CHAPTER OBJECTIVES
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 compositesRecycling of compositesIntroduce terminology used for studying mechanics of composites
Chapter 2- Overview of Composites
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 laminaFind 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- Micromechanical Analysis of a Lamina
Develop concepts of volume and weight fraction of fiber and matrix, density and void fraction in compositesFind 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- Macromechanical Analysis 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 laminaFind the elastic stiffnesses of laminate based on the elastic moduli of individual laminas and the stacking sequenceFind 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
