Measuring the Temperature Dependence of the Strength of Metal-Polymer Joints

Source

The method of measuring the temperature dependence of adhesion characterized by peel strength, which is based on the application of the temperature gradient in the plane of adhesive contact, is discussed. The foil is peeled in the direction of the temperature gradient. In this case the adhesiogram is the temperature dependence of peel strength. The method determines in a simple way the dependence of the strength of adhesive metal-polymer joints on the test temperature for a wide temperature range. The gradient method has been employed to study the effect of the test temperature (250 to 390 K) on the adhesion of amorphous and crystalline polymers to aluminum. The temperature dependence of adhesion in the case of amorphous polymers to the metal is described by a curve with the maximum at 15 to 35 K higher than the polymer glass transition temperature. The strength of adhesion in the case of crystalline polymers is lower than that of amorphous ones, and decreases with increasing test temperature.
