An FRP panel material includes reinforcing fibers oriented in predetermined orientation directions near the surface. In the surface of the panel material, a plurality of either or both of protrusions and depressions having shapes of congruent regular triangular pyramids are provided. The bases of the regular triangular pyramids are arranged on a virtual reference plane along the surface with no gap or overlap so that each vertex of an equilateral triangle constituting each base is shared by six of the bases as vertices thereof. Each of the orientation directions of the reinforcing fibers is parallel to any lateral edge of each regular triangular pyramid as seen in the thickness direction of the panel material.

A blow-molded plastic frame of a portable collapsible sign includes a first outer portion, a second outer portion spaced apart from the first outer portion, and a pattern of structural stiffening features formed in the first and second outer portions. The pattern comprises rows and columns of first depressions extending from the first outer portion into a hollow interior portion between the first and second outer portions, and rows and columns of second depressions extending from the second outer portion into the hollow interior portion. Each first depression has a first floor comprising three first arms having rotational symmetry. Each first arm is rotated from another first arm by 120 degrees. Each second depression has a second floor comprising three second arms having rotational symmetry. Each second arm is rotated from another second arm by 120 degrees. The first floor of each first depression is aligned with the second floor of an adjacent second depression.

An absorbent article can have a topsheet layer, a liquid impermeable layer, and an absorbent core positioned between the topsheet layer and the liquid impermeable layer. The absorbent article can further include an exudate management layer in fluid communication with the topsheet layer. In various embodiments, the exudate management layer can be positioned on a body facing surface of the topsheet layer. In various embodiments, the exudate management layer can be positioned between the topsheet layer and the absorbent core. The exudate management layer has a first component which defines an opening for direct passage of body exudates into the absorbent core. The exudate management layer has a second component which at least partially overlaps the first component of the exudate management layer and further extends in the longitudinal direction of the absorbent article in a direction towards the posterior region of the absorbent article.

According to some illustrative embodiments, a protective product is provided that includes: at least one expandable slit paper sheet, said at least on expandable slit paper being expanded between opposing ends of said slit paper; a first embossed paper sheet facing said expanded slit paper sheet and a second paper sheet facing an opposite side of said at least one expanded slit paper sheet, at least one of said first embossed paper sheet and said second paper sheet being fixed to said expanded slit paper sheet at the opposing ends of said expanded slit paper sheet and thereby maintaining said expanded paper in its expanded state, said first embossed paper sheet having a plurality of embossings that increase the rigidity of said embossed paper sheet, whereby inhibiting deformation of said embossed paper sheet that is fixed to said expanded slit sheet paper.

Described is a micro-lattice damping material and a method for repeatable energy absorption. The micro-lattice damping material is a cellular material formed of a three-dimensional interconnected network of hollow tubes. This material is operable to provide high damping, specifically acoustic, vibration or shock damping, by utilizing the energy absorption mechanism of hollow tube buckling, which is rendered repeatable by the micro-lattice architecture.

A die tool for forming a C-section component having radiused shoulders, the includes a cylindrical inner die and an outer die having a cylindrical central portion connected to opposing end flanges by respective radiused concave portions. A portion of the inner die is arranged to be disposed between the end flanges of the outer die and spaced apart therefrom to define a cavity corresponding to the desired cross-section of the C-section component to be formed. The radiused convex and concave portions have a radius of curvature that varies about the circumference of the respective inner and outer dies. The inner and outer dies are rotatable such that the radius of curvature of the radiused convex and concave portions where the inner and outer dies are adjacent to one another varies as the inner and outer dies are rotated.

A heat transfer system for use within an avionics bay of an aircraft is provided by the present disclosure that includes, in one form, an aircraft panel comprising an upper skin, a lower skin, and a foam core disposed between the upper skin and the lower skin. At least one heat conducting array extends through the foam core and between the upper skin and the lower skin, the heat conducting array defining at least one upper cap, at least one lower cap, and a wall portion extending between the upper cap and the lower cap, the upper cap being disposed proximate avionics within the avionics bay. A heat conducting spreader is disposed between the lower cap of the heat conducting array and the lower skin of the aircraft panel.

An outer cover for an absorbent article includes a nonwoven component having a plurality of apertures formed therein and a film bonded to the apertured nonwoven component. The apertures in the nonwoven component are formed by needling prior to the film being bonded to the nonwoven component. A method of making the outer cover includes feeding a web of nonwoven material to a needling station, needling the web of nonwoven material to form a plurality of apertures therein to define an apertured web of nonwoven material, and bonding the apertured web of nonwoven material to a film.
