Info autore
Dr. Wallenberger completed his undergraduate studies in Chemistry at the University in Graz, Austria (1954) and pursued graduate research at Fordham University in New York, where he received his M.S. degree (1956) in pilot process research and his Ph.D. in Organic Chemistry (1958) in the chemistry of polycyclic aromatic carbon precursors. He was an Instructor in Chemistry at Fordham (1957-58) and a Research Fellow at Harvard (1958-59). He joined Du Pont Fibers, Pioneering Research Laboratory, in 1959, where he studied, for more than three decades, the relationships between structures, properties and value-in-use of new materials, and contributed to the commercialization of new fibers, polymers and composites through intrapreneurial research, project management and technology transfer. Dr. Wallenberger retired from DuPont in 1992, became a Research Professor (Materials Science) at the University of Illinois in Urbana-Champaign in 1992, a Visiting Professor (Textiles) at the University of California in Davis in 1994. He joined PPG in Pittsburgh as Staff Scientist in 1995.§Among many professional honors, Dr. Wallenberger received the Environmental Respect Award from Du Pont. He is a Fellow of the American Ceramic Society, and a member of the American Chemical Society, the Material Research Society, and the Association of Harvard Chemists.
Riassunto
Deals with plant and animal derived natural fibers, natural composite matrix materials and biocomposites. This book reviews the sources, structures, properties and applications of the materials. It aims to support research, assist scientists and designers in industry, and facilitate materials science instruction in universities and colleges.
