Due to the increasing interest in lightweight structures, carbon-fiber reinforced plastics are increasingly applied, especially in the transportation industry. An interesting technology for joining these materials is adhesive bonding due to numerous advantages compared to conventional techniques like riveting. However, to achieve a strong and durable bond, surface pre-treatment is necessary to remove residues of release agents that are transferred to the surface during manufacturing. This paper describes analytical experiments, namely SEM and XPS, performed on CFRP surfaces pre-treated with 308 nm excimer laser radiation.

Femtosecond lasers bring numerous process‐enabling advantages to precision microprocessing applications. However, taking a new, ultrafast laser‐based application from a first demonstration to full‐blown manufacturing at market‐enabling throughput rates is usually more difficult than for longer pulsewidth lasers. This is because processes utilizing nanosecond (and longer) pulsewidth lasers can rely on a massive knowledge base, built up by laser manufacturers, systems builders and end users, over decades of application. In contrast, femtosecond laser processing is very much in its infancy, with a limited body of proven applications (or even research and development) to draw on. In this article, we describe how a process window was defined, improved, and finalized in the specific case of precision cutting of thin glass panels for display applications.
