This learning track covers a comprehensive study of Fiber Reinforced Polymer Composites, their structure, applications, and mechanics. It begins with an introduction to the fundamental concepts of these composites, their classification, advantages, and limitations. The track then delves into the intricate mechanics of fiber-reinforced composite structures, exploring concepts like anisotropic elasticity, macromechanics, and micromechanics. It further explores the strength failure criteria in these composites, the impact of environmental changes on their mechanical behavior, and the micromechanics of lamina. The track also covers the hygrothermal properties and elasticity in materials, the macromechanical analysis of laminates, and the classical lamination theory. It concludes with a comprehensive understanding of laminates, their stiffness, hygrothermal behavior, failure, and analysis. The track also provides practical applications of these theories in designing components using Fiber Reinforced Polymer Composites.
