    摘要： Robotic tools, methods, and systems for repairing pipes in-situ are described. A robotic tool includes a body with an annular, cylindrical configuration with a first end and a second end opposite the first end, the body having an inner surface defining an axis; a printing arm attached to the inner surface of the robotic body using a track, the printing arm circumferentially movable along the inner surface of the body; a printing head attached to the printing arm, the printing head movable radially along the printing arm and axially relative to the printing arm; and a plurality of legs positioned at axial intervals around the robotic body, each leg pivotably attached to the robotic body at either the first end or the second end of the body and pivotable between an open position and a closed position.

    摘要： A filament winding assembly includes a rotating mandrel coupled to a shaft that rotates the rotating mandrel. The rotating mandrel includes a first perforated sleeve that defines holes and includes a winding surface. The rotating mandrel also includes a second perforated sleeve disposed inside the first perforated sleeve. The second perforated sleeve defines an interior volume and holes configured to form fluid pathways with the holes of the first perforated sleeve. The fluid pathways extend from the interior volume to the winding surface of the first perforated sleeve. The filament winding assembly includes a filament that is wound, under tension, around the winding surface of the first perforated sleeve. The filament winding assembly also includes a fluid source fluidically coupled to the interior volume of the second perforated sleeve. The fluid source exhausts fluid, through the fluid pathways, from the wound filament to reduce manufacturing defects of the wound filament.

    摘要： A method of manufacturing thermoplastic components includes receiving, by a movable die with an internal grooved surface that has a plurality of longitudinal grooves, spread dry fiber tows. The method also includes receiving, by the movable die and from a polymer extruder, molten polymer. The method also includes wetting, by the movable die, the spread fiber tows with the molten polymer. The method also includes moving, by the movable die, the wet fiber tows along the plurality of longitudinal grooves in a direction parallel to a length of the longitudinal grooves. The method also includes depositing, by the movable die, a layer of the wet fiber tows on a printing surface. The movable die moves along the printing surface to form a thermoplastic component of one or more layers of fiber tows on the printing surface.

    摘要： A photovoltaic module includes a plurality of ribbons; and a composite panel comprising a core layer and a skin layer supported by a surface of the core layer, where the core layer includes a core material and the skin layer is formed of a matrix material and a plurality of parallel fibers aligned with the ribbons and disposed in the matrix material. A method of making a photovoltaic module includes applying a pair of skin layers to a core layer, each skin layer including a skin material and a plurality of parallel fibers disposed in the skin material to make a composite sandwich panel; and layering a component including ribbons between the composite sandwich panel and a thin, transparent front sheet; wherein the parallel fibers are aligned with the ribbons; where the composite sandwich panel has a coefficient of thermal expansion matching the coefficient of thermal expansion of the component.

The method also includes receiving, by the movable die and from a polymer extruder fluidically coupled to the movable die, molten polymer. The method also include wetting, by the movable die, the spread fiber tows with the molten polymer. The method also includes maintaining, by the movable die, the wet fiber tows spread as the wet fiber tows exit the die. The method also includes depositing, by the movable die, a layer of the wet fiber tows on a printing surface. The movable die is configured to move along the printing surface to form a thermoplastic component of one or more layers of fiber tows on the printing surface.
