Zusammenfassung:	The aging mechanism of phenolic resin‐nitrile butadiene composites has been investigated. Using solvent extraction and chromatographic analysis of the extract using dual detectors it was shown that the rubber component was well crosslinked. The phenolic component however was not fully crosslinked, although it would have been expected from the cure conditions employed. With increased time, at temperatures near ambient, the phenolic resin continued to react and caused increased brittleness of the composite.
