A bulletproof panel includes: (i) a ceramic plate A; (ii) at least one phenol resin impregnated aramid fabric laminate C having phenol resin impregnated aramid fabrics C1, C2 and C3 which are laminated thereon; and (iii) an epoxy resin impregnated fabric B disposed between the ceramic plate A and the phenol resin impregnated aramid fabric laminate C, and impregnated with an epoxy resin. The phenol resin impregnated aramid fabrics C1, C2 and C3 may be aramid fabrics impregnated with a phenol resin, and aramid fabrics impregnated with a phenol/polyvinyl butyral mixture resin. The ceramic plate A and the phenol resin impregnated aramid fabric laminate C are not delaminated from each other even under a high-temperature environment, and thereby greatly enhancing the bulletproof performance.

A method is for manufacturing a honeycomb structure including a core material in which a hole is formed to penetrate in a thickness direction and is arranged in a plane direction, and a skin material that is stacked on a surface of the core material. The skin material includes a thermosetting resin. The method includes half-curing the thermosetting resin by placing the skin material in a bag and heating the skin material in a state where an inside of the bag is evacuated and an outside of the bag is under an atmospheric pressure; stacking the skin material in which the thermosetting resin is half-cured onto a side of the surface of the core material; and bonding and integrating the core material and the skin material with each other by pressurizing and heating the stacked core material and skin material with the use of a sealing pressurizing heating facility.

A light modulation device is disclosed herein. In some embodiments, a light modulation device includes a first polymer film substrate, a second polymer film substrate, an active liquid crystal layer disposed between the first and second polymer film substrates, wherein the active liquid crystal layer is capable of switching between a first orientation state and a second orientation state different from the first orientation state under an applied voltage, the first and second polymer film substrates have an in-plane retardation of 4,000 nm or more for light having a wavelength of 550 nm, a ratio of an elongation (E1) in a first direction to an elongation (E2) in a second direction perpendicular to the first direction of 3 or more, and wherein an angle formed by the first directions of the first and second polymer film substrates is in a range of 0 degrees to 10 degrees.

The present disclosure is concerned with chub packaging webs with improved puncture resistance suitable for use in chub packaging. The webs have a double waii partially laminated structure. The structure is conveniently formed by adhesively laminating two component films in a face to face configuration using a pattern of adhesive which leaves a substantial portion of the two facing surfaces unlaminated. Preferably, each of the component films comprise at least one layer of nylon and has a moisture content of greater than 1% by weight such that the double wall partially laminated web has a total energy impact absorption value of greater 0.59 foot-pound at −20° C. measured in accordance with ASTM D-7192 test method.

A cover panel, for at least partially transparently covering at least one display instrument in a vehicle, has a microstructure applied on at least one surface. The microstructure is suitable for scattering visible light which is incident on the cover panel. The at least one window region of the cover panel is cutout from the microstructure. A method for manufacturing such a cover panel uses a molding tool with an applied microstructure matrix for forming a microstructure on a part of the molding tool which is assigned to a surface of a molded cover panel. The parts of the molding tool which are assigned to window regions are cut out from the microstructure matrix.
