A method for producing a composite material molded article, including laminating a fibrous filler on a mold; pressure-reducing inside an airproof space, the airproof space being formed with the mold laminated with the fibrous filler and an airproof film covering thereon; and impregnating a resin material in the fibrous filler, the formation of the airproof space including bonding the mold and the airproof film with a seal material containing a (meth)acrylic polymer as an adhesive. The composite resin molded article obtained by the method of the present invention can be suitably used in fields in which composite materials of fibrous fillers such as glass fibers and carbon fibers are generally used, for example, housings, structural members, and the like for moving objects or movable objects.

A method of curing a composite layup may include applying an inner bag vacuum pressure to an inner bag chamber and an outer vacuum pressure to an outer vacuum chamber. The vacuum inner bag chamber may be formed by a vacuum bag covering a composite layup and sealed to a forming tool with an inner bag chamber seal. The inner bag vacuum pressure may be no less than the outer vacuum pressure. The temperature of the composite layup may be increased to an elevated temperature to initiate a temperature hold period. The method may additionally include venting the outer vacuum chamber to atmosphere to initiate an outer vacuum chamber venting period during the temperature hold period, and applying compaction pressure to the inner bag chamber seal during the outer vacuum chamber venting period. The outer vacuum pressure may be re-applied to the outer vacuum chamber to terminate the outer vacuum chamber venting period.

Disclosed is a method implemented by computer for determining a lens blank intended to be used for the manufacturing of a finished optical article. The method includes: a virtual volume data determining step, during which virtual volume data are determined based at least on finished optical article data representative of the volume of the finished optical article and over-thickness data representative of over-thickness requirements, the virtual volume data are determined so that the virtual volume defined by the virtual volume data includes the volume of the finished optical article volume of the finished optical article and the over-thickness, a lens blank determining step, during which a lens blank is determined based on the virtual volume data so as to include the virtual volume defined by the virtual volume data.

An assembled mandrel for forming a hollow structure having a shape similar to that of the assembled mandrel, by layering a prepreg on the surface of the longitudinally oriented assembled mandrel, covering the same with a vacuum bag, heating while creating a vacuum inside the vacuum bag, and heat-curing the prepreg while pressing the same into the assembled mandrel, the assembled mandrel being characterized by being equipped with: two outer mandrel members (first mandrel members) extending in the longitudinal direction; a center mandrel member (second mandrel member) sandwiched between the two outer mandrel members, and capable of being withdrawn in the lengthwise direction from between the two outer mandrel members after the hollow structure has been formed; and a tape (detachable member) formed from a low-friction material and adhered to one or more of the contact surfaces between the two outer mandrel members and the center mandrel member.

A molding method and a molding system for improving a molding speed of a resin molded member. In the method, firstly a thermoplastic resin composite material is filled in a metal mold (i.e., at time T0), and subsequently a mold-clamping process gets started. As the mold-clamping process progresses, a first decompression circuit starts to decompress an inside of a cavity when the cavity is closed by a sealing member provided on the metal mold. Then, as the mold-clamping process further progresses, the thermoplastic resin composite material thus filled in the metal mold contacts an upper mold of the metal mold (i.e., at time T2). After that, a second decompression circuit starts to decompress the inside of the cavity, thereby to complete the mold-clamping process (i.e., at time T3).

An optical lens casting gasket, wafer, and system and method that provides for more efficient formation of optical lenses employing optically functional wafers.

A system and method for producing a comestible baked product in complex shapes using upright cast molding wherein a portion of the interior cavity forms a baking cup which can optionally receive a liner. Embodiments generally include a first part and second part that are configured to be joined together along a seam. When configured, an outer surface is created and an inner surface cavity which creates a contiguous internal hollow space in the form of a three-dimensional shape is formed. A portion of this internal hollow space forms a cup. The cup can be circular shaped or a different shape entirely such as a square. The mold may provide a means for supporting the mold in its designated position. Other embodiments may include a single piece that is attachable to the rim of a cup of a multi-cup baking pan or to a single stand-alone cup.

A mold for producing comestibles in complex shapes wherein at least a portion of the mold is edible. The mold can be constructed entirely of an edible material or may be an interior mold element constructed of an edible material that is placed within a non-edible mold support. The mold may define an opening for injecting a substance into an interior cavity. When the mold is placed into an oven, the substance may begin to melt and as such, the edible mold begins to melt or dissolve around the baking substance. In such circumstances the comestible product includes an interior and an exterior shell or veneer.

An in-mold sealing system for sealing openings in a wind turbine blade mold, the system including a wind turbine blade mold having an interior surface configured to form a surface of the wind turbine blade, the interior surface of the mold having at least one opening therein, at least one boss disposed within the at least one opening of the mold, the boss extending a distance beyond the interior surface of the mold, a flexible diaphragm having opposing first and second surfaces, with the first surface facing the mold, the flexible diaphragm disposed over the opening in the mold surface and a gasket, the gasket having a first surface coupled to a perimeter portion of the flexible diaphragm, and a second surface coupled to the interior surface of the mold, wherein the gasket circumscribes the opening.

An aircraft window assembly (10) includes a first panel (12) having a first surface (14) and a second surface (16). In a first state in which there is no pressure difference between the first surface (14) and the second surface (16), the first panel (12) has a cross-sectional shape selected from planar, outwardly convex, or inwardly convex. In a second state in which there is a pressure difference between first surface (14) and the second surface (16), the first panel (12) has an outwardly convex cross-sectional shape.
