    Abstract: A fibrous insulation product with improved thermal resistance and method of making it are provided. A plurality of base fibers (e.g. glass) are formed into an insulation product, which may be bindered or unbonded. At least one infrared opacifying agent, such as soot, carbon black or graphite, is applied to the fibrous insulation product such that the base fibers are substantially uniformly coated with opacifying agent. The opacifying agent may be applied, for example, from a fluid suspension or by pulling the fiber through a sooty flame. When opacifying agent applied via a suspension and a binder is desired, it is preferable to avoid binder dispersions that can dislocate the opacifying agent. Alternative binder applications may include co-mingling of base fibers with binder fibers, or other physical or mechanical distributions.

    Abstract: There is provided an inorganic fiber formed article in which the thickness and the surface density can be easily controlled and which has excellent workability and handleability and prevents the deterioration of the work environment when the inorganic fiber formed article is processed for applications, e.g., a heat insulator or a mat. The inorganic fiber formed article includes a mat-like aggregate of inorganic fibers, the inorganic fiber formed article being subjected to needling treatment. The needling density of a surface of the mat exceeds 50 punches/cm2. One or more of requirements (1) to (3) described below is satisfied. (1) The ratio of the number NA of fiber bundles to the number NB of fiber bundles, i.e., NA/NB, is 0.5 or less, the fiber bundles extending in the thickness direction and being observed in regions with a predetermined width W of section A in the longitudinal direction and section B in the transverse direction.

    Abstract: A sliding contact surface-forming material includes a reinforcing base impregnated with a resol-type phenolic resin having polytetrafluoroethylene resin dispersed therein. The reinforcing base is composed of a woven fabric formed by using, respectively as the warp and the weft, a ply yarn which is formed by paralleling at least two strands of a single twist yarn spun from fluorine-containing resin fiber and a single twist yarn spun from polyphenylene sulfide fiber, and by twisting them in the direction opposite to the direction in which the single twist yarns were spun. Also, a multi-layered sliding contact component having the overall shape of a flat plate or a circular cylinder includes the sliding contact surface-forming material so as to configure at least the sliding-contact surface thereof.

  • Publication number: 20120149268
    Abstract: The treatment of textile articles, such as sleeves made of mineral fibers of the type that are used with automotive exhaust system components, by impregnating the textile articles with treatment compositions of various formulations including fluoropolymers and/or mixtures of fluoropolymers with co-resins, followed by heat treatment to cure the compositions, thereby providing protection against impact damage to the sleeve. The treatment serves to impart enhanced resistance to damage of the sleeve by holding the overall fibrous structure of the sleeve together during impact such as by stone impingement, even if underlying fibers themselves are broken or damaged.

  • Patent number: 8148276
    Abstract: A three-dimensional composite reinforcement, a three-dimensionally reinforced multifunctional nanocomposite, and methods of manufacture of each are disclosed. The three dimensional reinforcement comprises a two dimensional fiber cloth upon which carbon nanotubes have been grown, approximately perpendicular to the plane of the fiber cloth. The nanocomposite comprises the three-dimensional reinforcement and a surrounding matrix material. Examples illustrate improvements in the through-thickness mechanical, thermal, and electrical properties of the nanocomposite, in addition to substantial improvements in geometrical stability upon temperature changes and vibrational damping, compared to baseline composites reinforced with the two-dimensional fiber cloth alone.

  • Publication number: 20110306255
    Abstract: The invention relates to a composition including an acid-stable inorganic binder and fibres. The composition includes at least one inorganic binder and fibres, wherein the inorganic binder comprises water glass, the fraction of the composition which is attributable to water glass preferably being in the range from 2% to 99% by weight or 6% to 94% by weight or 11% to 89% by weight or 21% to 79% by weight. The fibre material is present as a weave and/or knit and/or scrim and/or net and/or brous nonwoven web and/or as hollow fibres. Owing to its high strength coupled with low weight, this material of construction is very useful for fabricating ready-made components for structural and civil engineering. In addition, it is also very easy to produce structural components and engineered structures on site. It is possible to realize very light components, to achieve very delicate geometries and, owing to the favourable strength-to-weight ratio, to build unusually high structures.
