Purpose:

• To study the basic constituents of composites, and learn the relationship between the physical parameters of each constituent, and their role in forming the strength and stiffness properties of a unidirectional lamina.
• To develop an understanding of the micromechanical and macromechanical analysis of composite materials.
• To understand and be able to predict the behavior of composites.
• To gain hands-on experience in fabrication, machining, and testing of composite materials.
• To learn the different failure criteria for composite materials.
• . . . .

Required Tools:
 

• The use of PC's with appropriate software (MathCAD, Matlab, Excel, etc.) is expected.
• Composite analysis software packages, such as PROMAL.

Prerequisites:

• ME 2733 Engineering Materials, CE 3400 Mechanics of Materials
• Permission of the instructor (if you don't fulfill the above prerequisites)
