Abstract
In a method of setting a hot set adhesive, the adhesive is set by passing an electric current through an electric heating element embedded in the adhesive. Also disclosed is an article of manufacture comprising a web e.g. of glass fibre, impregnated with a hot set adhesive and into which is incorporated a heating element which may be energised to set the adhesive.
Description
SPECIFICATION
Method of bonding substrates using hot set adhesives and compositions for use therein
This invention relates to a method of bonding substrates using hot set adhesives and a composition for use therein.
Hot set adhesives are known and are described for example in US Patents 2879252, 2920990 and 3280217. In use a layer of the hot set adhesive is placed between the substrate layers to be bonded and then heating to set the adhesive. The adhesive may be raised to the setting temperature by a variety of methods ranging from placing the whole assembly in an oven, infra-red heating to microwave heating. All such methods show one disadvantage or the other, for example, that the bonded structure is much too large to be heated in an oven or that the adhesive layer cannot be effectively and uniformly heated by infra-red or microwave means. Moreover, limitations are often imposed by the thermal stability of the substrates themselves which may well have thermal degradation temperatures below the setting temperature of the adhesive.
In accordance with the present invention a method of bonding substrates with a hot set adhesive is provided which substantially eliminates many of the above-mentioned disadvantages and which provides for a rapid and uniform heating of the adhesive layer even over relatively large areas, often without substantially raising the temperature of the substrate materials. In accordance with the invention this is achieved by locating between the surfaces to be bonded a woven or non-woven fabric, e.g. of glass fibre, having a heating element incorporated in the structure of the fabric, impregnating the hot set adhesive into the fabric, super-imposing the substrate layers to be bonded on the impregnated fabric, and finally passing a current through the heating element to effect heating of the adhesive impregnant to the setting temperature.
As will be appreciated, the technique can be employed to both large and small areas of adhesive, but is particularly suitable for large areas, since substantially uniform heating and setting of the adhesive can readily be obtained. Also there is only limited heating of the substrate materials themselves, so that the method of the invention permits materials to be bonded using hot set adhesive which have not previously been bondable by such adhesives owing to low heat stability.
Also provided in accordance with this invention, is a hot set adhesive system comprising a fabric, e.g. of glass fibre, having a heating element incorporated into the structure of the fabric, and said fabric being impregnated with a hot set adhesive composition.
The hot set adhesive system as described may be supplied in a range of different forms e.g. as hot set adhesive impregnated tapes, hot set adhesive im
pregnated sheets etc. ready for use in the method of this invention.
As will be apparent, any suitable hot set adhesive
may be used in accordance with this invention and any suitable fabric, but preferably and usually the fabric will be of woven glass fibre with the heating element incorporated into the weave.
In a broader aspect of the present invention, the method of the invention can be modified by simply embedding a heating element in the layer of hot set adhesive between the surfaces to be bonded, i.e.
without the fabric, and energising the element to effect setting of the adhesive. It is preferred, however, to use a fabric matrix for the adhesive as above described, since this, in particular, results in uniformity of heating of the adhesive.
CLAIMS (Filed on 2.11.82.
1. A method of bonding two surfaces together which comprises interposing between said surfaces a layer of hot set adhesive, and heating said layer to set the adhesive, wherein the adhesive is set by means of an electric current fed through an electric heating element embedded in said layer.

3. A method according to claim 2, in which the web is a woven or non-woven web of glass fibres.
4. As an article of manufacture, a web of fibrous reinforcement material impregnated with a hot set adhesive and into the structure of which is incorporated an electrical heating element by means of which the adhesive can be heated and caused to set upon the passage of an electric current through the heating element.
5. An article according to claim 4, wherein said web is a woven or non-woven web of glass fibre.
