Product DurabilityIn the manufacturing industry, demands on functionality, user reliability, and technical durability of materials and products are steadily increasing. Importantly, such demands need to be combined with cost-effectiveness, minimised environmental impact, and shorter lead times.
New and improved methods for life-cycle assessment, e. g. real-time measurements or more sensitive methods for the study of early stages of material degradation, are required to fulfil these demands.
Our research in life-cycle technology is focused on developing and applying various methods that facilitate a systematic approach to material choice and to evaluation of long-term reliability and ecological properties of materials and components in the context of product development.
Important aspects of this work are the identification, characterisation and analysis of the various lifetime-limiting mechanisms or failure modes of the studied materials and components. Studied materials and components include polymeric construction materials, electrical components, advanced optical coatings for construction applications (anti-reflectant layers, chromogenous glass coatings, reflectors, sunlight-absorbent façade materials) protective coatings for vehicles, corrosion resistant materials for chimneys, paints used in building preservation, joint sealing compounds, and materials for information storage.
Examples of ongoing projects:
- The EU project PERFORMANCE: A science base on PV performance for increased market transparency and customer confidence. The project entails pre-normative research in the field of photo voltaic (PV) cells (i.e. solar cells) aimed at developing reliable testing methods for PV modules and complete PV systems, including systems integrated into buildings. The research focuses on various PV-technologies, including thin film PV and PV modules based on crystalline silicon. Another very important research area is encapsulation materials.
- A comparison of single and double sided writing on paper (Swedish National Archives). The objective here is to investigate whether or not the binding of double-sided documents causes the information to become difficult to access or illegible when archived.
- An investigation into the aging resistance in writing (Swedish National Archives). Writing on paper with various surface properties, filler content, etc. is investigated with regards to resistance to deterioration.
- EASYCLEAN. A project on easily-cleaned surfaces, focusing on vehicle paints. The main objective is to evaluate surface washability.
- Durability of packing and labelling materials used for redeposition of archaeological finds. A collaboration with Stiftelsen Västsvensk Konservatorsateljé (the Conservation Foundation of Western Sweden).
- The VCI project, aiming at further development of packaging materials impregnated with vapour phase inhibitors for the transport and storage of metals.
- The electronics project, aiming at further development of a method for accelerated corrosion-testing of electronic products.
- The replacement of galvanic surface treatments.
- Resistance to chemicals in joint sealant compounds used on roads and airfields.
