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

庞巴迪是第一家在北美制造业中引入弹性连接作为主要连接技术的公司，因为这种创新技术带来了整体经济效益和技术优势。然而，粘接接头的耐久性是客户经常询问的关键问题，目前答案未知。粘合剂材料受到紫外线辐射、温度波动、潮湿清洁化学品和其他环境因素的严重影响。粘合剂的性能会降低，导致粘合强度的快速和过早劣化。这是一个重大的技术限制和不确定性。庞巴迪迫切需要进行加速老化评估，以证明粘合剂的长期耐久性，以便完全适应
