Abstract
A method is provided to bond panels or other components of metal, preferably aluminium or an alloy thereof, in which adhesive in powdered form is electrostatically deposited on selected areas of the or each panel or component. The powder is fused to the surface in selected areas and the excess removed. Thereafter the panels or components are contacted and bonded together.
Description
SPECIFICATION
Method of, and components for, adhesive bonding
This invention relates to the bonding of panels or other components of metal and to components formed for such bonding. It is particularly, though not exclusively, concerned with panels of aluminium alloy.
The use of adhesives to bond metal and in particular the bonding of vehicle body components using adhesive bonding techniques has been shown to be an attractive alternative to spot welding and to mechanical methods. The advantages to be gained are apparent when considering the nature of the materials to be used in likely future body designs.
A major disadvantage associated with the use of adhesives for the joining of aluminium alloy structural members is the requirement for surface preparation by chemical means in order to obtain satisfactory bonding. The individual treatment of components and the subsequent rigorous control of storage conditions prior to assembly are penalties which seriously undermine the viability of using adhesive bonding extensively in volume production. There is also the problem of applying any adhesive that is chosen. Adhesives in the form of a film are intended for relatively flat surfaces. Adhesives in the form of paste involve the risk of contamination in cosmetically significant areas and can also constitute a health hazard.
According to a first aspect of the present invention there is provided a method of bonding panels, or other components of metal comprising the steps of:
(1) applying an adhesive in the form of a
powder by electrostatic means to a
surface of one or both of two components
to be subsequently bonded together:
(2) using localised fusion of the powder onto
the component surface to retain adhesive
on a selected area of the, or each,
component;
(3) removing excess powder from the
surface of the, or each, component;
(4) contiguously juxtaposing the surfaces of
the components to be joined; and
(5) fusing the adhesive to bond the
juxtaposed components.
According to a second aspect of the present invention there is provided a metal component, for subsequent bonding to another component, comprising a metal fabrication on which an adhesive in the form of a powder has been deposited by electrostatic means and subsequently retained on a predetermined area of the fabrication by local fusion.
The invention takes advantage of the fact that powders are readily applied electrostatically and also allow for a highly controlled method of dispensing with the ability to recover and recycle unused powder following the local fusion step.
It is envisaged that the components would be fabricated and thereafter mounted on jigs: to allow surface treatment immediately prior to powder application; and to enable the components to be juxtaposed rapidly and accurately. Panels having adhesive locally fused to them can be subsequently stored for lengthy periods prior to a subsequent bonding with another component. It is also envisaged that an adhesive film formed by the step of localised fusion could confer durability benefits.
Claims
1. A method of bonding panels, or other components, of metal comprising the steps of:
(1) applying an adhesive in the form of a
powder by electrostatic means to a
surface of one or both of two components
to be subsequently bonded together;
(2) using localised fusion of the powder onto
the or each component surface to retain
adhesive on a selected area of the, or
each, component;
(3) removing excess powder from the
surface of the, or each, component;
(4) contiguously juxtaposing the surfaces of
the components to be joined; and
(5) fusing the adhesive to bond the
juxtaposed components.
2. A metal component for bonding to another component, comprising a metal fabrication on which an adhesive in the form of a powder has been deposited by electrostatic means and subsequently retained on a predetermined area of the fabrication by local fusion.
3. A metal component, as claimed in Claim 2 of aluminium or an alloy thereof.
4. A vehicle body fabricated by a method as claimed in Claim 1.
