Abstract

Peeling stress is experimentally shown to be an important factor for delamination in thermally mismatched bimaterial assembly. Strips of the plastic ULTEM-1000 and nickel alloy Kovar were attached with Devcon 14200 epoxy, and the temperature was raised from the stress-free curing temperature for one set of samples, and lowered for another set of samples, resulting in interfacial stresses. The samples that delaminated had the highest peeling stress.
