Provided are stiffened stringer panels with integrated indexing stacks. An example composite panel comprises a skin member having an inner surface. An index for positioning a support tool comprises a first set and second set of layered laminate stacks coupled to the inner surface such that a channel is formed between the first and second set of layered laminate stacks. The first and second set of layered laminate stacks is configured to cradle a support tool in the channel to automatically align the support tool relative to the panel. A stringer may include a cap portion that extends from the first set to the second set of layered laminate stacks to form flange portions on the inner surface of the skin member. The index and the skin member may be co-cured or co-bonded.

A composite material with an insert-molded attachment steel is provided. The composite material includes a plurality of burring apertures, each of which has a flange in one direction on the attachment steel and is inserted between fibers. A resin is then introduced between the fibers in each burring aperture and external to the flange.

A hydro-formed film includes a polymeric web having a first substantially planar surface and a second substantially planar surface opposite the first substantially planar surface, and a plurality of three-dimensional micro-apertures extending from the first substantially planar surface. The plurality of three-dimensional micro-apertures have a mesh count in a range of about 40 to about 75 apertures per linear inch. The hydro-formed film has a Compression Sensor Point (CSP) count of at least about 80.

A breathable and waterproof composite fabric includes a fabric sheet and a waterproof plastic film. The fabric sheet has a first surface, a second surface and a plurality of micropores extending through the first and second surfaces. The waterproof plastic film is made of a non-porous material and has an outer surface, an inner surface bonded to the first surface, and a plurality of hollow protrusions protruding from the outer surface. Each of the hollow protrusions defines a channel having an inner open end at the inner surface and an outer open end distal from the inner and outer surfaces. A method of making the breathable and waterproof composite fabric is also provided.

In an embodiment, a hybrid structure having suspension quality, comprises a core member having an outer surface, a reducible-volume layer associated with the outer surface of the core member and having a reducible volume at least at a number of regions thereof, and a covering layer having an exterior and an interior surface and connected to the core member via the reducible-volume layer by a connection arrangement.

A vehicle interior component is disclosed. The component may comprise a base comprising an opening and first and second layers extending through the opening. The first and second layers may form a structure extending through the opening to an extended position. The first layer may engage the second layer to form the structure. The first layer may separate from the second layer when retracted into the base. The structure may comprise a protrusion formed by the first layer with the second layer to move from a retracted position to the extended position. The protrusion may extend beyond the base by a first distance when the protrusion is retracted and by a second distance greater than the first when the protrusion is extended. The second layer may comprise a bottom; the first layer may comprise a top to couple to the bottom to form the structure as the structure extends.

A composite element for the realization of protection devices of parts of the human body includes a matrix, a reinforcing element, at least partially embedded in the matrix, wherein the reinforcing element has at least one opening shaped so as to define an undercut between the matrix and the reinforcing element, such undercut being suitable for determining a mechanical constraint between the matrix and the reinforcement element.

A method of processing a polymeric web includes providing a forming screen configured for supporting and moving with the web in a machine direction. The forming screen has a plurality of elliptical screen openings, each having a major axis perpendicular to the machine direction and a minor axis parallel to the machine direction. The method includes continuously depositing the web onto the forming screen and passing the web and forming screen through a water stream having a pressure level sufficient to cause the web to be forced into the screen openings, thereby forming protrusions extending from the planar surface of the web. Each protrusion has an apex, an opening at the apex, and an elliptical cross-section parallel to the planar surface of the web. The elliptical cross-section has a protrusion axis ratio that may be selected so as to produce a desired protrusion axis ratio.

A stringer may include a cap portion that extends from the first set to the second set of layered laminate stacks to form flange portions on the inner surface of the skin member. The index and the skin member may be co-cured or co-bonded.

A solid-lubricated metal cutter and processing method relates to the technical field of metal cutters. A surface texture morphology is worked out on a metal cutter, a solid lubricant is filled into the surface texture morphology, and a convex dam is arranged on the cutter surface on which surface texture morphology is located at a chip flow side. The surface texture morphology has micro-pit and micro-boss features, and can exert antifriction effect of a solid lubricant and anti-adhesion effect of micro-protrusions. The convex dam is arranged at an end of the micro-texture region away from the cutting blade, so that a part of the solid lubricant flows back to the texture region and thereby the utilization efficiency and retentiveness of the solid lubricant are improved.
