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.

The method for manufacturing a container having a substantially stiff outer container and a readily deformable inner bag of thermoplastic plastic materials which do not form a weld connection with one another, with a container opening and holes in the outer container, wherein the method includes forming holes in the wall of the outer container at diametrically opposed positions, which lie on the intersection line of a plane defined by the base seam and the longitudinal axis of the container with the container wall and that a pin-shaped tool forces the inner bag through the holes by a predetermined distance from the wall of the outer container and thereby detaches it from the wall, whereafter a pressure medium is introduced through the holes into the gap between the inner bag and the outer container, which detaches the inner bag from the wall of the outer container.

A method of forming a trim panel is provided. The method includes the steps of: heating a non-woven material to a predetermined temperature; applying a decorative film having perforations to a first surface of the heated material to create a bilaminate; placing the bilaminate layer into a cavity of a tool such that the decorative film is facing the cavity; heating the cavity; and injecting a thermoplastic resin into the tool such that the thermoplastic resin is adhered to a second surface of the material, the second surface being opposite to the first surface.

The present invention relates to breathable, vented, and insulating cold weather garments. More particularly, the present invention relates to garments with chambers to retain an insulating fill material. Perforations along the seams between the insulating chambers may achieve optimal evaporative moisture transfer from the inside (proximal to the body of a wearer) of the garment to the outside environment.

The present invention relates to a method for manufacturing a polymer sheet for use as an immobilization element, wherein the sheet is at least partly made of a polymer material comprising a polymer from the group of polycaprolactone, a copolymer of polyethylene with at least one -olefin having 3-10 C atoms, or a mixture of two or more of the aforementioned polymers, a photo-initiator, and a photo-cross-linker, wherein the polymer sheet has a thickness of 1.0 to 5 mm and wherein the polymer sheet is at least partially cured by exposing to UV radiation for the at least partially cross-linking of the polymer.

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.

An apparatus for perforating a carbon fiber substrate material comprises a support structure including a first side support and a second side support and a cylindrical anvil rotatably connected between the first side support and the second side support. The anvil is configured to move the carbon fiber substrate material in response to rotation of the anvil. The apparatus further comprises a cylindrical cutting wheel rotatably connected to the support structure between the first side support and the second side support and positioned adjacent to the anvil. The cutting wheel includes a plurality of blades projecting outward from an outer surface of the cutting wheel wherein the blades of the cutting wheel are configured to perforate the carbon fiber substrate material when the carbon fiber substrate material moves between the anvil and the cutting wheel.

A method of anchoring a connector in a first object includes providing the connector, the connector having a liquefiable material that is liquefiable by mechanical vibration, such as a thermoplastic material, bringing the connector into contact with low density layer that has an arrangement of discrete elements and gas-filled (empty) spaces between the discrete elements, pressing the connector against the low density layer and coupling mechanical vibration energy into the connector to cause the connector to penetrate into the low density layer to deform the discrete elements, until a flow portion of the liquefiable material becomes flowable and is caused to interpenetrate spaces between the deformed discrete elements so that an intertwined structure of the liquefiable material and the deformed discrete elements results, and stopping the mechanical vibration energy and causing the flow portion to re-solidify to anchor the connector in the low density layer.

A method of reinforcing a fiber reinforced resin matrix composite structure, the method including: providing a composite structure having one or more holes formed therein, and feeding a reinforcement rod through a passageway having one or more walls defining an inlet to the passageway. The inlet to the passageway is dimensioned to prevent a rod having a maximum cross sectional dimension greater than a predetermined dimension from passing through the passageway. In the event of the rod impacting the wall defining the inlet to the passageway, operation of the rig is stopped. In the event of the rod passing through the passageway without impacting the wall defining the inlet to the passageway, a portion of the rod is inserted into a hole in a composite structure.

A method for joining a first component and a second component. The method includes forming a first bond between the first component and the second component by providing a plurality of projections on the first component and embedding the plurality of projections in the second component; creating a fastener hole which passes through the first component and the second component and which encompasses at least one of the projections; and forming a second bond between the first component and the second component by installing a fastener in the fastener hole.
