It is a pleasure to write the foreword to this book. This work emphasizes for the first tone in one volume how interfaces in fibrous composites can be defined, measured, improved and optimized. Many practitioners of composites technology will find in this book the information they have been seeking to match fiber and matrix at the interface thereby obtaining the best mix of properties in the final application. Composites engineering is a relatively young field in which the test methods and measurement techniques are not yet fully developed. Even more important, the ideas _ le properties of composites to the interface structure are still emerging. This book not only reviews the historic and pragmatic methods for studying composites; but it also presents the most recent theories and fundamental tests of interface properties. This allows the reader to find the true framework of theory to fit his/her observations. The fact that two brittle materials can be brought together to give a tough product ;s the proof that interfaces are critical to composite properties. However, the complexities of this process depend on the raw materials, on the surface chemistry of mponents, on the fabrication procedures, on the chemistry of hardening, and on the damage and corrosion sustained in use. A wide view of material science, chemistry, mechanics, process engineering and applications experience is necessary to focus successfully on the role of the interface. The authors have demonstrated Such a global view in this volume.I have known Professor Mai for over 20 years. He is a foremost authority on fracture mechanics of composite materials, having studied polymer composites, ent, ceramic and cement, ceramic and natural composite systems, in the US, Britain, Australia and Hong Kong. In particular, he has made memorable contributions to the understanding of cracks and to the crack-inhibiting effects seen in fibrous composites. He has previously coauthored two books on fracture. Professor Kim originally worked in the composites industry and has returned during the past 10 years to study interface mechanisms more closely. He is currently working in the Hong Kong University of Science & Technology. In summary, the topic of engineered interfaces in composites is an important one, critical to the advance of the composites industry. Many practitioners from a range of disciplines are seeking the information which can be found in this book. The authors display the wide experience and theoretical knowledge necessary to provide a critical view of the subject. I strongly recommend this volume to the composite : pert and student alike.
