A method of thermoforming a rigid film construction. The method comprises: applying a rigid film construction to a mold; and heating the rigid film construction until it conforms to the mold. The rigid film construction includes a rigid polymeric film layer; a light-modifying film layer; and a shielding film layer. The shielding film comprises polymethyl methacrylate (PMMA); and the shielding film layer contacts the surface of the mold.

A method for manufacturing an exterior for a secondary battery includes a first step of preparing a sheet and a mold in which a recess part is formed; a second step of locating the sheet so that a portion of the sheet faces the recess part of the mold; and a third step of supplying a fluid from a side of the mold toward the recess part to form a forming part having a shape corresponding to a shape of the recess part in an area of the sheet, which is provided on the recess part. An exterior for a secondary battery and an apparatus for manufacturing the exterior for the secondary battery are also provided.

The first parison forming device comprises a first extruder, a first accumulator, and a first injection head, the first parison forming device is configured to form a first parison by injecting a first molten resin from the first injection head after the first molten resin extruded from the first extruder is accumulated in the first accumulator, the second parison forming device comprises a second extruder, a second accumulator, and a second injection head, the second parison forming device is configured to form a second parison by injecting a second molten resin from the second injection head after the second molten resin extruded from the second extruder is accumulated in the second accumulator.

A battery assembly includes at least one enclosure structure that is thermoformed about a battery assembly of a battery pack. A method of enclosing a battery assembly can include placing a sheet of material adjacent a battery assembly of a battery pack; and thermoforming the sheet of material about the battery assembly to provide an enclosure structure for the battery assembly.

Radome structures comprising a structural layer comprising a fiber reinforced thermoplastic composite including a fiber reinforcement and a thermoplastic resin. In addition, one or more RF matching layers may be disposed on at least one side of the structural layer. The RF matching layer comprising a first dielectric constant value that is lower than that a dielectric constant value of the structural layer. In this regard, the RF matching layer may provide smaller discrete changes in dielectric constant through a thickness of the radome to provide enhanced RF performance. In an example, a resin content of the thermoplastic resin of the fiber reinforced thermoplastic composite is not fewer than 25 weight percent and not more than about 60 weight percent, which provides enhanced RF performance relative to structural performance of the radome. In turn, manufacturing cost and complexity may be reduced by use of the thermoplastic materials as described herein.

A resin-integrated fiber sheet 1 for vacuum forming for producing a fiber reinforced resin molded body through vacuum forming includes: unidirectional continuous fibers 2 that are spread fibers of a continuous fiber group and arrayed in parallel in one direction; bridging fibers 3 lying in directions crossing the unidirectional continuous fibers 2; and thermoplastic resin 4 present on part of the surface of the unidirectional continuous fibers 2 to unify the unidirectional continuous fibers 2 and the bridging fibers 3. A fiber reinforced resin molded body of the present invention is a vacuum formed body in which two or more of the resin-integrated fiber sheets 1 are stacked. A method for producing the molded body of the present invention includes subjecting the resin-integrated fiber sheets 1 to vacuum forming from a lower mold with a vacuum line and pressurizing the sheets with compressed air from an upper mold. Thus, the present invention provides a resin-integrated fiber sheet for vacuum forming having excellent shapeability and avoiding voids, a molded body including the same, and a method for producing the molded body including the same.

A luggage room board includes the luggage room board main body made of resin and is configured to be opened and closed. At one of ends of a non-woven fabric, a concave portion is provided on a surface of the luggage room board main body to which the non-woven fabric is attached, and the end of the non-woven fabric is attached so as to enter the concave portion. The concave portion is formed such that a depth gradually increases toward the end of the non-woven fabric. The depth of the concave portion at the end of the non-woven fabric is approximately same as the thickness of the non-woven fabric or larger than the thickness of the non-woven fabric. The concave portion is provided at the end of the non-woven fabric on a side of the rotation center line.
