How long have composites been around? Where does the classical laminate theory come from? Who made the first modern fiber composite? This work in the history of materials science is the first examination of the strategies employed in the nineteenth and twentieth centuries in researching and developing hybrid materials. The author analyzes numerous sources which record a regular back and forth between applied design and exploratory materials engineering in building such "modular materials". The motivations, ideas, and concepts of engineers, scientists, and other players in industry and research are also examined within the context of their day. This book presents the development and importance of composite materials within historical context. The content includes Early composite materials The development of composite materials in the industrial nineteenth century Composites in twentieth-century polymer chemistry The development of hybrid material systems in the second half of the twentieth century Summary. The author: Dr. Andreas T. Haka is an engineer and historian of science and technology. He is currently a lecturer in the Section for the History of Science and Technology at the University of Stuttgart.
