Method for manufacturing glass resin laminated body
A method of manufacturing a glass resin laminated body includes a step of sticking a glass film on a resin film via an adhesive layer while holding the glass film and the resin film between a first roller that presses against the resin film and a second roller that is disposed opposite to the first roller and that presses against the glass film. A ratio of an elastic modulus P1 of a surface layer of the first roller to an elastic modulus P2 of the resin film P1/P2 satisfies a relation of 3?10.sup.?3?P1/P2?1.0.
Ballistic resistant sheets, articles comprising such sheets and methods of making the same
Ballistic resistant sheets (12), articles (10) comprising such sheets and methods of making the same are provided. The embodiments are especially adapted to facilitate the manufacture of curved ballistic resistant articles (e.g. curved ballistic resistant armor, helmets and the like). In preferred forms, the ballistic resistant sheets are a multi-monolayer construction including a core layer (12-1) formed of at least one first monolayer having first unidirectionally oriented reinforcing fibers and an elastomeric matrix material which is sandwiched between respective face layers (12-2) each formed of at least one second monolayer having second unidirectionally oriented reinforcing fibers and a non-elastomeric matrix material.
Backplate, support frame for backlight unit, backlight unit and display device
The present invention relates to the display technology field, and provides a backplate, a plastic-iron integrated structure, a backlight unit, and a display device. The backplate is provided with a first through hole, and the first through hole has an inner wall and an outer wall which form a projection structure on the backplate. When the backplate is bonded with a plastic frame to form the plastic-iron integrated structure, the plastic frame not only contacts the inner wall of the first through hole, but also contacts the surface of the projection structure, thus increasing the contact area between the plastic frame and the backplate, and increasing the bonding force between the plastic frame and the backplate. Even when the plastic frame shrinks in case of fluctuations in temperature and/or humidity, the plastic frame is not easily separated from the backplate, and the stability of the formed plastic-iron integrated structure is improved.
Unit cell injection mold for fuel cell
A unit cell injection mold for fabricating a unit cell of a fuel cell, in which an integrated frame of the unit cell formed by injecting a polymer resin onto an insert, in which a membrane electrode assembly and a gas diffusion layer are integrated, is formed, the unit cell injection mold includes an upper mold, a lower mold engaged with the upper mold to define an inner space between the lower mold and the upper mold, the inner space including an injection area into which the insert is accommodated and an insert area into which the polymer resin is injected to form the frame, and elastic protrusions formed from an elastic material, the elastic protrusions being disposed on the upper mold and the lower mold to face each other, wherein the elastic protrusions clamp the insert to divide the inner space into the insert area and the injection area to prevent the polymer resin from entering the insert area.
Constrained forming of contoured composite hat stringers
Cap wrinkling in a contoured composite hat stringer is reduced by constraining the cap as the hat stringer is being formed from a flat composite charge. The cap is constrained by an inflatable bladder placed in a tool set used to form the composite charge.
MOLDING METHOD AND DIE
Disclosed herein are a molding method and a mold capable of further reducing the distance between a base material and a seal member. A molding method includes: a preforming step of injecting a rubber material into a groove at a temperature where the rubber material is not vulcanized, in a cavity plate including the groove into which the rubber material is injected; and a vulcanization molding step of sandwiching a base material between the cavity plate and a mold, and molding the rubber material onto the base material as a seal member at a temperature where the rubber material is vulcanized. The cavity plate includes a gap forming portion between such portion and an inclined portion of the base material when a flat surface and a flat surface of the base material are pressed in the vulcanization molding, and a connecting groove connecting the groove and the gap forming portion.
THREE-DIMENSIONAL PRINTING NOZZLE STRUCTURE
A three-dimensional printing nozzle structure including a heater, a nozzle, a feed tube and a baffle member is provided. The heater has a first through hole. The nozzle is connected to the heater and has a second through hole. The feed tube passes through the first through hole and has a feed channel. The first through hole, the second through hole and the feed channel are aligned with each other. A filament moves along the feed channel to pass through the heater. The heater heats and melts the filament, and the filament that has been melted moves from the feed channel into the second through hole to be extruded. The baffle member is disposed inside the first through hole and located between the feed channel and the second through hole. The baffle member is configured to adjust a degree of communication between the feed channel and the second through hole.
Non-vented bladder system for curing composite parts
A composite part charge having an internal cavity is placed on a tool and covered by a vacuum bag for autoclave curing. A bladder is placed in the cavity to react autoclave pressure on the charge. The bladder is coupled with a flexible fluid reservoir located beneath the vacuum bag. The bladder is pressurized by autoclave pressure applied through the vacuum bag to the flexible fluid reservoir.
GRATING STRUCTURE, PREPARATION METHOD THEREOF AND DISPLAY DEVICE
Provided in the present disclosure are a grating structure, a preparation method thereof and a display device. The preparation method of the grating structure includes: forming a plurality of first convex structures arranged in a first direction; and forming a first rubber material at least covering the plurality of first convex structures, and forming the grating structure including a plurality of second convex structures by using convex structures including the first convex structures and the first rubber material, wherein a surface of the first rubber material facing away from the first convex structures is a flat surface, and the convex structures including the first convex structures and the first rubber material are in one-to-one correspondence with the second convex structures, shapes of cross sections of the second convex structures in the first direction are triangles, and the second convex structures have at least one inclined flat surface.
METAL-CLAD LAMINATE SHEET MANUFACTURING METHOD, AND METAL-CLAD LAMINATE SHEET USING THE SAME
