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

Durability and Life Prediction in Biocomposites, Fibre-Reinforced Composites and Hybrid Composites focuses on the advanced characterization techniques used for the analysis of composite materials developed from natural fiber/biomass, synthetic fibers and a combination of these materials used as fillers and reinforcements to enhance materials performance and utilization in automotive, aerospace, construction and building components. The book presents key aspects of fracture and failure in natural/synthetic, fiber reinforced, polymer based composite materials, ranging from crack propagation, to crack growth, and from notch-size effect, to damage-tolerant design. Written by leading experts in the field, and covering composite materials developed from different natural fibers and their hybridization with synthetic fibers, the book's chapters provide cutting-edge, up-to-date research on the characterization, analysis and modelling of composite materials. - Contains contributions from leading experts in the field - Discusses recent progress on failure analysis, SHM, durability, life prediction and the modelling of damage in natural fiber-based composite materials - Covers experimental, analytical and numerical analysis - Provides detailed and comprehensive information on mechanical properties, testing methods and modelling techniques
