Abstract

The expected increasing duration of service life of polymeric materials requires suitable test and extrapolation methods for an assessment of the aging effects under various loads and exposures. Taking data from polymeric waterpoofing membranes after aging in water at elevated temperatures as an example, the applicability of the time-temperature superposition (TTS) principle for extrapolation is investigated. Some problems and limitation are highlighted.

Résumé

L'accroissement attendu de la durée de vie des matériaux polymères nécessite des méthodes d'extrapolation adéquates pour prendre en compte les effets du vieillissement sous diverses sollicitations et expositions. En prenant comme exemple des données expérimentales obtenues pour le vieillissement en eau chaude de membranes d'étanchéité polymériques, l'applicabilité du principe TTS pour l'extralation est investiguée. Quelques limitations et problèmes sont discutés.
