Abstract:
An inorganic fiber containing silica and magnesia as the major fiber components and which further includes an intended chromium oxide additive to improve the dimensional stability of the fiber. The inorganic fiber exhibits good thermal insulation performance at 1400°C and greater, retains mechanical integrity after exposure to the use temperature, and which remains soluble in physiological fluids. Also provided are thermal insulation product forms that are made from a plurality of the inorganic fibers, methods of preparing the inorganic fiber, and methods of thermally insulating articles using thermal insulation prepared from a plurality of the inorganic fibers.
Abstract:
The invention relates to a shading device (10) for a greenhouse (15), with a shading element (20) and at least one lighting element (50,50'), wherein the shading element (20) comprises an outer side (21) and an inner side (22), the shading element (20) is formed from interwoven electrically conductive first thread elements (30,30') and electrically insulating second thread elements (40), the first thread element (30,30') comprises a reflective mean (33), reflecting an ambient light (60), the lighting element (50,50') is arranged at the inner side (22) of the shading element (20) and connected with the first thread element (30,30'), and the lighting element (50,50') is driven by an electrical current, conducted by the first thread element (30,30'), resulting in the emission of an artificial light (51), illuminating a plant (80) growing in the greenhouse (15).
Abstract:
A woven preform used to reinforce a composite structure which includes a central portion (6,10) having a plurality of interwoven layers. The preform also includes first and second end portions (4,12) having a plurality of independent woven layers (50) that are integrally woven with the plurality o interwoven layers in the central portion (6,10) and which extend along the entire length the preform. Interspersed between the plurality of independent woven layers (50) in the first and second end portions are bias plies (26). The first and second end portions can have through thickness reinforcements (71) comprising reinforcement fibers that traverse through the independent woven layers and the bias plies, locking them together.
Abstract:
This invention provides free-standing structures, functionalized free-standing structures and functional devices that are flexible, including nano- and micromachined flexible fabrics comprising woven networks and mesh networks. The present invention provides processing methods for making and functionalizing flexible free-standing structures having a wide range of integrated materials, devices and device components. The methods of the present invention are capable of providing large area functional electronic, optoelectronic, fluidic, and electromechanical devices and device arrays which exhibit good device performance in stretched, bent and/or deformed configurations.
Abstract:
A fabric comprising a textile layer comprising yarns, wherein said textile layer is permeable to water vapour and impermeable to liquid water; and disposed on at least part of one side of the textile layer is a wicking means.
Abstract:
An article having a superhydrophobic or oleophobic ceramic polymer composite surface is formed by the coating of the surface with a fluid comprising a polymer, copolymer, or polymer precursor and a plurality of glass, ceramic, or ceramic-polymer particles. The particles have fluorinated surfaces and at least a portion of the polymer's repeating units that are fluorinated or perfluorinated. The composite can be a cross-linked polymer.
Abstract:
A web for reinforcing the wall of a vessel or conduit having a concave surface, and methods of installation therein, is disclosed. The web includes an elongated composite laminate having a fabric layer with a plurality of fibers embedded into a cured resin matrix. When cured on a curing surface, the composite laminate retains an elastic memory of the curing surface such that the composite laminate is substantially self-supporting against the inside surface of the vessel. In use, a tack coat is applied to at least a portion of the bottom side of the laminate, which is then applied to the inside surface of the wall. Multiple such composites may be applied to the wall in turn in a ring pattern or in a spiral pattern, overlapping at least one recently applied composite to form a water-tight seal within and reinforce the conduit.
