  • Patent number: 10724163
    Abstract: A fabric of nanofibers that includes an adhesive is described. The nanofibers can be twisted or both twisted and coiled prior to formation into a fabric. The adhesive can be selectively applied to or infiltrated within portions of the nanofibers comprising the nanofiber fabric. The adhesive enables connection of the nanofiber fabric to an underlying substrate, even in cases in which the underlying substrate has a three-dimensional topography, while the selective location of the adhesive on the fabric limits the contact area between the adhesive and the nanofibers of the nanofiber fabric. This limited contact area can help preserve the beneficial properties of the nanofibers (e.g., thermal conductivity, electrical conductivity, infra-red (IR) radiation transparency) that otherwise might be degraded by the presence of adhesive.

  • Patent number: 10301769
    Abstract: An axially stretchable fiber-reinforced composite material, comprising an elastically deformable matrix having a low modulus of elasticity, and a fabric core encapsulated by the matrix. The core comprises first fibers interlaced with second fibers, with the first fibers being in a non-parallel orientation relative to the material's longitudinal axis, and the second fibers are non-parallel relative to the first fibers when the composite material is in a retracted position. The composite material is stretchable between the retracted and extended positions. The fibers have a high modulus of elasticity. The composite material has a non-linear modulus relative to elongation of the composite material between the retraced and extended positions. Movement of the material toward the extended position causes the first and second fibers to rotate relative to each other and in a direction toward alignment with the longitudinal axis, and the matrix material biases the composite material toward the retracted position.
