  • Publication number: 20040163771
    Abstract: A method for adhesively joining two members includes the steps of mixing non-compressible beads with an adhesive, applying the resulting mixture to one of the members and hemming one member over the other in overlapping relationship. Apparatus for performing this method includes a container for containing a mixture of an adhesive and a plurality of non-compressible beads, an applicator for applying the mixture to one of the members, and hemming means for hemming one member over the other in overlapping relationship. A metering device for dispensing adhesive fluid is constructed with a dispensing rod having a cooling means for facilitating operation of the metering device. The present invention finds particular utility in bonding together the inner and outer panels of an automotive door assembly.

  • Patent number: 6060155
    Abstract: The present invention provides a material forming tool, such as a sheet metal stamping die, having a polymer matrix and filler material mixed therein. The filler material is a plurality of microspheres which are coated with a release agent. The coating of the release agent should be sufficient to allow the microspheres to rotate in the polymer matrix when the tool is used to form material.

  • Patent number: 5820801
    Abstract: A method and apparatus for binding the fibers of, and forming a fiber reinforced plastic structure. A fiber reinforced plastic preform is created by depositing a mixture of reinforcing fibers, binding fibers and resin matrix fibers on a screen having a preselected geometry. The fiber reinforced plastic preform is exposed to high temperature fluid causing the binding fibers to melt and, thereafter, to cool air to temporarily bind the preform in a tackified state. The tackified preform is exposed to a higher temperature fluid causing the resin matrix fibers to melt and, thereafter, to cool air to solidify and thus bind and lock the reinforcing fibers of the tackified preform in place to create a homogeneous fiber reinforced plastic structure.

  • Patent number: 5814256
    Abstract: A method and apparatus of producing and using composite fibers in a liquid molding process. The composite fibers are formed from a base material and filler particles which are lighter or less expensive than the base material. A preform screen is placed at the bottom of a tank. The tank is filled with liquid, the composite fibers and a mass of reinforcing fibers creating a slurry above the screen. The screen is raised up through the slurry causing the composite fibers and the reinforcing fibers to be deposited on the screen creating a fiber preform. The preform is then removed from the screen and is placed in a mold for use in a liquid molding process.

  • Patent number: 5795443
    Abstract: An apparatus for making fiber reinforced preforms using a wet slurry process wherein the flow of liquid through portions of a screen having a predetermined configuration is selectively controlled. The selective control of the flow of liquid through the portions of the screens regulating the quantity of fibers deposited on the selected portions of the screen thereby controlling the thickness of the fiber preform at the selected portions of the screen.

  • Patent number: 5783298
    Abstract: A container having a mixture of one part of a two-part epoxy adhesive with a plurality of glass beads pre-mixed therein. The concentration of beads in the final mixture as applied to the joint to be bonded is in the range of about 5% to about 20% by weight, with the beads having a diameter in the range of 0.003 to about 0.030 inches. The mixture is capable of being pumped from the container and applied to a member for forming a hem flange joint with another member. The adhesive/glass beads mixture finds particular utility to help prevent excess squeeze out and promote reliable bonds in processes in which an inner and outer panel of an exterior automotive closure member are joined together by way of a hem flange.

  • Patent number: 5770016
    Abstract: A method and apparatus for binding the fibers of a fiber reinforced plastic preform. A fiber reinforced plastic preform is created in a preselected geometry from a mixture of reinforcing fibers and binding fibers, the binding fibers being responsive to a high frequency electromagnetic field to melt thereby binding the reinforcing fibers. The fiber reinforced plastic preform is then exposed for a short period of time to a high frequency electromagnetic field, with the high frequency electromagnetic field causing the binding fibers to melt thus binding the reinforcing fibers of the preform.

  • Patent number: 5685956
    Abstract: A method and apparatus for binding the fibers of a fiber reinforced plastic preform. A fiber reinforced plastic preform is created in a preselected geometry from a mixture of reinforcing fibers and binding material. The fiber reinforced plastic preform is sequentially exposed to high temperature steam and cool air causing the binding material first to melt and, thereafter, to solidify thus binding and locking the reinforcing fibers of the preform in place. The fiber reinforced plastic preform is ejected from the apparatus by air pressure and is retrieved by any suitable method.
