FINAL PROGRAM

SECOND INTERNATIONAL SYMPOSIUM ON ADHESIVE JOINTS: FORMATION, CHARACTERISTICS AND TESTING

MAY 22-24, 2000

ROBERT TREAT HOTEL

NEWARK, NJ

This symposium is the follow on to the first gathering on this topic held as a part of the American Chemical Society meeting in Kansas City, 1982. There are a myriad of applications (ranging from aerospace to surgery) where adhesives are used to join different materials. Therefore, the understanding of the behavior of adhesive Joints becomes very important. There are many factors which can influence the behavior of adhesive joints, e.g., interfacial aspects, joint design, mode of stress, etc., and in order to understand the joint behavior in a holistic manner, one must take due cognizance of all these relevant factors. In conformity with the title of the Symposium, it is planned to address not only how to make acceptable joints but their characterization, durability, and testing will be accorded due consideration. In light of this, the primary focus of this symposium will be to provide a forum for reviewing old results, as well as, to present an update on the latest developments in adhesive joint technology.
