A method for producing a film for a composite pane of a motor vehicle, which film serves as an intermediate layer of the composite pane, comprising the following steps: providing a polyvinyl butyral (PVB) film base material or an ethylene vinyl acetate copolymer (EVA) film base material; providing at least one colorant; mixing the PVB or EVA film base material with the at least one colorant; liquefying the mixture of the PVB or EVA film base material and the at least one colorant; extruding the film from the liquefied mixture of the PVB or EVA film base material and the at least one colorant; treating the extruded film section by section by irradiating the film in order to form sections of different light transmissivity.

Radiation-shielding composite materials and their methods of manufacture. Such methods may include adding a metal hydride to a hardenable matrix precursor, adding a reinforcing material to the hardenable matrix precursor, and hardening the matrix precursor to form a composite material that incorporates the reinforcing material and the metal hydride in a solid matrix. The resulting radiation-shielding composite materials are configured to attenuate incident radiation, and may be used in the construction of panels, laminate structures, buildings, and aerospace vehicles, among others.

A composite composition includes a thermoset resin and about 3 wt. % to about 35 wt. % of at least one material selected from the group consisting of cellulose nanofibrils (CNF), micro-sized cellulose fibers (MFC), and cellulose nanocrystals (CNC) dispersed therein as measured with respect to the overall weight of the composite composition. The cellulose nanofibrils and/or nanocrystals have an average diameter of about 5 nm to about 500 nm and an average aspect ratio in the range of about 5:1 to about 500:1. The cellulose micro-sized fibers have an average diameter of about 5 μm to about 100 μm and an average aspect ratio in the range of about 5:1 to about 250:1.

A composite core material and methods for making same are disclosed herein. The composite core material comprises mineral filler discontinuous portions disposed in a continuous encapsulating resin. Further, the method for forming a composite core material comprises the steps of forming a mixture comprising mineral filler, an encapsulating prepolymer, and a polymerization catalyst; disposing the mixture onto a moving belt; and polymerizing said encapsulating prepolymer to form a composite core material comprising mineral filler discontinuous portions disposed in a continuous encapsulating resin.

A film for laminated glass, the film including a surface embossing pattern formed on at least a portion of one side of the film, wherein the surface embossing pattern comprises convexities, and concavities separating the convexities from one another, each of the convexities is surrounded by some of the concavities, and an average area of the convexities is 0.01 mm.sup.2 to 4.00 mm.sup.2.

A battery separator comprises a co-extruded, microporous membrane having at least two layers made of extrudable polymers and having: a uniform thickness defined by a standard deviation of <0.80 microns (m); or an interply adhesion as defined by a peel strength >60 grams.
