An external light-shielding layer capable of enhancing a visible light transmittance and a contrast ratio and preventing Moire fringe and Newton ring phenomena, a display filter including the external light-shielding layer, and a display device including the display filter. The external light-shielding layer includes a transparent resin matrix, and a plurality of light-shielding patterns formed on the transparent resin matrix and spaced apart from each other in a predetermined interval, wherein a bias angle (α) formed between a traveling direction of the light-shielding patterns and the longer side of the matrix is in a range of about 5 to 80 degrees.

A double vacuum bag molding assembly with improved void management and laminate net shape control which provides a double vacuum environment for use in fabricating composites from prepregs containing air and / or volatiles such as reactive resin matrix composites or composites from solvent containing prepregs with non-reactive resins matrices. By using two vacuum environments during the curing process, a vacuum can be drawn during a B-stage of a two-step cycle without placing the composite under significant relative pressure. During the final cure stage, a significant pressure can be applied by releasing the vacuum in one of the two environments. Inner and outer bags are useful for creating the two vacuum environments with a perforated tool intermediate the two. The composite is placed intermediate a tool plate and a caul plate in the first environment with the inner bag and tool plate defining the first environment. The second environment is characterized by the outer bag which is placed over the inner bag and the tool plate.

A solid surface material with an antimicrobial agent in a thermoset and / or thermoplastic resin matrix where the antimicrobial agent comprises a chitosan-metal complex.

This invention relates to an aluminum conductor composite core reinforced cable and method of manufacture. The composite core comprises a plurality of longitudinally extending fibers embedded in a resin matrix. The composite core comprises the following characteristics: tensile strength ranging from about 250 to about 350 Ksi; a tensile modulus of elasticity ranging from about 12 to about 16 Msi; and a coefficient of thermal expansion less than or equal to about 6×10−6 cm / cm·° C. The composite core is further manufactured according to a one or more die pultrusion system, the system comprising tooling designed in accordance with the processing speed, selection of composite core fibers and resin and desired physical characteristics of the end composite core.

A fiber optic drop cable including at least one optical waveguide, at least one roving, and a cable jacket. In one embodiment, the at least one roving includes a resin matrix having a water-based acrylic composition that includes an ethylene-acrylic acid and a water-swellable component. The resin matrix has a percent by weight of about 10 percent or less of the flexible roving so that the at least of one roving is at least partially bonded with the cable jacket, thereby inhibiting buckling of the cable jacket. In another embodiment, a plurality of rovings are arranged in clusters in the cable for influencing the bonding between the rovings and cable jacket. Also, disclosed is a protective casing for protecting and routing optical fibers along with preconnectorized cable assemblies.

An exemplary light emitting diode (30) includes a light output unit (31), an optical lens (33) and a reflective film (35). The optical lens includes a light input surface (331) facing the light output unit, a top interface (333) opposite to the light input surface, and a light output surface (335) between the light input surface and the top interface. The reflective film is integrally formed on and in immediate contact with the top interface of the optical lens. The reflective film is made of a transparent resin matrix material dispersed with a plurality of reflective particles. A method for making the light emitting diode is also provided.

A partially or fully cured thermosetting product which includes a cured and molded product of a thermosetting composition. The composition includes 70% to 99% by weight of at least one thermosetting resin or compound and 1% to 30% by weight of at least one toughening agent. The toughening agent is at least one hyperbranched dendritic macromolecule formed of ester units, optionally in combination with ether units.

The invention relates to a method of fabricating an electricity transport conductor, in particular for overhead power lines, that are to operate at an operating temperature greater than or equal to 200° C., and comprising at least one composite central core 1 made of continuous fibers impregnated with an epoxy resin matrix, the core being covered in at least one layer of insulating material 2, and conductor wires 3 of aluminum or aluminum alloy being wound around the core. According to the invention, said insulating material is compatible with said operating temperature and is put into place on said core 1 without subsequent heating.

The apparatus of the present invention is generally characterized by a heating / inflation module having pressurizable interior and an attached heat curable pre-preg. In particular, an elastomeric, seamless composite is provided that includes a heating element disposed within a thermoset resin matrix. The composite adapted to maintain a consistent temperature profile and an internal air pressure. A first end piece is attached to a first end of the composite and has an air port for communication with a compressed air source, a vacuum port for communication with a vacuum supply source and at least one electrical cable port for communication with a power supply source. A second end piece attached to a second end of the composite. The apparatus further includes a pre-preg removably attached to an outer surface of the composite. The pre-preg includes a structural fiber matrix supporting a heat curable resin. The composite is constructed by applying a liquid silicone matrix to at least one layer of braided or wound and / or tape fibers, wherein a portion of the fibers are electrically conductive. The layer of braided fibers is introduced into a mold, and a removable, expandable inner bladder is then loaded into the mold. The inner bladder is inflated to conform the layer of braided fibers to an interior surface of the mold. An electric current is caused to flow to the conductive fibers to cure the silicone matrix into a stable, elastomeric state. The composite is removed from the mold. A method for repairing a damaged section of a conduit is also disclosed.
