Abstract:

The basic mechanisms of degradation of organic polymers at elevated temperatures in contact with certain metals was investigated. The areas of study included migration of metal into polymers, the role of metal oxide films in degradation, polymer-metal reactions, and inhibition of degradation by the use of inert metal coatings. The polymers considered were epoxies, phenolics, and polybenzimidazole. The metals used were aluminum, iron, and stainless steel. Composite configurations evaluated were lap shear specimens and fine metal powders dispersed in the polymers. The experimental techniques used were mass spectrometry, neutron activation analysis, infrared absorption, electron paramagnetic resonance, thermochemiluminescence, and vapor phase chromatography.
