The results of an assessment of the state-of-the-art in the design and manufacturing of large composite structures are described. The focus of the assessment is on the use of polymeric matrix composite materials for large airframe structural components, such as those in commercial and military aircraft and space transportation vehicles. Applications of composite materials for large commercial transport aircraft, general aviation aircraft, rotorcraft, military aircraft, and unmanned rocket launch vehicles are reviewed. The results of the assessment of the state-of-the-art include a summary of lessons learned, examples of current practice, and an assessment of advanced technologies under development.

Summary: A Generalized Multiscale Analysis Approach brings together comprehensive background information on the multiscale nature of the composite, constituent material behaviour, damage models and key techniques for multiscale modelling, as well as presenting the findings and methods, developed over a lifetime's research, of three leading experts in the field. The unified approach presented in the book for conducting multiscale analysis and design of conventional and smart composite materials is also applicable for structures with complete linear and nonlinear material behavior, with numerous applications provided to illustrate use. Modeling composite behaviour is a key challenge in research and industry; when done efficiently and reliably it can save money, decrease time to market with new innovations and prevent component failure.
Long-Term Durability of Polymeric Matrix Composites presents a comprehensive knowledge-set of matrix, fiber and interphase behavior under long-term aging conditions, theoretical modeling and experimental methods. This book covers long-term constituent behavior, predictive methodologies, experimental validation and design practice. Readers will also find a discussion of various applications, including aging air craft structures, aging civil infrastructure, in addition to engines and high temperature applications.
Practical Micromechanics of Composite Materials provides an accessible treatment of micromechanical theories for the analysis and design of multi-phased composites. Written with both students and practitioners in mind and coupled with a fully functional MATLAB code to enable the solution of technologically relevant micromechanics problems, the book features an array of illustrative example problems and exercises highlighting key concepts and integrating the MATLAB code. The MATLAB scripts and functions empower readers to enhance and create new functionality tailored to their needs, and the book and code highly complement one another. The book presents classical lamination theory and then proceeds to describe how to obtain effective anisotropic properties of a unidirectional composite (ply) via micromechanics and multiscale analysis. Calculation of local fields via mechanical and thermal strain concentration tensors is presented in a unified way across several micromechanics theories. The importance of these local fields is demonstrated through the determination of consistent Margins of Safety (MoS) and failure envelopes for thermal and mechanical loading. Finally, micromechanics-based multiscale progressive damage is discussed and implemented in the accompanying MATLAB code. Emphasizes appropriate application of micromechanics theories to composite behavior Addresses multiple popular micromechanics theories, which are provided in MATLAB Discusses stresses and strains resulting from realistic thermal and mechanical loading Includes availability of solution manual for professors using the book in the classroom
Foreign Object Debris and Damage in Aviation discusses both biological and non-biological Foreign Object Debris (FOD) and associated Foreign Object Damage (FOD) in aviation. The book provides a comprehensive treatment of the wide spectrum of FOD with numerous cost, management, and wildlife considerations. Management control for the debris begins at the aircraft design phase, and the book includes numerical analyses for estimating damage caused by strikes. The book explores aircraft operation in adverse weather conditions and inanimate FOD management programs for airports, airlines, airframe, and engine manufacturers. It focuses on the sources of FOD, the categories of damage caused by FOD, and both the direct and indirect costs caused by FOD. In addition, the book provides management plans for wildlife, including positive and passive methods. The book will interest aviation industry personnel, aircraft transport and ground operators, aircraft pilots, and aerospace or aviation engineers. Readers will learn to manage FOD to guarantee air traffic safety with minimum costs to airlines and airports.
The combination of conductive polymer technology with the ability to produce nanofibres will facilitate major new developments in biotechnology and information technology, benefiting such areas as scaffolds for tissue engineering and drug delivery systems; wires, capacitors, transistors and diodes; sensor technology; biohazard protection; and energy transport, conversion and storage. The work on nanofibrous materials presented here is designed, first of all, to instruct scientists in the most advanced methods for the formation of nanofibres and nanotubes. The second section covers the physics and chemistry of nanofibres, while the third deals with computer simulation and modelling. The applications described in section 4 include biomedical applications, nanotube-based devices, electronic applications of nanotubes and nanofibres, nanofluidics, and composites. Finally, the fifth section discusses recent developments in nanomaterials, nanoparticles and nanostructures.
