摘要： The disclosure is to improve quality of a processed molded product. A processing apparatus is a processing apparatus for a composite material in which fibers and a thermoplastic resin are compounded. The processing apparatus includes a heating device configured to heat the composite material to a temperature higher than or equal to the melting point of the resin contained in the composite material; a mold configured to press the composite material; and a temperature adjustment unit configured to adjust the temperature of the mold. While the mold presses the composite material, the temperature adjustment unit maintains the temperature of the mold at a predetermined temperature at which a time required for solidification of the resin contained in the composite material matches a desired time.

摘要： A molding device is includes a mandrel that has an arc-shaped cross section; a roller that has a round-shaped cross section, is movable along a surface of the mandrel, and applies a pressing force to a material to be molded placed on the mandrel; a gripping unit that grips the material to be molded on an outside of the roller with respect to the mandrel and applies a tensile force to the material to be molded; a roller driving unit that moves the roller along the surface of the mandrel; a gripping-unit driving unit that moves the gripping unit. A control unit synchronizes a position of the roller and a position of the gripping unit with each other to control the roller driving unit and the gripping-unit driving unit so that the material to be molded is arranged in a direction perpendicular to a vertical direction of the mandrel.

摘要： A layered body includes a first layer with a plurality of first composite sheets, and a second layer with a plurality of second composite sheets in a state of contacting the first layer. The first composite sheets are disposed along an arrangement direction shaped as a curved line so that an end in a first longitudinal direction of one first composite sheet and an end in the first longitudinal direction of an adjacent first composite sheet are close to each other without overlapping in the thickness direction, and so that the first longitudinal directions of the sheets intersect each other. The second composite sheets are disposed along the arrangement direction so that an end in a second longitudinal direction of one second composite sheet and an end in the second longitudinal direction of an adjacent second composite sheet are close to each other without overlapping in the thickness direction.

摘要： A shaping method for shaping a stack produced by layering and forming into a flat shape a plurality of sheet-shaped composite materials includes a first shaping step of shaping the stack along a fold line extending along the longitudinal direction of the stack such that a first region and a second region, which are disposed to sandwich the fold line, form a first bending angle, and a second shaping step of shaping along the fold line the stack shaped via the first shaping step such that the first region and the second region form a second bending angle that is smaller than the first bending angle. In the first shaping step and the second shaping step, the stack is shaped in a state wherein the first region is maintained below the softening temperature of the resin material, while the second region is being heated to the softening temperature or higher.
