Problems solved by technology

Adhesives may also have difficulty bonding non-planar or discontinuous surfaces or when bonding multiple components that share a common joint
Furthermore, the bonding of multiple planes can lead to adhesive smearing as the components are assembled together

Embodiment Construction

[0010] The invention includes methods of bonding two or more elements to form a bonded article. The method includes placing two or more components relative to each other in their intended assembly positions to create a joint cavity, filling the cavity with an adhesive, and at least partially curing the adhesive.

[0011] With reference to FIGS. 1 a and 1 b , the method includes placing a first element 10 and a second element 12 relative to each other to form a joint cavity 14 . During the placing step or once the elements are placed, the elements may or may not be in contact with each other. During the injection and curing of the adhesive, the relative movement of the components can be restricted by the use of clips, rivets, screws, snap fits or other mechanical fastening means. Spaced apart ribs or protrusions may be used on one or both elements to maintain joint thickness. The bonding cavity 14 is then filled with adhesive 16 . The joint cavity may be filled through an en...

Abstract

The present invention includes methods of bonding two or more components to form a unitary article. The methods involve placing the components in their final assembled position to create a joint cavity, filling the cavity with an adhesive, and curing the adhesive so that it can be handled without dissociating the components. The invention also relates to articles formed by the disclosed methods.

Description

[0001] priority claim [0001] This application claims the benefit of US Provisional Application No. 60 / 657,147, filed February 28, 2005, which is hereby incorporated by reference. technical field [0002] Generally, the present invention relates to bonding components, and more particularly to bonding components together to form articles for use in automobiles. Background technique [0003] Historically, manufacturing techniques for article fabrication have included the manufacture of separate components and the use of fastening mechanisms to join the components. Typically, fastening mechanisms include mechanical fasteners (eg, rivets, screws, nuts and bolts, snap-fit ​​devices, or the like) and adhesives. However, these fastening mechanisms have disadvantages. For example, many traditional adhesives have difficulty bonding dissimilar materials together (for example, bonding plastic to metal or bonding two dissimilar plastics), or require several steps (for example, primin...
