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.

The ingenuity and visibility of NASA space programs, such as the max launch abort system (MLAs), are sparking the creativity, knowledge transfer, and unique applications of revolutionary technologies in areas such as aerospace, wind energy, transportation, oil, safety, and civil infrastructure. Lightweight, high-strength, carbon-fiber composites materials, vacuum-assisted resin transfer molding, smart sensors, out-of-autoclave curing of autoclave composites, unified structures, structural health monitoring systems, smart phone/RFID tracking, determinant assembly, forensic engineering, and the digital tapestry that ties everything together are just a few of the technological advances perfected in NASA’s programs. Successful composites technology transfer takes the discussion of these technologies to the next level — addressing the advantages and challenges to their more widespread industrial application. Readers will get insight into how high-strength, carbon-fiber composites and its related technologies are making inroads into products such as commercial airplane seats and carts, turbine blades, firefighting equipment, trucks, buses, lifting and support devices, and containers. The author shares breakthrough thinking on other potential applications, such as a new lighter than air ship, prototype vehicles, driver health and safety, firefighter safety, and bridge infrastructure safety and health monitoring. According to Foreword author, Tim Shinbara, vice president of manufacturing technology at AMT (Association for Manufacturing Technology), “...it is of considerable value to search out, discover, and digest resources such as this book in an effort to continually improve the lens by which we innovate.” Aside from new product innovations, extension of the manufacturing technologies, and processes described herein have the potential to not only add new functionality or modify the existing functionality of existing products and systems, but in many cases, adoption would require minimal effort from the manufacturing enterprise.

The availability of efficient and cost-effective technologies to repair or extend the life of aging military airframes is becoming a critical requirement in most countries around the world, as new aircraft becoming prohibitively expensive and defence budgets shrink. To a lesser extent a similar situation is arising with civil aircraft, with falling revenues and the high cost of replacement aircraft. This book looks at repair/reinforcement technology, which is based on the use of adhesively bonded fibre composite patches or doublers and can provide cost-effective life extension in many situations. From the scientific and engineering viewpoint, whilst simple in concept, this technology can be quite challenging particularly when used to repair primary structure. This is due to it being based on interrelated inputs from the fields of aircraft design, solid mechanics, fibre composites, structural adhesive bonding, fracture mechanics and metal fatigue. The technologies of non-destructive inspection (NDI) and, more recently smart materials, are also included. Operational issues are equally critical, including airworthiness certification, application technology (including health and safety issues), and training. Including contributions from leading experts in Canada, UK, USA and Australia, this book discusses most of these issues and the latest developments. Most importantly, it contains real histories of application of this technology to both military and civil aircraft.

The major objective of this book was to identify issues related to the introduction of new materials and the effects that advanced materials will have on the durability and technical risk of future civil aircraft throughout their service life. The committee investigated the new materials and structural concepts that are likely to be incorporated into next generation commercial aircraft and the factors influencing application decisions. Based on these predictions, the committee attempted to identify the design, characterization, monitoring, and maintenance issues that are critical for the introduction of advanced materials and structural concepts into future aircraft.
