Dry pretreatment 2

Dry pretreatment 2

Pretreatment is important to ensure good adhesive bonding. The goal of this project is to study how dry pretreatment with plasma and laser can provide improved quality assured bonding of metals and composites and a contribute to a deeper understanding of the interaction between the surface and adhesive.

Pretreatment processes for adhesive bonding

Dry pretreatment facilitates surface near, local, rapid, robust, automated and sustainable surface treatment before bonding. This project are evaluating and further developing dry pretreatment processes, primarily based on atmospheric plasma jet (APPJ) and ND:YAG laser in order to bond metals and composite materials in a repeatable and quality assured manner.

Project goal

The aim of the project is to achieve a deeper understanding of the chemical and structural interaction between adhesive and surface, and to compare quality assurance methods for characterizing the effects of dry pretreatment.

The methods are expected to be used in both small-scale and mass production. The results will be evaluated through laboratory experiments, demonstrators and implementation and sustainability studies. Results will be disseminated through publications in technical journals, presentation at conferences and implemented in courses.
