Developments in the Science and Technology of Composite Materials

Dr A.R. BUNSELL President de l'Association Europeenne des Materiaux Composites Apres Ie succes des deux precedentes editions, Ie troisieme Congres Europeen sur les Materiaux Composites, ECCM-3, s'annonce de tres haut niveau. La premiere reunion s'est tenue a BORDEAUX en septembre1985 tandis que la seconde, jumelee avec Ie sixieme Congres International sur les Materiaux Composites, ICCM-6 eut lieu a LONDRES en juillet 1987. Ces deux reunions ont clairement montre I'importance de la recherche sur les materiaux composites en Europe. Elles ont pu rassembler les chercheurs venus de toute l'Europe et du monde entier. Ce troisieme congres nous ramene a BORDEAUX et souligne I'interet porte aux materiaux composites a BORDEAUX et en Aquitaine, haut lieu d'application des technologies de pointe. La creation a BORDEAUX de l'Association Europeenne des Materiaux Composites, A.E.M.C., a ete Ie fait a la fois d'une volonte politique et d'une prise de conscience locales ainsi que de la presence d'un tissu industriel favorable au developpement de celie activite. Le travail assidu du comite scientifique, compose de specialistes europeens, grace a qui les sujets traites et les articles sont varies et de haut niveau, nous assure de la qualite du compte rendu de ECCM-3 qui comptera desormais parmi les ouvrages de reference. Plus notable encore, est Ie fait que ECCM-3 contribue a la construction d'une grande communaute internationale des composites, composee de chercheurs venus du monde entier.
