Dr. Jack C. Roberts, Paul J. Biermann, Instructor

Summary

This three-day course is designed for mechanical or materials engineers and managers that are going to use composite materials, i.e., graphite/epoxy, etc., in aerospace and military applications. This will allow mechanical and materials engineers to use simplified "design" equations needed to estimate the type of laminate for their design. The course also offers engineering managers the opportunity to see the complexity involved in composite design. Each topic will include worked numerical examples. Specific applications from SPFIE, MSX, NEAR, and other programs will be presented.

What You Will Learn

• What are the constituents of a composite, the analysis, tooling and fabrication processes used to consolidate a composite component?
• Understand the effects of fabrication variables on the properties of the composite material.
• What are generic mechanical and physical properties of composites versus traditional engineering materials?
• What are the limits of composites?
• What is a lamina, a laminate and how does the stiffness of each lamina contribute to the overall stiffness of the composite?
• How are stiffness and rigidity used to form two sets of equations that link the in-plane forces and moments?
• How to calculate initial estimates of stresses within a lamina.
• What are various strength criteria, including the Tsai-Wu failure envelope?
