Bonded Joints and Repairs to Composite Airframe Structures is a single-source reference on the state-of-the-art in this rapidly growing area. It provides a thorough analysis of both internal and external joints and repairs, as well as discussions on damage tolerance, non-destructive inspection, self-healing repairs, and other essential information not only on the joints and repairs themselves, but critically, on how they differ from bonds and repairs to metallic aircraft. Authors Wang and Duong bring a valuable combination of academic research and industry expertise to the book, drawing on their cutting-edge composite technology experience, including analytic and computational leadership of damage and repair planning for the Boeing 787. Intended for graduate students, engineers, and scientists working on the subject in aerospace industry, government agencies, research labs, and academia, the book is an important addition to the limited literature in the field. - Offers rare coverage of composite joints and repairs to composite structures, focusing on the state of the art in analysis - Combines the academic, government, and industry expertise of the authors, providing research findings in the context of current and future applications - Covers internal and external joints and repairs, as well as damage tolerance, non-destructive inspection, and self-healing repairs - Ideal for graduate students, engineers, and scientists working in the aerospace industry, government agencies, research labs, and academia

This book is based on lectures held at the faculty of mechanical engineering at the Technical University of Kaiserslautern. The focus is on the central theme of societies overall aircraft requirements to specific material requirements and highlights the most important advantages and challenges of carbon fiber reinforced plastics (CFRP) compared to conventional materials. As it is fundamental to decide on the right material at the right place early on the main activities and milestones of the development and certification process and the systematic of defining clear requirements are discussed. The process of material qualification - verifying material requirements is explained in detail. All state-of-the-art composite manufacturing technologies are described, including changes and complemented by examples, and their improvement potential for future applications is discussed. Tangible case studies of high lift and wing structures emphasize the specific advantages and challenges of composite technology. Finally, latest R&D results are discussed, providing possible future solutions for key challenges such as low cost high performance materials, electrical function integration and morphing structures.

Design and Analysis of Composite Structures enables graduate students and engineers to generate meaningful and robust designs of complex composite structures. Combining analysis and design methods for structural components, the book begins with simple topics such as skins and stiffeners and progresses through to entire components of fuselages and wings. Starting with basic mathematical derivation followed by simplifications used in real-world design, Design and Analysis of Composite Structures presents the level of accuracy and range of applicability of each method. Examples taken from actual applications are worked out in detail to show how the concepts are applied, solving the same design problem with different methods based on different drivers (e.g. cost or weight) to show how the final configuration changes as the requirements and approach change. Provides a toolkit of analysis and design methods to most situations encountered in practice, as well as analytical frameworks and the means to solving them for tackling less frequent problems. Presents solutions applicable to optimization schemes without having to run finite element models at each iteration, speeding up the design process and allowing examination of several more alternatives than traditional approaches. Includes guidelines showing how decisions based on manufacturing considerations affect weight and how weight optimization may adversely affect the cost. Accompanied by a website at www.wiley.com/go/kassapoglou hosting lecture slides and solutions to the exercises for instructors.
