Method for manufacturing composite material product
Provided is a technology for imparting a design having a higher degree of freedom than in the related art to a composite material product including a woven fabric, which is formed of a thread made of a specific fiber (carbon fiber, glass fiber, aramid fiber), and a resin. As a first step, a specific fiber cloth (100), which is the woven fabric formed of the thread made of a specific fiber, and a backing sheet (200) formed of a thermoplastic resin are stacked. Subsequently, embroidery is performed with an embroidery thread (300) to form a design on a front surface of the specific fiber cloth (100). The embroidery thread (300) is made of the specific fiber, and penetrates through the specific fiber cloth (100) and the backing sheet (200). Then, the specific fiber cloth (100) and the backing sheet (200) are sandwiched between resin sheets (400) each formed of a thermoplastic resin, and the whole is cured by an RFI method.
Glass reinforced polymer composite and method of manufacture
A method and process is provided for manufacturing a glassed reinforced polymer composite laminate panel. The method and process includes the steps of providing a mold including a flexible polymer film; depositing a layer of gel coat on the flexible polymer film; curing the layer of gel coat to provide a semi-rigid intermediate panel; applying a layer of resin material overtop of the cured gel coat layer; laying a sheet of woven or non-woven surface veil material over top of the cured gel coat layer; laying a sheet of glass reinforced matte overtop of the surface film sheet; applying a second layer of resin material overtop the sheet of glass reinforced matte to form the glassed reinforced polymer composite laminate panel; and curing the glassed reinforced polymer composite laminate panel. The method for manufacturing the composite laminate panel can be a continuous process making a panel of indeterminate length.
Automated manufacturing method and system and in-mold coated plastic article produced thereby
An automated manufacturing method and system and in-mold coated plastic article produced thereby are provided. The system includes a combination compression and injection mold and a plurality of program-controlled manipulators. An automatic sprayer supported on a first manipulator sprays at least a portion of a mold surface with an in-mold coating composition. An end effector supported on a second manipulator picks up a heated blank of moldable plastic sheet material from an oven and places the heated blank in the mold. An inner portion of the heated blank is forced into an article-defining cavity of the mold and into contact with at least a portion of the composition. The composition and the inner portion cure and bond to one another and a plastic compatible with the plastic of the sheet is injected into the mold so as to form the coated plastic article.
Method for manufacturing multilayer printed wiring board
A first stack is formed by stacking a first sheet of metal foil, a first prepreg, and a second sheet of metal foil, one on top of another. The first prepreg is thermally cured by thermally pressing these members to make a double-sided metal-clad laminate. Conductor wiring is formed by partially removing the first sheet of metal foil from the double-sided metal-clad laminate to make a printed wiring board. After a third sheet of metal foil has been preheated, the conductor wiring of the printed wiring board, a second prepreg, and the third sheet of metal foil are stacked one on top of another and thermally pressed together. The first insulating layer has a lower linear expansion coefficient than any of the first sheet of metal foil or the second sheet of metal foil does.
Automated Manufacturing Method and System and In-Mold Coated Plastic Article Produced Thereby
An automated manufacturing method and system and in-mold coated plastic article produced thereby are provided. The system includes a combination compression and injection mold and a plurality of program-controlled manipulators. An automatic sprayer supported on a first manipulator sprays at least a portion of a mold surface with an in-mold coating composition. An end effector supported on a second manipulator picks up a heated blank of moldable plastic sheet material from an oven and places the heated blank in the mold. An inner portion of the heated blank is forced into an article-defining cavity of the mold and into contact with at least a portion of the composition. The composition and the inner portion cure and bond to one another and a plastic compatible with the plastic of the sheet is injected into the mold so as to form the coated plastic article.

Mold-releasable surfacing materials for composite parts
A surfacing material that is mold-releasable and electrically conductive. This surfacing material can be co-cured with a curable composite substrate and can be in contact with a mold surface such that when the cured composite part is removed from the mold, the surfacing material is releasable from the mold with ease. The mold-releasable surfacing material can effectively eliminate the need for mold release agents and mold surface preparation.

Forming metal composites
Examples of forming metal composites are described herein. In an example, a metal sheet is formed into a predetermined shape using superplastic thermal forming technique. Further, a carbon fiber-reinforced polymer sheet is shaped into the predetermined shape by thermal forming. The metal sheet and the carbon fiber-reinforced polymer sheet are coupled by applying an adhesive between the metal sheet and the carbon fiber-reinforced polymer sheet, to form a metal composite.
