Reliability Climatic Test for Composite based on Probabilistic Arrhenius model

David DELAUX, Thomas ILLING, Abdelkhalak EL HAMI

Abstract

This paper proposes a methodology to verify composite products reliability through its life time using a probabilistic Arrhenius model. It will present the challenge that automotive industry faces and study the potential improvement to be considered in order to improve the reliability during the design and validation phases. The formulas developed in this research permit to set up an accelerated test at the strict necessary needs. The goal is the integration of the variability from Energy of activation (Ea), Test Conditions (Test Bench Temperature Tb) and a dispersion from usage temperatures (Tu)
