  • Vehicular structural members and method of making the members
    Patent number: 7838100
    Abstract: The present invention is an article comprising a shaped rigid foam part; a heat activated foamable adhesive applied directly to at least a portion of the outer surface of the shaped foam part and an integral locating means. A second aspect of the invention is a method of forming a foam filled vehicle hollow member comprising, (a) inserting into a vehicular hollow member a rigid foam part comprised of a rigid foam having a heat activated foamable adhesive on at least a portion of the rigid foam insert and at least one integral locating means extending from a surface of the rigid foam, (b) engaging the locating means with the hollow member to locate the rigid foam part within the hollow member, and (c) heating the hollow member having the rigid foam part therein to a temperature and for a time sufficient to activate the heat activated expandable adhesive to form the foam filled vehicle hollow member.
    Type: Grant

  • Injectable structural adhesive
    Patent number: 7360552
    Abstract: Injectable structural adhesives, methods of using the same, and products formed therewith, are described. The adhesive is introduced through a first opening into an internal cavity formed between two or more components. The adhesive is then permitted or forced to flow through the internal cavity, substantially filling the cavity, until it reaches a second spaced opening. Any air contained within the internal cavity is removed by the flow of the adhesive.

  • Vehicular structural members and method of making the members
    Patent number: 7097794
    Abstract: The present invention is an article comprising a shaped rigid foam part; a heat activated foamable adhesive applied directly to at least a portion of the outer surface of the shaped foam part and an integral locating means. A second aspect of the invention is a method of forming a foam filled vehicle hollow member comprising, (a) inserting into a vehicular hollow member a rigid foam part comprised of a rigid foam having a heat activated foamable adhesive on at least a portion of the rigid foam insert and at least one integral locating means extending from a surface of the rigid foam, (b) engaging the locating means with the hollow member to locate the rigid foam part within the hollow member, and (c) heating the hollow member having the rigid foam part therein to a temperature and for a time sufficient to activate the heat activated expandable adhesive to form the foam filled vehicle hollow member.
