What is a Composite? The History and Technology of Composites. Composites as “The New Age Material”. Advantages of Composites over Homogenous Traditional Materials like Steel. Weight for Weight Ratio. Power over Rust and Degradation. Long-lasting Products. Very Low Cost of Production. One-room Factory Manufacture as Opposed to High Temperature Long Line of Factory Halls Required for Steel. Any shape Obtainable at Room Temperature during Manufacture. Products with High Impact Response. Most Highly Sought for Material Today for Use in Air, Sea, Land and Military Equipment. High Strength to Weight Ratio. The Complexity of Composites as Opposed to the Homogenous Simplicity in Steel. Tailoring to Meet Every Desired Need. The Production/Lamination Methods. Mechanics of Composites: The Constitutive Equations. Classification of Composite Materials: Polymer Matrix Composites; Metal Matrix Composites; Ceramic Matrix Composites; Carbon–Carbon Composites. Recycling Fiber-Reinforced Composites.Mechanics of Composites Terminology: Micromechanical Analysis of a Lamina & Macromechanical Analysis of aLamina: Stress, Strain, Elastic Moduli, Strain Energy. Hooke’s Law for Different Types of Materials: Anisotropic Material,Monoclinic Material, Orthotropic Material (Orthogonally Anisotropic)/Specially Orthotropic, Transversely Isotropic Material, Isotropic Material, Hooke’s Law for a Two-Dimensional Unidirectional Lamina:Plane Stress Assumption. Reduction of Hooke’s Law in Three Dimensions to Two Dimensions. Relationship of Compliance and Stiffness Matrix to Engineering Elastic Constants of a Lamina. Hooke’s Law for a Two-Dimensional Angle Lamina. Engineering Constants of an Angle Lamina. Invariant Form of Stiffness and Compliance Matrices for an Angle Lamina.
