Unexpectedly unique and environmentally friendly composite material structures, storage articles fabricated therefrom, and related methods. The composite structure includes at least one or more fiber-containing layers, such as fiberboard or other layers having fibers from natural and/or synthetic sources, and one or more mineral-containing layers. The mineral-containing layer(s) comprises a thermoplastic bonding agent fixing the mineral particles in place. The fiber-containing layer(s) and mineral-containing layer(s) can be shaped, sized, and manufactured such that the composite structure formed therefrom is capable of being machined to form the storage article. The composite structure can be repulped and recycled without the use of dispersions, emulsions, or aqueous solutions. Further, the composite reduces layer mass requirements for heat seal, barrier, and fiber adhesion compared to polymer layers. The composite structure further has tensile strength and other structural characteristics that allow it to be readily machined into desired storage article forms.

Disclosed herein is a resin film. The resin film has a height difference of about 10 nm to about 65 nm between a convex portion and a concave portion on an outermost surface thereof, and has a difference in contact angle (ΔCA) of less than about 10°, as represented by Equation 1: ΔCA=|CA2−CA1| [Equation 1] Where in Equation 1, CA1 is a water droplet contact angle after a surface of a substrate coated with the resin film has been subjected to a 500-cycle reciprocating abrasion test using an eraser under a load of 500 g/cm2, and CA2 is a water droplet contact angle before the reciprocating abrasion test.Embodiments of the invention provide a novel and improved resin film capable of improving antifouling and slip properties and enhancing film strength, and a method of manufacturing the same.

A transaction card has a substructure consisting at least in part of a layer of fibrous material, such as carbon fiber strands or filaments, arranged in a pre-selected pattern, such as a weave pattern, that is at least partially enclosed by a transparent plastic film. A sheet is laminated on each of two opposing faces of the substructure to form a transaction card core. One or both of the sheets laminated on the opposing faces of the substructure is also made of a transparent material, and one or both of the two opposing faces of the transaction card core can be printed. An over-laminate film, such as a transparent polyvinyl chloride plastic film, can be laminated on each of two opposing faces of the transaction card core.

In one embodiment, a morphable composite three-dimensional structure is disclosed. The morphable composite three-dimensional structure comprises a flexible fiber-reinforced ceramic composite comprising a fiber preform and a ceramic matrix material infused therein. The flexible fiber-reinforced ceramic composite defines a flowpath having a three-dimensional cross-section. The cross-section of the flowpath is variable along the length of the flowpath. A plurality of anchors are integrally formed in the fiber preform. The plurality of anchors extend through a thickness of the ceramic matrix. The plurality of anchors are configured to couple to at least one actuator. The at least one actuator is actuatable to vary the three-dimensional cross-section of the flowpath.
