A bonding method for bonding an adherend with a high-frequency dielectric heating adhesive sheet is provided. The adherend includes a fluorine-containing surface at least containing fluorine on a surface thereof. The high-frequency dielectric heating adhesive sheet includes a high-frequency dielectric adhesive layer including a thermoplastic resin and a dielectric filler. A surface free energy of the high-frequency dielectric adhesive layer is in a range from 15 mJ/m.sup.2 to 30 mJ/m.sup.2. A melting point of the high-frequency dielectric adhesive layer is in a range from 110 degrees C. to 300 degrees C. The bonding method includes bringing the fluorine-containing surface of the adherend into contact with the high-frequency dielectric adhesive layer and applying a high-frequency wave to the high-frequency dielectric adhesive layer to bond the high-frequency dielectric heating adhesive sheet to the fluorine-containing surface.

A structural reinforcement for insertion into a cavity of a vehicle structure including a base reinforcing portion, an expandable material and a localized reinforcement is disclosed. The localized reinforcement is placed within the structural reinforcement at a location of anticipated increased deformation during vehicle impact in an effort to reduce deformation and control the load distribution post-impact.

A method of manufacturing a product including at least two carbon parts including the step of: manufacturing a first carbon part, manufacturing at least a second carbon part, providing on a surface of one of the first carbon part or second carbon part a plurality of protrusions including a carbon resin, joining together the first carbon part and the second carbon part in such a way that the plurality of protrusions is interposed between the first carbon part and second carbon part for providing physical and electrical connection is provided.

Adhesive bonds are applied by mixing two adhesives with different properties and dispensing them to form bondlines between substrate pairs. The adhesives are then thermally cured and cooled. Varying the mix ratio permits one to vary the properties of the adhesive mixture so formed for use in bonding many different substrate pairs. The process allows potentially infinite variations of adhesive properties between those of the respective starting adhesives, simply by varying the mix ratio. The invention is especially adapted for use in manufacturing settings in which adhesives are to be applied in multiple places, but differing adhesive properties are needed among the various bonding areas.

A system and method for bonding a first layer of material to a second layer of material includes a first electrically conductive plate, a second electrically conductive plate spaced apart from the first electrically conductive plate. The second electrically conductive plate is electrically grounded. A high frequency generator in electrical communication with the first electrically conductive plate supplies high frequency electrical signals to the first electrically conductive plate. An adhesive applied to one of the first and second layers of material has an electromagnetic susceptor material that when subjected to the electric field heats the adhesive to an adhesive curing temperature to bond the first layer of material to the second layer of material. A clamping mechanism applies pressure to one of the first and second layers of material to maintain contact between the first and second layers until an adhesive cure time has lapsed.

A structural assembly for a recreational vehicle includes a first structural frame member having a wall and a hollow space at least partially defined by the wall and a second structural frame member having a section thereof extended into the hollow space of the first structural frame member forming an internal interface with the wall of the first structural frame member. The assembly further includes a foam material located in the hollow space that fills a portion of the hollow space to thereby form a bearing member adjacent the section to restrict motion of the section relative to the wall and thereby to form an internal connection between the second structural frame member and the first structural frame member at the internal interface to secure the second structural frame member to the first structural frame member to form a recreational vehicle component.

A wearable garment includes a compression fabric with at least one electrode coupled to the compression fabric or sewn into seams of the wearable garment. The electrode includes a first layer comprising a metal integral conductive silicone rubber material configured to lay proximate to a wearer of the garment. The electrode may also include a second layer including a conducting metal sheet and a conductive lead coupled to the second layer. A non-conducting layer is configured to lay proximate to the compression fabric.

An adhesive application device includes a coater and an air conditioning device. The coater includes a roll and a roll temperature control device. The roll has an elongated shape having an axis and outer surface and is rotatable around the axis. The roll holds thermosetting adhesive on the outer surface and applies the thermosetting adhesive to an application surface of a sheet member with the first roll being rotated and contacted with the sheet member. The roll temperature control device is disposed adjacent to the roll and configured to lower temperature of the outer surface of the roll to control viscosity of the thermosetting adhesive held by the roll to be appropriate application viscosity that is appropriate for application to the sheet member. The air conditioning device is configured to adjust temperature and humidity of air in a space near the coater.
