FINAL PROGRAM



INTERNATIONAL SYMPOSIUM ON INTERFACES IN POLYMER COMPOSITES

November 30 - December 1, 2000

ROBERT TREAT HOTEL, NEWARK, NJ

Composites are more and more becoming the materials of choice for a wide range of applications in the modern economy. Everything from sporting equipment to high performance aircraft are being fabricated from composites since only these materials can meet all the desired performance requirements. However, it is well known that the performance of any given composite is critically dependent on the adhesion of the matrix to the reinforcing filler(particle, fabric or fiber). The preparation and characterization of the matrix/filler interface is one of the most challenging and critical tasks in the fabrication of any composite material. The purpose of this symposium is to provide a forum for discussion of various ramifications of the myriad composite materials currently available and the understanding of the matrix/filler interfaces which make these structures possible. Primary focus will be on the dissemination of the latest information available and the cross-pollination of ideas. Additionally, this symposium is organized to serve as a venue for the mutual and fruitful interaction among participants for the furthering of scientific, professional and practical interests.
