  • Patent number: 8283266
    Abstract: Methods of making nonwoven mats having good strength after being scored and folded and particularly useful in making lightweight, compressible ceiling panels are disclosed. The mats also have excellent flame resistance. The mats include a blend comprising a major portion of glass fibers and a minor portion of man-made polymer fibers, the fibers being bound together with a cured binder containing a homopolymer or copolymer of polyacrylic acid and a polyol. The binder bonding the mat together can be cured to only a “B” stage to produce thermoformable mats or more fully cured to produce mats having the properties described above.

  • Publication number: 20120251796
    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.

  • Publication number: 20120219464
    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.

  • 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.
