Vogelesang Sponsors 211 viii Preface During September 24-26, 2001, the Faculty of Aerospace Engineering of the Delft University of Technology in the Netherlands organised the Glare - the New Material for Aircraft Conference, an international conference on the relationship between design, material choice and application of aircraft materials with respect to new developments in industry. Eminent representatives from the aircraft manufacturing world, including manufacturers, airlines, airports, universities, governments and aviationauthorities, werepresentatthisconference to meetandexchange ideas- see the group photo on the next two pages. The fact that the conference was heldjust two weeks after ‘September 11, 2001’ put things in a rather unique perspective. The aim of the conference was to illustrate the many unique applications of the Glare family of fibre metal laminates and to provide for the exchange and distribution of information regarding this material in order to stimulate their acceptance and promote further application. The introduction of fibre metal laminates into the commercial aviation market took about 20 years’ time. Introducing new technologies should not be taken lightly, however; the aircraft industry is by naturerather conservative and innovations must therefore be proven – a paradox actually – in all possible ways before they can be introduced inreal aircraftstructures. Notonlydo technical aspectsplay arole in this respect; historical, cultural, economical and political issues are equally important. So, besides the technical aspects of Glare, which were discussed in the afternoon sessions of the conference and which are published in a first book with the title Fibre MetalLaminates - an introduction, the less technical and non-technical issues related to Glare’s introduction in aviation were also discussed from different perspectives. These discussions form the contents ofthis book. The conference also served as a platform and backdrop to the honouring of Professor BoudVogelesang, who had longbeen an enthusiastic driving force behind the development of Glare, as an emeritus of the Chair Aerospace Materials. For this reason,hisEmeritus Lecture isalsoincludedinthisbook. A third book with the title Glare - history ofthe development ofa new aircraft material, which provides the inside story of the development activities in the Structures and Materials Laboratory ofthe Faculty ofAerospace Engineering ofthe DelftUniversityofTechnology, isalso available. Like the previous two books, this book is published by Kluwer academic publishers b.v. ThankstoArno Schouwenburgoncemore fortransformingourdigital copy into abeautifuladditiontoone's library. ix x xi
