Damage and Repair of Aerospace Composite Materials reports the latest developments on the detection and repair of composite structures from the perspective of ten SAE technical papers, especially chosen for this book. This micro-collection of papers offers an overview of composite utilization on large-scale commercial aircraft as well as an outline of general damage inspection and repair of composite structures. On the damage detection side, really important techniques are explained, including: • Porosity inspection of large composite panels. • Damage detection of large composites using acoustic ultrasonic and radio frequency methods. • Discrimination of damaged and undamaged composite panels using acoustic emission sensors. • Automated defect inspection system integrated in the production line by utilizing laser sensors and cameras. The latest studies in damage repair of composite structures are also presented, including: • the design of a bonded repair technique for multilayer laminate composite panels. • the analysis on the performance of bolted repair vs. bonded repair. • the method for economically repairing the holes on composites. • the development of a novel cutting tool for the scarf repair of composites. • the use the 3D-printing technology to repair gaps and steps in large composite panels

This book focuses on the repair of polymer composites for critical components in aerospace industries. It also covers the complexities of failure and repair of composites, types of fiber reinforcement and bonding. It includes special topics on damage assessment using on-site inspection (NDT and THz techniques) and automated repair processes for reliability and repeatability. Repair of Advanced Composites for Aerospace Applications also describes the characterization, modelling and simulation of the composites' damage mechanisms with respect to specific environments and applications. Failures associated with various composite repairing techniques for aerospace applications are also covered. Key Features: * Addresses the composites development process including damage detection and repair for aerospace applications. * Covers research on the multi-scale process modelling, material modelling, self-healing, repairing and their analyses. * Concentrates on the repair of composites for weight-sensitive applications in automobiles and aerospace. * Analyses perspectives on materials processing and material design. * Details composite joints, their failure, and operations of aircraft component in various environments. This book is aimed at researchers, professionals and graduate students in composite materials, manufacturing, aerospace engineering, advanced materials design and manufacturing, composite materials repair, and hybrid materials repair.

The advantages of composite materials include a high specific strength and stiffness, formability, and a comparative resistance to fatigue cracking and corrosion. However, not forsaking these advantages, composite materials are prone to a wide range of defects and damage that can significantly reduce the residual strength and stiffness of a structure or result in unfavorable load paths. Emphasizing defect identification and restitution, Defects and Damage in Composite Materials and Structures explains how defects and damage in composite materials and structures impact composite component performance. Providing ready access to an extensive, descriptive list of defects and damage types, this must-have reference: Examines defect criticality in composite structures Recommends repair actions to restore structural integrity Discusses failure modes and mechanisms of composites due to defects Reviews NDI processes for finding and identifying defects in composite materials Relating defect detection methods to defect type, the author merges his experience in the field of in-service activities for composite airframe maintenance and repair with indispensable reports and articles on defects and damage in advanced composite materials from the last 50 years.

The new edition of the well known Care and Repair of Advanced Composites, 3rd Edition, improves on the usefulness of this practical guide geared towards the aerospace industry. Keith B. Armstrong, the original lead author of the first edition was still in charge of this project, counting on the expert support of Eric Chesmar, senior composites specialist at United Airlines. Mr. Chesmar is also an active member of SAE International's CACRC (Commercial Aircraft Composite Repair Committee), an elite group of industry experts dedicated to the standardization, safety, security, and efficiency of composite repairs in the airline industry. Mr. Francois Museux (Airbus) and Mr. William F. Cole II also contributed. Care and Repair of Advanced Composites, 3rd Edition, presents a fully updated approach to the training syllabus recommended for repair design engineers and composite repair mechanics. Metal bonding has been included partly because the defi nition of "composite" can be interpreted to include metal-skinned honeycomb panels, and partly because some composite parts have metal fi ttings or reinforcements that must be treated before bonding. This third edition also covers a number of the problems experienced in service, some of which may be applicable to metallic sandwich panels, offers suggestions for design improvements, including repair design as a particular topic, and regulatory changes. Care and Repair of Advanced Composites, 3rd Edition, provides solid technical information and training for a wide range of airline staff.

This second edition has been extensively updated to keep pace with the growing use of composite materials in commercial aviation. A worldwide reference for repair technicians and design engineers, the book is an outgrowth of the course syllabus that was developed by the Training Task Group of SAE's Commercial Aircraft Composite Repair Committee (CACRC) and published as SAE AIR 4938, Composite and Bonded Structure Technician Specialist Training Document. Topics new to this edition include: Nondestructive Inspection (NDI) Methods Fasteners for Composite Materials A Method for the Surface Preparation of Metals Prior to Adhesive Bonding Repair Design Although this book has been written primarily for use in aircraft repair other applications including marine and automotive are also covered.
