  • Publication number: 20240057305
    Abstract: An electromagnetic wave shielding material includes a metal layer for ground connection provided as an outermost layer of a laminate; wherein only one surface of the metal layer for ground connection is laminated on the insulating layer via the adhesive layer, and assuming d1 is a thickness and ?1 is a Young's modulus of the adhesive layer on the one surface, d2 is a thickness and ?2 is a Young's modulus of the metal layer for ground connection, and ?3 is a composite Young's modulus of the adhesive layer on the one surface and the metal layer for ground connection, the following relational expression is satisfied: ?3/?2>0.60; in which, ?3=?1 (d1/(d1+d2))+?2 (d2 (d1+d2)).

  • Patent number: 11608593
    Abstract: An object of the present invention is to further improve upon the strength and durability of a wire rope. A wire rope has a core rope made of steel; a covering layer, which is made of a composite resin, covering the outer peripheral surface of the core rope; and multiple side strands, which are made of steel, wound on the outer peripheral surface of the core rope covered with the covering layer. The composite resin constituting the covering layer is obtained by blending cellulose nanofibers with polypropylene serving as a matrix.

  • Publication number: 20200157738
    Abstract: A high-strength fiber bundle sufficiently impregnated with a thermoplastic resin, without impairing mechanical strength. A high-strength fiber composite cable is produced by impregnating a bundle of carbon fibers with a matrix resin. The matrix resin is obtained by mixing, with a thermoplastic resin, such as polyphenylene sulfide, an oligomer having a weight-average molecular weight of less than 10,000, obtained by causing a reaction between an organic compound having a phenolic hydroxyl group and an organic compound having a glycidyl ether group. The matrix resin, which has a viscosity low in comparison with that of the thermoplastic resin serving as a base material, readily impregnates the bundle of carbon fibers with certainty.

  • Patent number: 5069944
    Abstract: A thermal transfer record sheet comprising a substrate sheet and a dye receptive layer and a non-tacky layer in this order on at least one surface of the substrate sheet; the dye receptive layer being composed of a crosslinking reaction product of a composition comprising (A-1) a saturated polyester containing units derived from 2,2-bis(4-hydroxyphenyl)propane in the main chain of the polyester and having a glass transition temperature of at least 60.degree. C. and (A-2) a polyisocyanate compound, and the non-tacky layer (B-1) comprising a water-insoluble or sparingly water-soluble fluorine-containing surface-active agent and (B-2) having a thickness of 50 to 200 angstrom.
