Description
Presents a comprehensive focus on sensor systems embedded in composite materials which provide the monitoring feature of this engineering design Summarizes the fundamentals of structural health monitoring systems including the principles, characterization, and challenges presented by fabrication and signal processing methods Includes two expanded case studies with analyses of challenges, testing methods, and solutions Provides a detailed description of the testing methods used in these examples to understand how the novel sensors work in monitoring the condition of composite woven fabrics This book investigates external and self-sensing sensors for the health monitoring of composite materials and technically evaluates sensor advantages and disadvantages in terms of robustness and signaling, as well as their suitability for structural health monitoring (SHM) in different types of composites. The authors explain how piezoelectric, piezo-resistive, and optical fiber sensors are fabricated, embedded, and tested under different loading conditions, with special attention to the design and signaling of piezo-resistive devices. Data and modeling are provided from tests of a piezo-resistive polymeric composite sensor made with chopped carbon fibers and embedded in woven composites.
