Available in PDF, EPUB and Kindle. Book excerpt: The conventional approach to through-life-support for aircraft structures can be divided into the following phases: (i) detection of defects, (ii) diagnosis of their nature and significance, (iii) forecasting future behaviour-prognosis, and (iv) pre scription and implementation of remedial measures including repairs. Considerable scientific effort has been devoted to developing the science and technology base for the first three phases. Of particular note is the development of fracture mechanics as a major analytical tool for metals, for predicting residual strength in the presence of cracks ( damage tolerance) and rate of crack propagation under service loading. Intensive effort is currently being devoted to developing similar approaches for fibre composite structures, particularly to assess damage tolerance and durability in the presence of delamination damage. Until recently there has been no major attempt to develop a science and tech nology base for the last phase, particularly with respect to the development of repairs. Approaches are required which will allow assessment of the type and magnitude of defects amenable to repair and the influence of the repair on the stress intensity factor (or some related parameter). Approaches are also required for the development and design of optimum repairs and for assessment of their durability.

This book was released on 2003-01-23 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: Bonded composite repairs are efficient and cost effective means of repairing cracks and corrosion grind-out cavity in metallic structures, and composite structures sustained impact and ballistic damages, especially in aircraft structures. This book grew out of the recent research conducted at the Boeing Company and the Defence Science and Technology Organisation (DSTO, Australia) over the past ten years. Consequently it is predominately a compilation of the work by the authors and their colleagues at these two organizations on the design and analysis of composite repairs. Composite Repair is entirely devoted to the design and analysis of bonded repairs, focusing on the mathematical techniques and analysis approaches that are critical to the successful implementation of bonded repairs. The topics addressed are presentated in a sufficiently self-explanatory manner, and serve as a state-of-the-art reference guide to engineers, scientists, researchers and practitioners interested in the underpinning design methodology and the modelling of composite repairs. The only book devoted entirely to the design and analysis of bonded repairs Focusing on mathematical techniques and analytical methodologies that are critical to the successful implementation of bonded repair A companion reference book to the United Stated Air Force (USAF) bonded repair guidelines (Guidelines for Composite Repair of Metallic Structures-CRMS, AFRL-WP-TR-1998-4113) and the Royal Australian Air Force (RAAF) Design Standard DEF(AUST)995 Covering a variety of topics and effects: repairs of fatigue and sonic fatigue cracks, and corrosion grind-out cavity, and effects of secondary bending, octagon-shaped patches, thermal residual stresses, patches in proximity, patch tapering edge, etc.

This book was released on 2021 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book presents established methods of structural health monitoring (SHM) and discusses their technological merit in the current aerospace environment. While the aerospace industry aims for weight reduction to improve fuel efficiency, reduce environmental impact, and to decrease maintenance time and operating costs, aircraft structures are often designed and built heavier than required in order to accommodate unpredictable failure. A way to overcome this approach is the use of SHM systems to detect the presence of defects. This book covers all major contemporary aerospace-relevant SHM methods, from the basics of each method to the various defect types that SHM is required to detect to discussion of signal processing developments alongside considerations of aerospace safety requirements. It will be of interest to professionals in industry and academic researchers alike, as well as engineering students. This article/publication is based upon work from COST Action CA18203 (ODIN - http://odin-cost.com/), supported by COST (European Cooperation in Science and Technology). COST (European Cooperation in Science and Technology) is a funding agency for research and innovation networks.

This book was released on 2018 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bonded repair is one of the structural repair technologies that the aircraft industry uses to restore the strength of fuselage structures and increase the life of an aircraft. Bonded repairs are superior to the conventional metallic fastened repairs in that the former yield a higher stiffness and lower stress concentrations and are more aerodynamically and structurally efficient. Bonded repair technology has been used to repair military aircraft for over three decades but has not been certified for repairing commercial aircraft due to the lack of sufficient performance data to support their airworthiness. Experimental work and analytical modeling of bonded repairs have also been limited to those of flat coupon specimen under ambient environmental conditions. In this study, experimental and analytical work on a full-scale curved fuselage panel with various bonded repairs is conducted to investigate their durability and integrity. The experimental work was carried out using the Federal Aviation Administration's Full-Scale Aircraft Structural Test Evaluation and Research fixture. The objectives are to characterize the durability and fatigue performance of boron/epoxy (B/Ep) and aluminum bonded repairs under a simulated service load condition over the design service life of the airplane and to investigate tools for evaluating and monitoring the repair integrity over the life of the part. During all test phases, damage formation and growth of cracks and disbonds were monitored and recorded using a structural health monitoring system and several nondestructive inspection methods. In addition, strains in the vicinity of the repair patches were continuously recording using strain gages and the digital image correlation method. Experimental results indicated that the bonded repairs are effective to reduce the fatigue crack growth rate. A linear elastic fracture mechanics based analytical model is developed to predict the growth rates of fatigue cracks in the curved panel repaired by bonded patches. The unique feature of this model is that, by using a fuselage-dependent geometric correction factor and incorporating the bonded repair theory, this model can be applied to predict the growth of a crack under any type of bonded repair in a given fuselage. The model has been validated by comparing the predicted crack growth rate results with that obtained experimentally.

Available in PDF, EPUB and Kindle. Book excerpt: • One of very few books available to cover this subject area. • A practical book with a wealth of detail. This book covers the major manufacturing processes for polymer matrix composites with an emphasis on continuous fibre-reinforced composites. It covers the major fabrication processes in detail. Very few books cover the details of fabrication and assembly processes for composites. This book is intended for the engineer who wants to learn more about composite processing: any one with some experience in composites should be able to read it. The author, who has 34 years experience in the aerospace industry, has intentionally left out mathematical models for processes so the book will be readable by the general engineer. It differs from other books on composites manufacturing in focussing almost solely on manufacturing processes, while not attempting to cover materials, test methods, mechanical properties and other areas of composites.
