formed from a thermoelectric powder, of which a crystal has a layer structure. An extruded body is formed by extruding the first shaped body. A plurality of cut-off pieces are formed by cutting the extruded body along a cross-section perpendicular to an extrusion direction. A second shaped body is formed by stacking and pressing the cut-off pieces along a direction perpendicular to the extrusion direction. According to the above, a thermoelectric ability of a thermoelectric material and an efficiency for manufacturing a thermoelectric module may be improved.

A manufacturing method is provided. A preform is arranged over a surface of an inner mold line. The preform is folded over sides of the inner mold line. An end of the preform is pressed into a grip strip coupled to a side of the inner mold line. The grip strip is translated in a first direction to tension the preform into a shaped body.

A manufacturing method is disclosed herein. The method includes arranging a preform with a plurality of clamping assemblies, the plurality of clamping assemblies disposed along ends of the preform; and forming the preform into a shaped body, the forming including incrementally tensioning the preform around a surface of an inner mold line using the plurality of clamping assemblies; and drawing the preform into a set of forming beads of the inner mold line.

A housing for a portable electronic device includes a radio frequency transparent polycrystalline ceramic portion comprising a first surface and a second surface parallel to the first surface. The radio frequency transparent polycrystalline ceramic portion comprises a macro-texture on at least a portion of the first surface, and a predetermined micro-texture is disposed on at least a portion of the macro-texture. A method for manufacturing a housing for a portable electronic device includes forming a green ceramic article comprising a first surface and a second surface parallel to the first surface, embossing at least a portion of the first surface of the green ceramic article with a macro-texture, and sintering the green ceramic article comprising the macro-texture to form a sintered ceramic article. A predetermined micro-texture is disposed on at least a portion of the macro-texture.
