ABSTRACT:
The method comprises applying on the surface of each of the parts a thin layer of a curable first mixture containing a first resin which cures slowly and is slightly exothermic and has a good adherence to said surfaces. A curable second mixture is then introduced in a space defined by the layers of the first mixture in the final position of the two parts. The second mixture contains a second resin which cures rapidly and is sufficiently exothermic to promote the curing of the first resin and normally has after curing a poor adherence to said surfaces but a good adherence to the first resin.
