Chapter 1: Introduction to Composite Materials
Define a composite, enumerate advantages and drawbacks of composites over monolithic materials, and discuss factors which influence mechanical properties of a composite. Classify composites, introduce common types of fibers and matrices, and manufacturing, mechanical properties and applications of composites. Recycling of composites. Introduce terminology used for studying mechanics of composites.
Chapter 2: Macromechanics of a Lamina
Review definitions of stress, strain, elastic moduli and strain energy. Develop stress-strain relationships for different types of materials. Develop stress-strain relationships for a unidirectional/bidirectional lamina. Find the engineering constants of a unidirectional/bidirectional lamina in terms of the stiffness and compliance parameters of the lamina. Develop stress-strain relationships, elastic moduli, strengths, thermal and moisture expansion coefficients of an angle ply based on those of a unidirectional/bidirectional lamina and the angle of the ply.
Chapter 3: Micromechanics of a Lamina
Develop concepts of volume and weight fraction of fiber and matrix, density and void fraction in composites. Find the nine mechanical and four hygrothermal constants: four elastic moduli, five strength parameters, two coefficients of thermal expansion and two coefficients of moisture expansion of a unidirectional lamina from the individual properties of the fiber and the matrix, fiber volume fraction, and fiber packing. Discuss the experimental characterization of the above nine mechanical and four hygrothermal constants.
Chapter 4: Macromechanics of a Laminate
Understand the code for laminate stacking sequence. Develop relationships of mechanical and hygrothermal loads applied to a laminate to strains and stresses in each lamina. Find the elastic stiffnesses of laminate based on the elastic moduli of individual laminas and the stacking sequence. Find the coefficients of thermal and moisture expansion of a laminate based on elastic moduli, coefficients of thermal and moisture expansion of individual laminas, and stacking sequence.
Chapter 5: Failure, Analysis and Design of Laminates
Understand the significance of stiffness, and hygrothermal and mechanical response of special cases of laminates. Establish the failure criteria for laminates based on failure of individual lamina in a laminate. Design laminated structures such as plates and thin pressure vessels subjected to in-plane and hygrothermal loads. Introduce other mechanical design issues in laminated composites.
