Multi-effect woven fabric for energy harvesting and heat management
A multi-effect woven fabric for energy harvesting and heat management includes a combination of a predetermined number of yarns woven to each other in a repeating pattern. The yarns include a first yarn for absorbing, storing, and releasing heat energy through a phase change, a second yarn for converting heat energy from a wearer's skin, the first yarn, and a third yarn into far infrared radiation energy and radiating the far infrared radiation energy to other yarns and to the wearer's skin, the third yarn for absorbing moisture from the wearer's skin and/or ambient environment and generating heat energy through an exothermic process, and a fourth yarn with a hydrophobic property. The multi-effect woven fabric maintains a uniform temperature on the wearer's skin by a combination of heat energy generation, heat energy harvesting, and radiation of heat energy.
Flame resistant fabric having wool blends
A flame resistant fabric includes first yarns including inherently flame resistant fibers and second yarns including wool fibers. The fabric may satisfy one or more performance standards set forth in ASTM F 1506-02, NFPA 2112 and NFPA 70E. The fabric may be a knit or woven fabric, such as a plush or terry knit construction, and one or both sides of the fabric may be napped to form a fleece fabric. The second yarns may include wool and modacrylic fibers, or wool fibers and other inherently flame resistant fibers. The first yarns or second yarns may include sufficient inherently flame resistant fibers such that the fabric has a char length of no more than 4 inches and an afterflame of no more than 2 seconds when tested in accordance with ASTM D6413. The fabric may exhibit a thermal shrinkage of no more than 10% when tested in accordance with NFPA 2112.
FABRICATION, APPLICATION AND APPARATUS OF FIBERS WITH ALIGNED POROUS STRUCTURE
Provided is a method of manufacturing fiber with aligned porous structure, an apparatus, and applications of the fiber. The apparatus comprises: a fiber extrusion unit, a freezing unit, and a collection unit for collecting the frozen fibers, wherein fibers extruded from the fiber extrusion unit pass through the freezing unit. Continuous and large scale preparation of such fiber with aligned porous structure is achieved by combining directional freezing and solution spinning.
Woven thermal protection system
A thermal protection system (TPS) for a space vehicle that undergoes partial or full ablation when the TPS is exposed to severe heating during entry into a planetary atmosphere. A first layer includes at least one of carbon, phenolic, silica, alumina and another oxide, low thermal conductivity fibers and yarns connecting two or more first layer sub-layers, is recession-resistant and has reduced porosity. A second layer has a smaller fiber fraction, reduced thermal conductivity and reduced density, and serves as a thermal insulator. The first layer may have partial or full insertion of a resin, or may have a surface densified, recession-resistant sub-layer. Values of a first subset of as many as eight environmental parameters can be used to characterize the space vehicle mission. A second subset of TPS parameters for the system is evaluated to identify whether an ablator system with these TPS values can survive the conditions associated with the first subset of environmental parameters.
THERMALLY INSULATING SUBSTRATE PRODUCT AND METHOD OF MANUFACTURE
This invention relates to a thermally insulating substrate product comprising: a substrate having at least one layer and comprising metallic particles having an average particle size and density selected to block or reflect infrared radiation and aerogel particles having an average pore size and density selected to control conducted and convected thermal energy. The thermally insulating substrate can made as textile and/or film coatings that are light and thin and adapts to external environment conditions for better camouflage as well as improved heat insulation for energy conservation and thermal regulation.
