PILE WEATHERSTRIPPING AND OTHER PILE AND BRUSH ARTICLES HAVING PILES OR BRUSHES EXCLUSIVELY OF POLYAMIDE (NYLON) REACTIVELY BONDED TO AN UNLIKE PLASTIC MATERIAL ESPECIALLY POLYPROPYLENE
Pile articles (20,22), especially pile weather stripping, and a method and apparatus (10) for making such articles where the backing (24) and the pile (26) are of unlike material, especially nylon yarn for the pile (26) and polypropylene containing material for the backing (24), wherein prior to the welding of the pile (26) to the backing (24) the pile is first pre- heated using ultrasonic energy to melt the pile in a region (65) thereof where the pile is ultrasonically welded to the backing and before the weld is made. The ultrasonic melting occurs upstream of the location where the pile (26) is welded to the backing (24) so that the ultrasonically pre-heated melted region (65) of the pile (26) can cool and become at least partially solidified. Then pile (26) at the pre-heated melted region (65) is welded to the backing (24) and causes a reactive or chemical weld to occur, thereby attaching the pile (26) to the backing (24).
Methods and assemblies for forming features in composite components
Various methods and assemblies are provided for producing composite components having formed in features. For example, a method may comprise depositing a composite material on a base tool; aligning an aperture forming tool with a tooling aperture in the base tool; inserting the aperture forming tool through the composite material to form an aperture in the composite material; deploying a feature forming tool to press the composite material into one or more recesses; and processing the composite material with the feature forming tool in contact with the composite material. In some embodiments, the feature forming tool includes a stem extending through the composite material and into the base tool, as well as a feature forming head that is brought into contact with and processed with the composite material. In other embodiments, a tooling assembly holds a pin in place during processing to fix the pin in the composite component.
Pile weatherstripping and other pile and brush articles having piles or brushes exclusively of polyamide (nylon) reactively bonded to an unlike plastic material especially polypropylene
Pile articles (20,22), especially pile weatherstripping, and a method and apparatus (10) for making such articles where the backing (24) and the pile (26) are of unlike material, especially nylon yarn for the pile (26) and polypropylene containing material for the backing (24), wherein prior to the welding of the pile (26) to the backing (24) the pile is first pre-heated using ultrasonic energy to melt the pile in a region (65) thereof where the pile is ultrasonically welded to the backing and before the weld is made. The ultrasonic melting occurs upstream of the location where the pile (26) is welded to the backing (24) so that the ultrasonically pre-heated melted region (65) of the pile (26) can cool and become at least partially solidified. Then pile (26) at the pre-heated melted region (65) is welded to the backing (24) and causes a reactive or chemical weld to occur, thereby attaching the pile (26) to the backing (24).
LASER SURFACE TEXTURE FOR ADHESIVE BONDING OF METALS
A joined article includes a first metal piece with a first bonding surface, having one or more recessed areas, a second metal piece with a second bonding surface with the second bonding surface having one or more recessed areas, and an adhesive layer between the first bonding surface of the first metal piece and the second bonding surface of the second metal piece. The adhesive layer occupies a space between the first and second bonding surfaces and occupies the recessed areas of both the first and second bonding surfaces of the first and second metal pieces.

Fluid leak repair kits are described comprising a putty, self-amalgamating tape, and a composite material for use in encompassing the self-amalgamating tape. The composite material comprises a flexible sheet or tape and a matrix component for binding the flexible sheet or tape. The matrix component comprises a resin or water-activated matrix component which, when cured, forms an outer shell.
Methods and process for producing polymer-metal hybrid components bonded by C—O-M bonds
Methods of producing polymer-metal hybrid components that are bonded by CO-M bonds at the interface using at least one of the hot pressing, rolling, and injection molding methods to create chemical bond formation conditions at the polymer and metal interface. When the thermal cycle and compressive pressure specified herein is combinationally created at the polymer and metal interfaced, strong CO-M bonds forms at the interface and strongly bonds the metal and polymer together through the reaction carbonyl groups (CO) in polymer and the metal surface. For polymers lacking enough carbonyl groups, new functional groups can be in-situ generation through introducing distributed air pockets at the polymer-metal interface for forming 3-dimensional distributed CO-M bonds at the interface.
POROUS STRUCTURE AND METHODS OF MAKING SAME
The present disclosure provides methods to improve the properties of a porous structure formed by a rapid manufacturing technique. Embodiments of the present disclosure increase the bonding between the micro-particles 5 on the surface of the porous structure and the porous structure itself without substantially reduce the surface area of the micro-particles. In one aspect, embodiments of the present disclosure improves the bonding while preserving or increasing the friction of the structure against adjacent materials.
THERMOPLASTIC TRUSS STRUCTURE FOR USE IN WING AND ROTOR BLADE STRUCTURES AND METHODS FOR MANUFACTURE
The present disclosure generally relates to thermoplastic truss structures and methods of forming the same. The truss structures are formed using thermoplastic materials, such as fiber reinforced thermoplastic resins, and facilitate directional load support based on the shape of the truss structure. In one example, multiple two-dimensional patterns of fiber reinforced thermoplastic resin are disposed on one another in a saw tooth pattern, sinusoidal pattern, or other repeating pattern, and adhered to one another in selective locations. The two dimensional patterns may then be expanded in a third dimension to form a three-dimensional, cross-linked truss structure. The three-dimensional, cross-linked truss structure may then be heated or otherwise treated to maintain the three-dimensional shape.
