Title: METHOD OF ACTIVATING ADHESIVES
Abstract:
According to an aspect of the invention, a method of fastening a second object to a first object is provided, the method comprising: - Providing the first object comprising an attachment surface; - Providing the second object; - Placing the second object relative to the first object, with a resin composition in between the attachment surface and the second object, wherein the resin composition comprises a resin in a flowable state, the resin having a first viscosity; - Pressing the second object and the first object against each other and causing mechanical vibration to act on the second object or the first object or both, until the resin composition is subject to a vibration induced activation, Wherein the activation comprises at least one of reduction of the viscosity of the resin compared to the first viscosity, and of an activation of particles dispersed in the resin, - Continuing or repeating the step of pressing and causing mechanical vibration to act until the resin has at least partially cross-linked and the viscosity of the resin is increased compared to the first viscosity, - Whereby the resin composition secures the second object to the first object.
