A method for adhesively bonding a first body to a second body, the first body comprising a non-metallic substrate, such as a piece of rubber, or comprising a non-metallic substrate and a filler therein, such as a piece of fiberglass reinforced plastic, the second body comprising any type of substrate, such as a piece of glass, plastic or metal. The first body is pretreated by placing it in the path of an energy beam, such as a laser beam, to form projections on the non-metallic substrate by evaporation of the non-metallic substrate of the first body, or to expose filler by evaporation of the non-metallic substrate of the first body. The second body can be untreated, pretreated as above or pretreated another way, such as by solvent washing or sandblasting. An adhesive is then coated on the pretreated area of the first body and the first body adhered to the second body. The cured adhesive interlocks with the projections and/or the exposed filler to produce a stronger bond. Similarly, an object, such as a rubber gasket, can be molded to a so-pretreated body so that the cured molding compound interlocks with the projections and/or the exposed filler to produce a stronger bond between the molded object and the so-pretreated body. The invention is also an article made by the method.
