Mechanical Behavior of Fiber-reinforced Polymer Composites: Fundamentals, Advanced Studies, and Current Trends offers a thorough exploration of key advancements in the study of fiber-reinforced polymer composites. The book begins by outlining the basic principles that govern the mechanical properties of both polymers and fibers, delving into how their interaction determines composite performance. It provides an extensive overview of essential materials, manufacturing techniques, and various testing methodologies such as tensile, compression, flexural, impact, and fatigue tests. By examining how fiber orientation and production processes influence mechanical outcomes, this reference helps readers understand the factors affecting composite strength and behavior. The text also dedicates significant attention to failure mechanisms like delamination, matrix cracking, and fiber breakage, offering detailed explanations of each. It explores the effects of environmental aging on outdoor applications and integrates contemporary topics including numerical analysis, modeling, and artificial intelligence methods.
