  • Patent number: 10953418
    Abstract: According to an embodiment, a method of applying loose-fill insulation within a cavity is provided. The method includes blowing loose-fill insulation particles into a cavity of a structure to install the loose-fill insulation within the cavity and thereby insulate the structure. The method also includes applying water (e.g., water mist) to the loose-fill insulation particles so that a moisture content of the installed loose-fill insulation is between about 2% and 20%. The water aids in retaining the loose-fill insulation particles within the cavity without requiring the use of an enclosure member that encloses the cavity and the loose-fill insulation is substantially free of a water soluble adhesive material that adheres the loose-fill insulation particles together within the cavity.

  • Patent number: 10954349
    Abstract: This invention relates to a process of making a fiber-reinforced composite. Glass fibers may be provided. These glass fibers may be treated with a sizing composition that has a coupling-activator compound with the formula: S—X-(A)n, where S represents a silicon-containing coupling moiety capable of bonding to the surface of glass fibers, X represents a linking moiety, and (A)n, represents one or more polymerization activator moieties. The treated glass fibers may be combined with a resin to make a fiber-resin mixture. The resin may have a monomer, a catalyst, and an activator compound capable of initiating a polymerization of the monomer. The monomer may be a lactam or lactone having 3-12 carbon atoms in the main ring. The fiber-resin mixture may then be cured so that the monomer polymerizes to form a thermoplastic polymer matrix of the fiber-reinforced composite. The thermoplastic polymer matrix may be formed by in situ polymerization initiated from both the surface of the glass fibers and the resin.
