Abstract
An adhesive-bonded attachment device includes a mounting base including a mounting surface, a structural adhesive disposed on the mounting surface, and a pressure-sensitive adhesive disposed on the mounting surface bordering the structural adhesive, wherein the structural adhesive and the pressure-sensitive adhesive define a bonding surface configured to be bonded to a contact surface of a structure, and an attachment feature disposed on said mounting base.
Claims20
An adhesive-bonded attachment device comprising:
- a mounting base comprising:
- a mounting surface;
- a structural adhesive disposed on said mounting surface;
- and
- a pressure-sensitive adhesive disposed on said mounting surface bordering said structural adhesive,
- wherein said structural adhesive and said pressure-sensitive adhesive define a bonding surface configured to be bonded to a contact surface of a structure;
- and
- an attachment feature disposed on said mounting base.
An adhesive-bonded attachment device comprising:
- a mounting base comprising:
- a mounting surface;
- a pressure-sensitive adhesive disposed on said mounting surface, wherein said pressure-sensitive adhesive and a portion of said mounting surface define a cavity;
- and
- a structural adhesive disposed within said cavity and bordered by said pressure-sensitive adhesive,
- wherein said structural adhesive and said pressure-sensitive adhesive define a bonding surface configured to be bonded to a contact surface of a structure;
- an attachment feature disposed on said mounting base, wherein said attachment feature comprises a fastening fixture opposite said mounting base;
- and
- at least one pressure exhaust port extending through said mounting base to said cavity, wherein said pressure exhaust port maintains positive pressure on said structural adhesive when said pressure-sensitive adhesive is bonded to said contact surface of said structure.
A method for attaching an article to a structure, said method comprising:
- seating a mounting base of an adhesive-bonded attachment device upon said structure such that a bonding surface of said mounting base engages a contact surface of said structure, wherein said mounting base comprises:
- a mounting surface;
- a pressure-sensitive adhesive disposed on said mounting surface, said pressure-sensitive adhesive and a portion of said mounting surface defining a cavity;
- and
- a structural adhesive disposed within said cavity and bordered by said pressure-sensitive adhesive, said structural adhesive and said pressure-sensitive adhesive defining said bonding surface;
- applying an external force to said mounting base;
- bonding said pressure-sensitive adhesive to said contact surface of said structure;
- applying a clamping force to said structural adhesive;
- curing said structural adhesive;
- permanently bonding said structural adhesive to said contact surface of said structure;
- and
- attaching said article to a fastening fixture disposed on an end of a post extending from said mounting base.
