Abstract
An apparatus and method for testing adhesion of a laminate, particularly a foam-film laminate, includes an inclined ramp to which the laminate is secured with an adhesive element and a weight that travels down the ramp and over the laminate and adhesive element. After the weight has been applied, the adhesive element is removed and the percentage separation of laminate layer(s) from the laminate surface is assessed. The weight may be a roller that is guided with a guide element along its path of travel.
Claims20
An apparatus for testing adhesion of a laminate, comprising:
- a weight;
- and
- a ramp having at least one inclined section adapted for securing thereon a laminated specimen and defining a path of travel for the weight.
A method for testing adhesion of a laminate, comprising:
- securing a laminated specimen onto at least one inclined section of a ramp with an adhesive element that contacts a surface layer of the laminated specimen, said inclined section defining a path of travel for a weight;
- causing the weight to move along the path of travel from a first ramp height to a second ramp height lower than the first ramp height and over the laminated specimen;
- and
- removing the adhesive element from the laminated specimen.
