Method and apparatus for evaluating or measuring the adhesion properties of a thin layer applied to the rough surface of a substrate or of reinforcement elements of a body made of a composite or aggregate material.

摘要

The method and apparatus evaluates or measures the characteristics of the adhesive properties of a thin layer (1) applied to the rough surface of a substrate (2) or of the reinforcement elements of a body made of a composite material or an aggregate. The apparatus consists of a block (3) made of a deformable material and means (4) providing a permanent or temporary link between the deformable block (3) and the thin layer (1). Means are provided for exerting a force on the deformable block (3), as are means (J1...Jn, 5) for measuring the surface deformations of the deformable block (3). These deformations depend on the properties of the thin layer (1). <IMAGE>
