Investigation of the effect of surface roughness on adhesive bonding of laser textured aluminium alloys

Laserax是一家总部位于魁北克L的公司，致力于实施自动化激光打标和清洁解决方案，为制造企业提供交钥匙机器和OEM系统。Laserax不断发展壮大，不断突破激光技术的极限，通过持续的研发活动在行业内建立新的标准。由于轻量化在运输行业一直是一个挑战，该公司表现出了极大的兴趣，通过使用他们的激光系统对铝表面进行纹理处理以进行结构粘接，从而减少了组装过程中使用的螺栓和铆钉的数量。本项目旨在研究激光毛化铝表面粗糙度对其表面性能的影响及其对接头强度的影响，最终为毛化工艺的优化做出贡献，以提高粘接接头的性能。

Laserax, a Québec based company located in Lévis, Québec, strives in implementing automated laser marking and cleaning solutions, providing turnkey machines and OEM systems for manufacturing companies. Laserax constantly thrives to push the limits of laser technology and establish new standards in the industry via continued research and development activities. Light weighting in transport industry being a constant challenge, the company has demonstrated tremendous interest in contributing to reducing weight by using their laser systems to texture aluminum surfaces for structural adhesive joining, a technique leading to use of reduced number of bolts and rivets in assembling. This project aims at studying the effect of surface roughness of laser textured aluminum surfaces on their surface properties and how it affects joint strengths, ultimately contributing to the optimization process of the texturing process toward improved performance of bonded joints.
