Apparatus for forming blanks from fibrous material
An apparatus for forming blanks from fibrous material is disclosed. The apparatus includes a die having a porous body with a plurality of perforations extending there through, the plurality of perforations having varying sizes and being layered from a top surface to a bottom surface of the porous body. A smooth molding surface is provided on the top surface to hold the fibrous material and allow water to drain from the fibrous material through the plurality of perforations.
Apparatus and method for producing fiber composite preform
Disclosed is an apparatus for producing a fiber composite preform. The apparatus includes a lower mold and a molding unit for molding a preform by pressing a fiber composite placed on a surface of the lower mold while the molding unit is deformed in accordance with a shape of the surface of the lower mold.
Foam insulation with thermoformable film coating and process for manufacture
A thermal/acoustic insulation product, such as for an aircraft, comprising a block of flexible, open-celled, cellular foam having a predefined shape and having a thermoformed amorphous film covering that completely envelops the foam block. A process for making the insulation product includes first cutting the block of foam to a predefined shape, such as a shape suitable for placement in an area of an aircraft in need of insulation. Then, a first sheet of film is heated to its melt point and conformed to a first surface area of the block, and a second sheet of film is heated to its melt point and conformed to a second surface area of the block, wherein the first film and the second film are joined to one another at one or more seams. The insulation product may then be installed in an aircraft.
Thermoplastic polyurethane compositions, articles, and methods thereof
Disclosed herein are improved thermoplastic polyurethane compositions, articles, and related methods. These compositions include aliphatic thermoplastic polyurethanes having a hard segment content ranging from 57 percent to 80 percent by weight. The hard coat compositions have a Shore D hardness of at least 70 and can display an Elongation at Break test result at 25 degrees Celsius of at least 150 percent. These materials, when hardened, can serve decorative and/or protective functions while displaying both a high degree of elongation at moderate temperatures and high hardness.

METHOD AND DEVICE FOR FORMING LAYERED WORKPIECE
A method for forming a layered workpiece includes a transfer step of attaching a sheet material 44 to a second mold 30 to transfer a pattern to the sheet material 44. A first mold 20 is provided with a sucking hole 22 penetrating the first mold 20 to open at a portion that comes into contact with a workpiece body 42, a second sucking device 52 that sucks the workpiece body 42 is connected to the sucking hole 22, a hole is created, before or during sucking by the second sucking device 52, at a place on the sheet material 44 in a non-bonded region X to moderate sucking by the second sucking device 52 so that the sheet material 44 does not attach to the non-bonded region X of the workpiece body 42.
