The organizing committee has the pleasure to invite you to the tenth edition of the International Conference on Durability of Composite Systems (Duracosys-2012, September 17-19, 2012). This series of conferences was initiated back in 1990 by G. Verchery and Albert Cardon (Belgium) and since then organized on a regular basis somewhere else in the world. Today, the department of Mechanics of Materials and Constructions (MeMC) is honored to be able to host this special tenth edition of the conference again in Brussels, capital of Europe. In view of the ever increasing use of composites it has become extremely important to better understand its long-term behavior under complex loading conditions including the influence and interaction of environmental variations. The aim of the conference is to bring together researchers both from academia and industry for exchanging new ideas, latest achievements and for promoting new collaborations. Besides special sessions organized by leading experts the conference program will include plenary and keynote lectures, technical papers and poster sessions. The list of special sessions will be made available on the web site. Suggestions for other topics are welcome and can be forwarded to the organizers. Together with all the members of the different committees we are looking forward to meet you in Brussels for an exciting Duracosys-2012.
