  • 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.

  • Patent number: 11193845
    Abstract: The present invention relates to an ultrahigh sensitive pressure-sensing film based on spiky hollow carbon spheres and the fabrication method thereof. The fabricated spiky hollow carbon spheres composed polydimethylsiloxane sensing film whose spheres were well dispersed in the matrix. The spiky structure is useful for the spheres to trigger Fowler-Nordheim (F-N) tunneling effect and thus enhancing the sensitivity of the material. The carbon material fabricated by the precursor transformation method contains a proper Nitrogen doping, which has efficiently increased the carrier migration ability. The hollow structure can both regulate the density of fillers and help to improve its temperature independence. Calcine the spheres under an inert atmosphere to transform the spiky hollow organic spheres into a carbon one, in this process the Nitrogen fraction and graphitization can be adjusted. The above carbon spheres then can be assembled with polydimethylsiloxane to achieve the composite film.
