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： According to one implementation, a prepreg lamination apparatus includes first and second rollers, a table, and a feed structure. The first roller sends out a first prepreg tape which is a part of material of an FRP. The second roller sends out a second prepreg tape which is another part of the material of the FRP. The table is for laminating the first and second prepreg tapes directly or indirectly. The feed structure is adapted to feed out the first and second prepreg tapes in a feeding direction by moving the first and second rollers relatively to the table while performing at least one of movement of the first roller relatively to the second roller, and rotation of at least one of the first and second rollers relatively to the table around an axis which is not parallel to each of rotation axes of the first and second rollers.

摘要： A method and apparatus for the additive manufacturing of three-dimensional objects are disclosed. Two or more materials are extruded simultaneously as a composite, with at least one material in liquid form and at least one material in a solid continuous strand completely encased within the liquid material. A means of curing the liquid material after extrusion hardens the composite. A part is constructed using a series of extruded composite paths. The strand material within the composite contains specific chemical, mechanical, or electrical characteristics that instill the object with enhanced capabilities not possible with only one material.
