A multilayer thermal insulation panel for construction and manufacturing method thereof are described. A manufacturing method of a backing layer of a multilayer thermal insulation panel for construction, the method comprising the steps of: providing a reinforcement layer in fibrous material, spreading a first fluid mineral mixture on the reinforcement layer to form a cladding layer of the reinforcement layer; forming a fire-resistant layer comprising expansive graphite on the cladding layer; and drying the backing layer.

The present invention generally relates to the printing of materials, using 3-dimensional printing and other printing techniques, including the use of one or more mixing nozzles, and/or multi-axis control over the translation and/or rotation of the print head or the substrate onto which materials are printed. In some embodiments, a material may be prepared by extruding material through print head comprising a nozzle, such as a microfluidic printing nozzle, which may be used to mix materials within the nozzle and direct the resulting product onto a substrate. The print head and/or the substrate may be configured to be translated and/or rotated, for example, using a computer or other controller, in order to control the deposition of material onto the substrate.

A foam article, such as a cushioning element for an article of footwear, apparel or sporting equipment is provided that comprises a foam component, such as a midsole, having a number of beneficial physical characteristics. The cushioning element is a low-density foamed component with a surface skin that encases the remaining foam volume. The cushioning element has a number of foam volumes, arranged to achieve a more consistent foam component. Additionally, the cushioning element includes a series of concentric ridges extending radially outwardly from injection gate vestige locations, and a number of striation bands near the perimeter of the cushioning element. The location of the gate vestiges can be beneficially arranged to produce intersecting flow boundaries that are located away from key strain areas of the cushioning element. The cushioning element is more environmentally-friendly, requiring less energy to produce while still providing acceptable energy return and low density.

A method for producing a single-layer waterbar, use of a single-layer extruded profile as a waterbar, a method for sealing an internal or an external joint between two sections of concrete, and sealed construction; wherein the production method includes extruding a melt-processed starting composition through an extruder die to form an extruded profile, wherein the starting composition includes 35-75 wt.-% of at least one polymer and 25-65 wt.-% of at least one solid particulate filler.

A method for producing bone grafts using 3-D printing is employed using a 3-D image of a graft location to produce a 3-D model of the graft. This is printed using a 3-D printer and a printing medium that produces a porous, biocompatible, biodegradable material that is conducive to osteoinduction. For example, the printing medium may be PCL, PLLA, PGLA, or another approved biocompatible polymer. In addition such a method may be useful for cosmetic surgeries, reconstructive surgeries, and various techniques required by such procedures. Once the graft is placed, natural bone gradually replaces the graft.

Porous and microporous parts prepared by additive manufacturing as disclosed herein are useful in medical and non-medical applications. The parts are prepared from a composition containing both a solvent soluble component and a solvent insoluble component. After a part is printed by an additive manufacturing process it is exposed to solvent to extract solvent soluble component away from the printed part, resulting in a part having surface cavities.

A cushion having a fibrous foam architecture. The cushion has a trim cover and a number of fibrous layers attached to the trim cover. One or more structural properties of a fibrous layer can be controlled to differ from that of other layers.

The present invention discloses a foaming and dyeing integrated production line for a polymer material product, and a method thereof. The production line comprises a foaming and dyeing kettle, a pressure control module, a dye separation module, a fluid liquefaction and storage module, a fluid pressurization delivery module, a fluid heating module and a dyeing circulation module. The production line integrates the functions of one-step foaming and supercritical fluid dyeing of polymer material, thereby being simple in structure, comprehensive in function, convenient to operate, high in production efficiency, good in product quality and low in cost; besides, the production line can carry out both dyeing and foaming operations, only foaming operation or only dyeing operation on polymer material.

A method for the design, manufacture, and assembly of modular lattice structures composed of cuboctahedron unit cells.

An in-situ hydrophobically modified aramid nano aerogel fiber as well as a preparation method and uses thereof are provided. The preparation method includes: providing an aramid nano spinning solution; preparing a hydrophobically modified aramid nano aerogel fiber by using a spinning technology, wherein the coagulating bath adopted by the spinning technology includes a first organic solvent and a halogenated reagent including a monochloroalkane, a monochloroalkane, a dibromoalkane, a dichloroalkane and a trichloroalkane; and then drying to obtain the in-situ hydrophobically modified aramid nano aerogel fiber. The in-situ hydrophobically modified aramid nano aerogel fiber has a unique three-dimensional porous network structure, low heat conductivity, high porosity, high tensile strength and elongation at break, a certain spinnability and structure stability, and can be applied to the field of textiles. A fabric knitted with the hydrophobic fibers has a self-cleaning ability.
