Classifications of Composite Materials — Lesson 2

This lesson covers the fundamentals of the mechanics of fiber reinforced polymer composites. It delves into the classification of composite materials based on the geometry of the reinforcement and the type of matrix. The lesson also explains the different types of composites such as particulate, flake, and fiber composites, and their respective properties. It further discusses the different types of matrices used in composites, including polymer, metal, ceramic, and carbon-carbon composites. The lesson also introduces the concept of micro and macro mechanics of lamina and laminates, and the factors that influence their properties and strength.
