    Abstract: Embodiments of the present invention relate to flame resistant fabrics formed with inherently flame resistant fibers that provide the requisite thermal and arc protection, that have improved comfort, and that, in some embodiments, are less expensive than other fabrics formed with inherently flame resistant fibers. Improved comfort and lower cost can be achieved by predominantly locating the inherently flame resistant fibers on the front face of the fabric to impart the requisite thermal and arc protection and predominantly locating the more comfortable (and less expensive) fibers on the back face of the fabric positioned next to the wearer. In this way, overall protection of the fabric is maintained while improving comfort. Some embodiments of such fabrics may also achieve NFPA 70E PPE Category 2 protection.

  • Patent number: 11848449
    Abstract: An electrode active layer is disclosed that includes a network of high aspect ratio carbon elements (e.g., carbon nanotubes, carbon nanotube bundles, graphene flakes, or the like) that provides a highly electrically conductive scaffold that entangles or enmeshes the active material, thereby supporting the layer. A surface treatment can be applied to the high aspect ratio carbon elements to promote adhesion to the active material and any underlying electrode layers improving the overall cohesion and mechanical stability of the active layer. This surface treatment forms only a thin (in some cases even monomolecular) layer on the network, leaving the large void spaces that are free of any bulk binder material and so may instead be filled with active material. The resulting active layer may be formed with excellent mechanical stability even at large thickness and high active material mass loading.

  • Patent number: 11840028
    Abstract: The present invention generally relates to fiber-reinforced composites, including carbon-fiber composites. These materials are useful in load-bearing components for mechanical systems, and other applications. Surprisingly, the carbon fibers can be aligned using an applied magnetic field applied directly to the carbon fibers, rather than to magnetic materials that are used to indirectly align the carbon fibers. For example, the carbon fibers may exhibit an anisotropic diamagnetic response in response to a magnetic field, which can be used to align the fibers. In some cases, the carbon fibers may be relatively pure, and/or have a relatively high modulus, which may result in diamagnetic properties. Other embodiments are generally directed to systems and methods for making or using such composites, kits involving such composites, or the like.

    Abstract: A composite article includes a lightning strike protection coating on a composite substrate. The lightning strike protection coating is formed from electrically conductive material and includes protrusions spaced along the length and width of a portion of the substrate surface. To form the lightning strike protection coating, a form is pressed against electrically conductive coating material on the composite substrate while the electrically conductive coating material is flowable. For example, the form can be a release film used in a composite vacuum bagging process. Suitable release film can have depressions along an inner surface that define an imprint of the coating protrusions. After curing, the coating can be covered with a layer of paint that conceals the protrusions but still allows lightning streamers to penetrate the paint at the protrusions.

  • Patent number: 11557765
    Abstract: An electrode active layer is disclosed that includes a network of high aspect ratio carbon elements (e.g., carbon nanotubes, carbon nanotube bundles, graphene flakes, or the like) that provides a highly electrically conductive scaffold that entangles or enmeshes the active material, thereby supporting the layer. A surface treatment can be applied to the high aspect ratio carbon elements to promote adhesion to the active material and any underlying electrode layers improving the overall cohesion and mechanical stability of the active layer. This surface treatment forms only a thin (in some cases even monomolecular) layer on the network, leaving the large void spaces that are free of any bulk binder material and so may instead be filled with active material. The resulting active layer may be formed with excellent mechanical stability even at large thickness and high active material mass loading.

  • Patent number: 11473222
    Abstract: A copper ion-complexed poly gamma-glutamic acid (?-PGA)/chitosan (CS)/cotton blended antibacterial knitted fabric and a preparation method includes chitosan that is crosslinked with poly gamma-glutamic acid, then a copper-ammonia complex ion solution is added to prepare a spinning solution. The spinning solution is wet spun and then stretched, washed with water, finished, washed with water, and dried to get copper ion-complexed poly gamma-glutamic acid/chitosan composite fibers. The blended antibacterial knitted fabric is then prepared by using cotton fiber yarns and the composite fibers. There is a very high coordination coefficient between carboxyl groups of gamma-PGA and amino groups of CS, so the structure is stable. Poly-gamma glutamic acid can be used as water-retaining agent and heavy metal ion adsorbent, which can increase the loading rate of copper ions.

  • Patent number: 11446883
    Abstract: A method of manufacturing a cured composite structure includes placing a radius filler element into a radius cavity extending along a length of a composite base member formed of dry fiber material comprised of reinforcing fibers. The radius filler element is formed of a radius filler material. The method also includes infusing resin into the dry fiber material, and chemically reacting the resin with the radius filler material to create a mixture of resin and radius filler material along side surface interfaces between the radius filler element and the composite base member. The method additionally includes curing or solidifying the resin, and allowing solvent in the resin to evaporate causing hardening of the mixture and bonding of the radius filler element to the composite base member, and resulting in a cured composite structure.

  • Patent number: 11446915
    Abstract: An improved method for manufacturing a continuous self-healing barrier film is provided. The method includes slot-die coating opposing sides of a separator substrate with a curing agent slurry and a curable resin slurry using a single-sided coating line or a tandem coating line. The method also includes sequentially interleaving inner and outer protective layers via a continuous roll-to-roll process to create a multi-layered barrier film. The barrier film can optionally be formed into a barrier envelope, and an insulating core material can be inserted into the barrier envelope to define an enclosure. Evacuating and sealing the enclosure along a perimeter of the barrier envelop forms a self-healing vacuum insulation panel with excellent properties for use as a building material and in refrigeration systems, for example. The barrier film can alternatively be used in the manufacture of tires, roofing, cargo containers, food packaging, and pharmaceutical packaging, for example.
