Activity report of COST Action TU0905 working group 2: material characterization and material improvement

This paper provides an overview of the members and activities of Working Group (WG) 2 of the COST Action TU0905 Structural Glass - Novel design methods and next generation products. Within the main theme "Material Characterization and Material Improvement" the working group was subdivided into three task groups (TG): "Thermal Tempering", "Glass Strength and Ageing of Glass" and "Interlayer Properties". Working group 2 has actively contributed to the meetings and various events within the COST Action, such as the Training School and COST action conferences. Several Short Term Scientific Missions (STSM) have been undertaken by members of WG 2, which resulted in joint publications. Due toe the network, new research collaborations have been initiated by members of WG 2, which already led to successful joint research applications.
