  • Patent number: 11578487
    Abstract: A wood or engineered wood structural panel, such as, but not limited to, OSB (“oriented strand board”) or plywood, that is both fire-resistant and water resistant. The panel is factory-coated with a product that provides fire resistance. The treatment gives it a Fire-Resistant (FR) performance (for use in a one- or two-hour rated assembly). The panel also is overlaid or coated in a factory setting with a weather/water resistive barrier (WRB). The structural panel thus combines a fire-resistant structural sheathing and WRB product in one integrated panel produced at a factory prior for installation at a job site.

  • Patent number: 11524470
    Abstract: A method for making a three-dimensional composite part with a thermoplastic matrix and continuous reinforcement. A pre-impregnated fibrous perform is obtained by three-dimensional knitting. The preform is placed on the punch or in the matrix of a tooling, defining between them a sealed closed cavity. The tooling is closed so as to apply a first pressure to the preform. The cavity is brought to the melting temperature of the polymer impregnating the preform by maintaining the first pressure. The cavity comprising the preform is cooled to a temperature suitable for demolding by maintaining the second pressure. The mold is opened and the part is demolded.
