Method of producing resin frame member for fuel cell and processing die
In a method of producing a resin frame member for a fuel cell, a processing die is used. The method includes a processing step of moving an upper die toward a lower die to thereby form an inclined surface on each of side parts of a resin film. In the processing step, shearing is performed while maintaining a predetermined clearance between the lower processing section and the upper processing section and in a state where each of the side parts is at least partially positioned at a cutout so that each of the side parts is inclined downward toward the inside. The cutout is formed by cutting off an edge part of a placement surface that is positioned on the lower processing section side.
DIELECTRIC COMPOSITE WITH REINFORCED ELASTOMER AND INTEGRATED ELECTRODE
The present disclosure is directed to dielectric elastomeric composites that include a retainable processing membrane, an elastomer material, and an electrically conductive material. The elastomer layer may be partially imbibed into the retainable processing membrane. The retainable processing membrane may be porous. The retainable processing membrane is compacted in the transverse direction, machine direction, or in both directions prior to the application of an elastomer material and an electrically conductive material. The compaction of the retainable processing membrane may form structured folds or folded fibrils in the membrane, giving the retainable processing membrane a low modulus and flexibility. In some embodiments, the dielectric composites are positioned in a stacked configuration. Alternatively, the dielectric elastomeric composites may have a wound configuration. The dielectric composites have a total thickness less than about 170 .Math.m. The dielectric elastomeric composites may be used, for example, in dielectric elastomer actuators, sensors, and in energy harvesting.

Also disclosed is a method of improving barrier resistance of a polymer to a permeant, the method comprising forming a graphene-reinforced polymer matrix composite within the polymer. The packaging material may be used for packaging food, drug, perfume, etc. and to make various containers.
Barrier film for electronic devices
A barrier film for electronic devices exhibiting and maintaining excellent water barrier property. The barrier film for electronic devices features a water permeability (23° C., RH50%) that is set to be not more than 10.sup.−4 g/m.sup.2/day and a water content that is maintained to be not more than 2000 ppm.
Peel-off detection label
The invention relates to a peel detection label that is a laminate including a support, a pattern layer formed in a part of the surface of the support, and a pressure-sensitive adhesive laminate having at least a low modulus layer (X), a high modulus layer (Y) and a pressure-sensitive adhesive layer (Z) in that order, in which the low modulus layer (X) has an n-layered structure (where n is an integer of 1 to 10) having a surface in contact with the support and the pattern layer and a surface in contact with the high modulus layer (Y), and the low modulus layer (X) satisfies a specific thickness-average shear storage elastic modulus.
Tunable energy absorber
An energy absorber for interposition between a cover and a covered object includes a generally planar matrix of cells. Each of the cells includes a plurality of generally elongate micro-elements interconnected to form a cell micro-structure, with each cell having a respective energy absorption capacity such that an energy absorption capacity of the energy absorber varies across at least one direction. The cells are configured such that impulse of an object with the cover with the energy absorber sandwiched between the cover and the covered object causes a deceleration vs. time response in the object, beginning with a generally linear rise in the deceleration to a peak deceleration within 5 ms after the beginning of the impulse event, followed by a generally nonlinear decrease in the deceleration over a period of not greater than 15 ms to a final target deceleration of not greater than 10% of the peak deceleration.
Transfer system for electronic-technology textile printing
System with at least two layers as a mean or system for transferring electrically conductive ink adapted to receive and transfer said ink on a textile substrate by a thermal transfer.
Structural Member Consisting of Dissimilar Polymer Materials
A structural member including a lightweight core, one or more skins, and a crosslinking nanolayer interposed therebetween that results in significant mechanical strength in the structure. The core is a polymer of reduced density by way of included voids, such as an open or closed cell foam, honeycomb, or corrugated structure. The core polymer has a lower density and may have a higher softening or melting temperature than the polymer skin materials. The core may be discontinuous at the interface with the skin such that only a small percentage of the core surface is actually in contact with the skin compared to the overall area of the interface. The skin may be a thermoplastic layer that attaches to the core material. The skin may be a composite material including non-thermoplastic reinforcements. The crosslinking nanolayer is covalently bonded to the surface of the core material and provides molecular compatibility with the skin material.
BONDED BODY OF METAL AND RESIN, AND METHOD FOR BONDING METAL AND RESIN
