Evaluation of VIPs After Mild Artificial Aging During 10 years:Focus on the Core Behavior

摘要：

　　The prediction of the long term performance of VIPs remains challenging.To improve the forecast,the evaluation of VIPs aged for very long periods can help significantly.This study reports the characterization method which was implemented on VIPs after an artificial aging of 10 years in the laboratory,at room temperature and in two different relative humidities (quite low and high).The aim is to evaluate the hygrothermal and structural evolutions of the core material and to interpret them thanks to the detailed study of the aging of the fumed silica core.The permeance of the barrier laminate is also estimated.
