Abstract: A sheet material (1) includes a stiffness-increasing concave-convex part (20). A first reference plane (K1), an intermediate reference plane (K3), and a second reference plane (K2) serve as a reference system. The intermediate reference plane is partitioned by first lattice straight lines (L1), second lattice straight lines (L2), and third lattice straight lines (L3) so as to define hexagonal unit areas (24) and triangular unit areas (25) in the intermediate reference plane. Areas that include a plurality of the hexagonal unit areas and the triangular unit areas are designated as first, second and third reference areas (214, 224, 234), respectively. Combinations thereof constitute new first, second and third reference areas (213, 223, 233), respectively. The concave-convex part includes first areas (21) and second areas (22), which respectively include the new first reference areas and the new second reference areas, and third areas (23), which include the new third reference areas.

Abstract: A coupon geometry that reliably fails in the gauge area of the coupon during fatigue testing. The propensity to fail at the gauge area is imparted by using a bow-tie-shaped coupon coupled with similarly shaped tabs. The test coupons have a bow-tie-shaped profile with tapered sides that converge as they extend from the opposing ends of the coupon to the gauge area, forming a pair of trapezoidal portions (one the mirror image of the other) connected by the gauge area. These trapezoidal portions of the test coupon include the regions where similarly trapezoidal tabs will be adhered to the front and back of the coupon. The test coupon has a minimum width in the gauge area and a constant thickness, and a height of the gauge area is no greater than 3% of a height of the test coupon.

Abstract: A screen has a plurality of rods arranged longitudinally around a central axis. The rods have first and second edges (e.g., inner and outer edges). Each of the first edges defines a profile that varies in lateral distances from the central axis along a longitudinal length of the rod. For example, the first edges can have an undulating profile of crests and troughs. With the plurality of rods disposed around the central axis, the profile produces a varied surface on the screen when a plurality of wraps from one or more wires is disposed laterally around rods. These one or more wires attach to the first edges of the rods and form a plurality of gaps.

Abstract: Described herein are various methods for making textured articles, textured articles that have improved fingerprint resistance, and methods of using the textured articles. The methods generally make use of masks comprising nanostructured metal-containing features to produce textured surfaces that also comprise nanostructured features. These nanostructured features in the textured surfaces can render the surfaces hydrophobic and oleophobic, thereby beneficially providing the articles with improved fingerprint resistance relative to similar or identical articles that lack the texturing.

The top panel portion includes a recessed portion that is curved so as to have an arc shape in a direction opposite to a direction in which the bent portion is curved.

Abstract: The cellular cushioning article comprises a thermoformed film bonded to a second film, with the thermoformed film having thermoformed regions separated by a land area. The thermoformed film has a combination of (i) a layer containing a high melt point polymer and (ii) thermoformed regions exhibit a high average maximum birefringence. The high birefringence corresponds with high stress on the polymer chains. The combination results in cells of substantially increased burst strength. The cellular cushioning article can provide higher burst strength per mil of film thickness, or can be produced using less plastic than prior art cellular cushioning articles, while maintaining the same or comparable burst strength. Also disclosed is a process for making the cellular cushioning article.

Abstract: A second mold is placed on a planar surface of a first mold to form a first mold cavity, which is filled with a first material slurry containing a first material powder and the molded slurry is caused to set, thereby forming a first molded part on the planar surface of the first mold. A third mold is placed on the planar surface of the first mold from which the second mold is removed and on which the first molded part is formed, thereby forming a second mold cavity. The second mold cavity is filled with a second material slurry which contains a second material powder different from the first material powder so as to mold the slurry in contact with the first molded part. The molded slurry is caused to set, thereby forming a second molded part on the planar surface of the first mold.
