Description

An introduction to high-performance composite materials, covering both engineering and manufacturing of composite parts and assemblies; basic material properties of the constituents (fiber and matrix); how they combine to form plies, or lamina; how to obtain lamina properties; how laminae are combined to form laminates and how to obtain the laminate properties. Other engineering topics include stress analysis, failure criteria and testing methods. Case studies and lessons-learned will be discussed. Design using composites will include material selection; lamination rules of thumb; weight analysis; fabrication process description; tool design; and preliminary cost and production rate analysis.


Includes instruction, a course notebook, refreshments and lunches.
The course notes are for participants only and are not for sale.

Who Should Attend?

The course has proven very helpful to those wanting a broad overview and/or a crash course in composites; experienced engineers looking for a refresher course; stress engineers wanting to understand how composites really work or fail and what to look out for when analyzing parts, data and margins; practicing engineers and managers with metal experience wishing to expand their skill set; anyone wanting to jump into the field but does not know how to go about it; and engineering teams embarking on new projects involving composites.
