The object of this study was to analyze the complex degradation history of a heat‐resistant epoxy resin laminate using the mechanical–chemical equation of state. A further object was to determine if weight‐loss measurements at elevated temperatures could be used to predict long‐term rupture strength. Master rupture curves drawn by using a second‐order parametric form of the equation of state largely clarified the anomalous behavior of the laminate. It was not found possible to predict the longterm mechanical properties from weight‐loss data although there was evidence of some correlation.
