  • Patent number: 11951712
    Abstract: A glass facer for a constructions board includes a first non-woven layer of coarse fibers and a second non-woven layer of coarse fibers and microfibers. The glass facer also includes a binder that simultaneously binds or adheres the coarse fibers of the first non-woven layer together, the coarse fibers and the microfibers of the second non-woven layer together, and the first non-woven layer to the second non-woven layer. The first non-woven layer has a porosity and air permeability that enables the first non-woven layer to absorb a material of the construction board when the glass facer is positioned atop the construction board during manufacture of the construction board. The second non-woven layer is configured to block the material of the construction board from passing through the glass facer to an exterior surface of the second non-woven layer so that the material is not externally visible.

  • Patent number: 11919213
    Abstract: A method for producing injection-molded parts by a two-component injection-molding technique in which a first material component is injected into a mold cavity and is displaced into peripheral regions of the mold cavity by injecting a second material component. The first material component is injected into a partial region of the mold cavity at a first gating point and the second material component is injected into the mold cavity at a second gating point and, as a result, the first material component is acted upon by the second material component and displaced in the direction of the regions of the mold to be filled with the first material component. The first material component is thereby displaced into regions of the mold at the wall, and the second material component is introduced in those regions of the mold as a core material and completely into other regions of the mold.

  • Patent number: 9272495
    Abstract: A method and apparatus for compacting composite stringers. In one illustrative embodiment, an apparatus comprises a compacting structure, a compactor vacuum system, and a carrier vacuum system. The compacting structure has a shape configured to contact layers of uncured composite material for a composite stringer. The compactor vacuum system is associated with the compacting structure. The compactor vacuum system is configured to cause the compacting structure to apply a pressure to the layers of uncured composite material when a compactor vacuum is applied to the compactor vacuum system. The carrier vacuum system is associated with the compacting structure. The carrier vacuum system is configured to hold the layers of uncured composite material against the compacting structure when a carrier vacuum is applied to the carrier vacuum system.

  • Patent number: 9238337
    Abstract: A molding die is mainly constituted of a die surface shell layer (15) having a die surface (32) responsive to the shape of a composite item and a support (16) supporting the die surface shell layer (15). The die surface shell layer (15) is made of a material having air permeability, and a prepreg material (34) is placed on a die-shaped surface (32) thereof. Then, the prepreg material (34) is covered with a nonpermeable vacuum bag film (35), and a cavity portion (30) of the support (16) is evacuated. The die surface shell layer (15) has air permeability, whereby it follows that air present on the die-shaped surface (32) is also discharged into the cavity portion (30) through the die surface shell layer (15). Consequently, the prepreg material (34) is pressed against the die-shaped surface (32) by the atmospheric pressure outside the vacuum bag film (35), and strongly adheres.

  • Patent number: 9221223
    Abstract: A method of forming a container includes providing a preform of the container. The preform has a wall with an interior region and an exterior region. The method also includes disposing the preform in a mold cavity wherein the mold cavity has a mold surface. Furthermore, the method includes introducing a substance into the preform to expand the preform toward the mold surface. The interior region of the wall has a first interior temperature prior to the introduction of the substance and a second interior temperature after the introduction of the substance. The exterior region of the wall has a first exterior temperature prior to the introduction of the substance and a second exterior temperature after the introduction of the substance. The method further includes controlling the first interior temperature to be greater than the first exterior temperature prior to the introduction of the substance.
