1 CONTEXT 1.1 About COST Founded in 1971, COST is one of the longest-running European instruments supporting cooper- ation among scientists and researchers across Europe. COST is an intergovernmental framework for European Cooperation in Science and Technology (COST), allowing the coordination of na- tionally-funded research on a European level.

However, in spite of Europe’s pole position in research and new developments in this field, structural glass is not yet incorporated in engineering and architectural engineering academic education. Knowledge transfer is required on different levels, educational and professional. One of the key targets of COST Action TU0905 “Structural Glass – Novel design methods and next generation products” on an educational level, is to develop an Education Pack to help educate students and research- ers in this field. These aims are channelled through activities within four working groups: COST Action TU0905, Mid-term Conference on Structural Glass – Belis, Louter & Mocibob (Eds) © 2013 Taylor & Francis Group, London, ISBN 978-1-138-00044-5 Characterization of interlayer properties – TG06 Status Report Dr G. F. Savineau Laminated glass expert (France) C. Butchart University of Cambridge (United Kingdom) D. Delincé Ghent University (Belgium) R. Speelman Eastman (Belgium) ABSTRACT: The material characterization and material improvement of glass elements by lamination with different interlayer materials are within the focus of COST TU0905/WG2/TG06. The Task Group “TG06 Interlayer properties” comprises 10 members from academia and industry. The main objectives, state-of-work, issues and concerns, next steps, perspectives & development within TG06 are presented in this paper. TG06 members are working on the 4 following goals: 1) to create a shared list of references (scientific, academic works, conference papers); 2) to collect, discuss and develop experimental and numerical meth- ods allowing characterization and modelling of the mechanical behaviour of viscoelastic inter- layers for the unfractured (SLS) and fractured (ULS) states of laminated glass; 3) to contribute to European Standards (CEN TC129/WG08 - Mechanical Strength) and Eurocodes (CEN TC250/WG3-Structural Glass) works; and 4) to contribute to the Educational Pack and COST Training School.
