Bombardier is the first company to introduce Elastic Bonding as a major joining technique in manufacturing in North America due to the overall economic benefits and technical advantages that are associated with this innovative technique. However, the durability of the bonded joint is a key question frequently asked by customers, and the answer is currently unknown. Adhesive materials are severely affected by UV-radiations, temperature fluctuations, moisture cleaning chemicals and a combination of other environmental factors. The properties of the adhesive can be degraded, leading to the fast and premature deterioration of the bonding strength. This constitutes a major technical limitation and uncertainty. Bombardier has a pressing need to conduct accelerated ageing assessment to prove the bond long term durability, in order to fully adapt the
