Transforming Composite Materials Education for STEM College Students




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- 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 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- Micromechanical Analysis 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- 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 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
