  • Patent number: 9840061
    Abstract: Structural panels and methods of making composite material for such structural panels may include applying a resin to a nonwoven fibrous web, where the nonwoven fibrous web includes a combination of glass fibers and polymer fibers. The web may be dried at a first stage temperature at or below a curing temperature of the resin for a time sufficient to substantially dry but not substantially cure the resin. The web may be laminated at a second stage temperature sufficient to fully cure the resin to produce a composite material. The second stage temperature may be above the melting point of the polymer fibers, and the resin may cause the composite material to retain a substantially rigid shape upon completion of the laminating operation.

  • Patent number: 9770876
    Abstract: In a method of manufacturing an object, a filament is fed to an extrusion head. The filament has a semi-crystalline polymeric reinforcement portion and a polymeric matrix portion. The temperature of the filament is raised in the extrusion head above the melting point of the matrix portion but below the melting point of the reinforcement portion so that the matrix portion of the filament melts within the extrusion head, thereby forming a partially molten filament within the extrusion head. The reinforcement portion of the partially molten filament remains in a semi-crystalline state as it is extruded from the extrusion head. Relative movement is generated between the extrusion head and the substrate as the partially molten filament is extruded onto the substrate in order to form an extruded line on the substrate. The matrix portion of the extruded line solidifies after the extruded line has been formed on the substrate.

  • Patent number: 9758925
    Abstract: To prepare a shaped product comprising a thermal adhesive fiber under moisture and having a fiber aggregate nonwoven structure. In the shaped product, the thermal adhesive fibers under moisture are melted to bond to fibers constituting the fiber aggregate nonwoven structure and the bonded fiber ratio is not more than 85%. The shaped product has an apparent density of 0.05 to 0.7 g/cm3, a maximum bending stress of not less than 0.05 MPa in at least one direction, and a bending stress of not less than ? of the maximum bending stress at 1.5 times as large as the bending deflection at the maximum bending stress. The moistenable-thermal adhesive fiber may be a sheath-core form conjugated fiber comprising a sheath part comprising an ethylene-vinyl alcohol-series copolymer and a core part comprising a polyester-series resin. Such a shaped product can be used for a building board or the like since the shaped product has a high bending stress although the product is light and has a low density.
