  • Patent number: 7823355
    Abstract: A nonmetallic masonry flashing is disclosed. The flashing includes a laminate that is applicable to cavity walls and particularly masonry block walls. The flashing has an adhesive layer which is a pressure activated, hot melt adhesive with various additives. The additives provide reinforcement to the entire structure and uses fiber glass or filamentous fragments of polypropylene. These additives are admixed into the hot melt adhesive. The nonmetallic masonry flashing employs peel-and-stick technology. After removal of a release sheet, the adhesive layer is pressed against the rough surface of the masonry block. The pressure activation creates a durable bond with the masonry block. Incorporated into the nonmetallic masonry flashing are various high-strength, polymeric laminates. The high-strength of the polymeric laminates is derived from advances in cross-lamination and laminates having a scrim as a core component.

  • Patent number: 7678977
    Abstract: There is provided a repetition lever for a grand piano, which is excellent in shape retainability and dimensional stability and is light in weight and high in rigidity, thereby enabling required operations to be stably performed and improving the capability of repeated key striking. A repetition lever 4 for a grand piano, which performs the operation of pushing up a hammer 30 after the hammer has struck a string, is formed by a molded article of a thermoplastic resin containing long fibers for reinforcement, the molded article being molded by a long fiber process. The repetition lever 4 has reduced cross-sectional area portions 49, 50, and 54 for reducing weight thereof. The long fibers for reinforcement are carbon fibers, and the thermoplastic resin is an ABS resin.

  • Publication number: 20100040816
    Abstract: The present invention provides silk fibre reinforced composite materials comprising a thermoplastic polymer matrix, which are relatively light, whilst having a high impact resistance. The silk fibre reinforced composite materials of the present invention allow for an optimal dissipation of the impact energy such that they have a penetration resistance higher than 20 J per mm of plate thickness, more preferably more than 30 J per mm, most preferably more than 40 J per mm. Due to the high impact resistance of the fibrous composite material according to the present invention, panels or shells comprising such composites are particularly useful for the manufacture of objects, which in the course of their life cycle are subject to shocks or at risk of penetration.

  • Publication number: 20100040857
    Abstract: A method and apparatus for making a reactive polymer pre-impregnated reinforcement material, comprising applying a substantially non-volatile composition of substantially solid particles of a reactive thermoset resin to a porous substrate at ambient temperature, initially by melting a first portion of the particles of the reactive thermoset resin. The first portion of the particles of the reactive thermoset resin flows into interstices of at least one layer of the porous substrate and a remaining portion of the particles of the substantially non-volatile composition remains solid.

  • Patent number: 7662467
    Abstract: A CNT composite (10) includes a matrix (14) and a number of CNTs (12) embedded in the matrix. The matrix has a surface (102) and an opposite surface (104). Head portions of the respective CNTs are consistently oriented, parallel to the surfaces of the matrix. A method for manufacturing the composite includes (a) providing a substrate and depositing a catalyst film on the substrate; (b) forming the array of CNTs via the catalyst film on the substrate; (c) immersing the CNTs in a liquid matrix material, infusing the liquid matrix material into the array of CNTs; (d) taking the carbon nanotubes with the infused matrix out of the liquid matrix; (e) pressing the still-soft matrix and the CNTs therein, in order to arrange the CNTs consistently and parallel to the surfaces of the matrix; and (f) solidifying and peeling away the matrix to produce the CNT composite.

  • Publication number: 20100009160
    Abstract: A method of producing carbon nanofibers includes grinding untreated carbon nanofibers produced by a vapor growth method. The untreated carbon nanofibers are ground so that the ground carbon nanofibers have a tap density 1.5 to 10 times higher than that of the untreated carbon nanofibers. A method of producing a carbon fiber composite material includes mixing carbon nanofibers into an elastomer, and uniformly dispersing the carbon nanofibers in the elastomer by applying a shear force to obtain a carbon fiber composite material.
