Assessment of ageing and long-term durability of adhesive materials

庞巴迪是第一家将弹性粘接作为北美制造业主要连接技术的公司，这是因为这项创新技术带来的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提出的关键问题，目前答案尚不清楚。粘合剂材料受到紫外线辐射、温度波动、湿气清洗剂和其他环境因素组合的严重影响。粘合剂的性能可能会退化，导致粘接强度的快速和过早劣化。这构成了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，以便充分适应

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
