Methods and systems for rapidly testing adhesion

摘要

Adhesion testing systems, methods of fabrication, and methods of testing are disclosed. Test systems include test coupons with non-metallic test adherends. Test coupons are configured to test bonds to the non-metallic test adherends under peeling stress and/or shearing stress. Test methods are simplified and rapid as compared to standard adhesion tests and include methods of accelerated environmental testing. Test methods also are adapted for qualitative and quantitative measurement of bond performance.

主权项

1. A method of testing a quality of a bond to non-metallic materials, the method comprising:
fabricating a layered test coupon by:
adhering a test adherend with a first test adhesive to a first location on a peeling adherend to create a first test bond and adhering the test adherend with a second test adhesive to a second location on the peeling adherend to create a second test bond, wherein the test adherend is laminar, wherein the peeling adherend is laminar, and wherein together the test adherend, the first test adhesive, the first test bond, the second test adhesive, the second test bond, and the peeling adherend form a test structure;bonding the peeling adherend to a first peeling support; andbonding the test adherend to a second peeling support; partially peeling the first peeling support from the second peeling support to test a strength of the first test bond; and partially peeling the first peeling support from the second peeling support to test a strength of the second test bond.
